Use old FBV express controller as GM controller for software amp sims through USBC adapter.

Mon, 09 Mar 2026 14:15:39 +0000

Greetings all.
I have an old FBV express with RJ45 interface and was wondering if it would be possible to use it as a GM controller through an Ethernet RJ45 port on the mac mini or through a USB to RJ45 adapter to control software (i.e. software ampsims or daw's)?
I can imagine the protocol itself should be different from a standard ethernet but, is there a way to translate it or map it with some form of patch ou code?

Floorboard Wah / Volume Pedal Broken

Tue, 17 Sep 2013 00:32:34 +0000

Hi,

there was a thread about this topic here: http://line6.com/supportarchivenew/thread/13813

but it is read only now, so I start this new thread to tell you about what I just found out in case anybody has a similar problem.

In my case the Volume pedal did not work. It was simply the connector at the amp-side, one of the spring contacts was a bit twisted an did not make contact.

I fixed it and now it works again :-)

If you open the pedal you can check the two outer pins (left and right) of the connector of the wah/volume-board. At these two pins you should measure about 5 Volts if connected to the Amp.

FB4 tap tempo not working

Wed, 12 Mar 2025 16:50:33 +0000

Hi - I just acquired a FB4 to go with my Pod 1.0. Tap tempo works fine on the Pod but not when I tap on the relevant button on the FB4. Am I doing something wrong? Could it be a cabling issue? or is the FB4 just faulty? thanks in advance....

Floor Board Volume goes off after some seconds

Mon, 25 Sep 2023 23:56:46 +0000

Hi,

I have a problem in the floor board that I have temporarily resolved.

The volume of the amp goes down a few seconds after turning on the equipment.

Disconnecting the cable from RJ45 the volume appears again at maximum level.

As I work in electronics, I drew a diagram of the wha/volume board and took some measurements that led me to the conclusion that the photo diode M3 (volume control) was faulty.

I removed the photo diode M2 (wha control) and put it on M3, so now I have the volume but I don't have the wha which I use very little.

My problem now is that I don't know the reference of the photo diode to buy and put it on the M2 to have wha again.

Can anyone help me and provide a part list or schematic of the wha/volume board where I can see the photo diode reference, please?

Floorboard Compatibility with newer Amps

Sat, 22 Jul 2023 18:11:02 +0000

I have an old Floorboard from my POD that I bought decades ago. I now have a new Spider V60 MkII. Is the old controller compatible with the new amps??

Floorboard plus Pod 2.0

Fri, 07 Dec 2018 00:15:16 +0000

Just a straightforward question - does the Floorboard work with the early 'kidney bean' Pod 2.0 (pedal socket labeled just 'pedal') or the later version 'kidney bean' Pod 2.0 (pedal socket labeled 'FBV pedal)? Or both? I understand about the use of the FB4 and FBV foot switches and which Pod 2.0 those work with, but I'm interested in what the Floorboard works with.

FBV Longboard - No Manual

Thu, 25 May 2023 13:52:01 +0000

Recently acquired an FBV Longboard, and it works well with my Spider IV. However I just don't know what to "do" with it. How to configure the stompbox switches, expression pedals, etc. The manuals section on the main website just lists "no manual" for this model.

Nobody uses the FBV2 anymore right?

Sun, 30 Apr 2023 01:44:33 +0000

I was digging through some boxes in storage and found an FBV2 pedal that I haven't used in years. I'm assuming nobody uses this model anymore right? Only asking because I'm trying to figure out if it's worth trying to sell it (I'm assuming the answer is a hard no, of course) or if I should just get rid of it.

Floorboard Controller

Fri, 14 Jan 2022 18:48:28 +0000

I have an older POD2 unit that I control with a Floorboard, which includes the volume and wah pedals. This is actually one of the BEST wahs I have heard. Does anyone know an independent wahwah pedal that sound this good ? Or one that emulates this wah ?

L6 Floor Pod Plus Power Supply

Mon, 10 Jan 2022 17:59:42 +0000

I received a Floor Pod Plus foot pedal and it did not come with a power supply. I have read that it's best to use a OEM power supply as the aftermarket versions aren't reliable or could cause damage. Does anyone know where to source the 9VAC 2000mah OEM power supply? I don't see any other specs on the back of this machine indicating polarity or plug size.

I have opened up a ticket with L6 and reached out to the local USA distributor as well so if I received any updates I'll post them here for others to see.

Older Floorboard Schematics Wanted

Tue, 26 Oct 2021 23:44:00 +0000

Hello,

I'm looking for the schematics for on older floorboard WITHOUT the wah switch under the pedal. This floorboard has SELECT SOUND for the upper left switch, not CHANNEL SELECT. The serial number is F1-005432. I have an AXSys212 with this floorboard. The AXSys rom version is 1.04 if that has any bearing. The floorboard display and LEDs track all settings on the AXSys front pannel. The wah and volume work fine. But pressing the SELECT SOUND is the same as pressing the TAP Tempo Tuner and pressing any Bank switch gives random results. I replaced all switches in the floorboard and checked for any bridges or opens. Two of the old switches certainly were intermittent. They are now all good. The AXSys interprets a Channel Select as a Tuner press among other things. I need to look at the switch voltage ladder and see where it's giving the wrong voltage to the ADC converter in the amp.

I have the schematics for the later floorboard with the wah switch but there are a couple of wiring differences in the connects (or the schematics are wrong.) One problem is that the voltage divider on mine is markes as the wah switch which I don't have. I makes checking the switch ladder difficult.

I am hoping someone has the schematics for this older floorboard. And Patchwizard is you just happen to have it. Or maybe the AX2 prom binary. :)

Thanks for any help!

floorboard, wah pedal does not go to zero

Thu, 05 May 2016 21:26:56 +0000

I am having an issue with my wah pedal on the floorboard. It does not reach the zero position, as in when I have the pedal at the bottom, its still open a bit. The volume works fine, goes to total zero.

I am using this as a midi controller and found this out, as the minimum position is about 22. Has anyone ever dealt with this before? Can the strip be re positioned or anything to make it go down to zero?

Floorboard - which one to use after EPROM upgrade

Sun, 03 Mar 2019 17:31:31 +0000

My original POD has been in store for years due to my travelling

Above the socket for the floorboard there is no writing.

If I press MANUAL when turning on the POD is says POD 2.0

so I must have put in a new EPROM - inside it has a label "2.3"

But I now realise I have made it not compatible with my floorboard :(

1) What pedal board will work with this original POD that has 2.3 EPROM upgrade?

2) Are there any original EPROMs anywhere?

Thanks

Floor Board with Spider Red Face Setup

Fri, 25 Jan 2019 17:51:51 +0000

I have recently purchased a Floor Board for my son's Spider I Red Face amp and I have yet to be able to get it to save settings. I have scoured the manuals and the internet and information I have seen is lacking in detail. I was wondering if anyone out there could help me out on setting my Floor Board up. Any information would be appreciated. I am assuming that you get your sound set up on the Spider and then save it on the Floor Board but I have not found the right combination.

Thanks,

Mark

Line 6 Flextone Duo 2x50 watts Stereo with Line 6 Floor Board

Mon, 21 Jan 2019 21:34:10 +0000

I have a Line 6 Flextone Duo 2x50 watts Stereo amp and just picked up a Line 6 Floor Board. I am confused with how the different channels are recalled and how they are created and saved. I have attached the floor board manual to this post, but I am still not able to operate all the different functions. It would be great if there was someone who owns and uses the same components that I have and could ask questions. I am not great at creating tones as there are several modelled amps and effects to choose from and so many adjustments with reverb, channel volume ect. I have only played with the floor board a bit, but I am sure the more i try it the more questions will come up. Let me know if there is anyone out there that can help. It would be greatly appreciated.

Thanks

Cord for an FVB2

Wed, 09 Jan 2019 14:39:37 +0000

I picked up an FVB2 controller to use on my Line 6 Spider IV ; however, it did not come with a cord. It looks like it could take a standard ethernet cable? Is that correct. If not where can I find a cord for this? Thanks in advance.

Floorboard Making Pod 2.0 Go Silent

Mon, 05 Nov 2018 04:52:06 +0000

I recently purchased a floorboard to go with my pre-FBV Pod 2.0. After I play on it for a few minutes it effectively mutes the Pod. No sound comes out of it until I select a channel. When this happens the display on the floorboard shows 0, the display on the Pod goes blank, and the Manual button on the Pod lights up. It doesn't do this immediately after I've touched the floorboard so I don't think I'm pressing the wrong button somewhere. It also fixes itself if I disconnect the floorboard. Any ideas of how to fix this?

replacement USB cord for Floorboard

Sun, 23 Sep 2018 21:26:30 +0000

Can anyone tell me what the specific ethernet cord guage is required for the USB connection between POD2 and Floorboard? I can't find the specs for the cord on the Line 6 website.

Floorboard Wah Wah not working

Mon, 06 Mar 2017 14:26:25 +0000

I recently purchased a used Floorboard to use with my POD v2. It's in pretty good condition and all seems well except the Wah-Wah does not do anything. I can turn it on, and the light comes on, and I hera a difference in the tone, but when I rock the pedal, nothing changes. I have found a couple posts indicating a transistor seems to go bad occasionally, a 2N 4401. I also found a post during a search indication there was a way to adjust, and referencing a FAQ I cannot find.

The Wah pedal on the floorboard may need to be adjusted if the light is coming on and you are not hearing the "sweep". See the following link for more information:

Spider Valve MK II + FB Shortboard + FB1(How) Can I control additional parameters with the FB1

Sun, 24 Dec 2017 20:45:41 +0000

I use a Spider Valve MK II 112 with an FBV Shortboard. I would like to add an FB1 expression pedal to control parameters other than volume/wah, such as delay mix, reverb volume, gain knob on overdrive, etc.

I have the software for the Line 6 FBV Control.

Is it possible to control parameters such as those I have listed?

If so, is there a brief tutorial to get started available, or could someone post several steps to get started? I have searched, but am unsure whether this is even possible with the equipment I am using.

Thanks!

Shortboard problem-says Line6 nothing works

Fri, 03 Nov 2017 13:59:26 +0000

Hi, My shortboard has developed a fault. It powers up, the volume and wah lights flash once and the display says LINE 6 - then nothing happens. None of the buttons work. I've tried different cat5 cables.

Any ideas? Is there a way to reset it?

I'm using it with a Pod X3 Pro.

Thank you.

Floorboard may be bootleg

Sat, 06 May 2017 11:21:44 +0000

My floorboard has a serial number that apparently isn't acceptable in the product registration format. Should be seventeen digits long and instead is more like nine. Anybody else having issue with this? I bought mine from a resale place in Houston. Line 6 support have been feeding me erroneous information and I need real help with this question.

I can't register my FB4

Thu, 18 May 2017 18:02:04 +0000

In my account, I try to register my FB4, but there is a message that says that the serial number is not good for this product.

The serial number that I read on the FB4 is :

FB4 030871

4932 00

I tried "030871 4932 00", "FB4 030871 4932 00", "FB4 0308714932 00"

What am I doing wrong?

Issues with Bank up/Bank down switches

Wed, 12 Apr 2017 12:25:10 +0000

Hello all. Well, I got the issue resolved with the Wah and now have another problem. When I power up the POD everything comes up and works normally. I'll see the Channel and bank in the POD readout, and the floorboard's corresponding Channel LED is lit, and the LED readout shows the correct bank. If I then try to Bank up or Bank down, the channel LED goes out on the floor board, the Channed disappears from the POD readout, the floorboard shows the new bank number, but the pod remains on whatever bank it was on, and nothing really changed. If I change channels from the floor board, everything goes back to normal, but chokes again if I try to Bank up or down. Everything else seems to working fine. This all worked prior to the Wah repair. Any ideas what might be going on???

Floorboard as midi controller

Wed, 23 Nov 2016 22:46:21 +0000

So I'm trying to find out if there's a way of using my old floorboard as a midi controller for my MAC (logic/mainstage). Obviously it sends some sort of signal over CAT5 which I could hook up to my MAC but is there any way to get the 2 talking? Anyone??

Floorboard switch fault

Mon, 18 May 2015 13:14:25 +0000

I have been having a little trouble with my floorboard lately- having opened up the unit and cleaned the micro switches with switch cleaner, tightened the PCB screws, checked the seating of the PCB interconnects, cleaned the RJ45 socket, tried a new cable, and reset the POD 2.0, I am left with one consistent issue.

The 'Channel Select'/'Effect on/off' mode lights do not light after startup (although they do light with all the others when turning on the POD with the board connected). The board will be in 'Channel Select' mode, so I can cycle through the banks and select a channel. However, if I want to enter a patch to alter the effects, drive, or boost functions, the 'Channel Select'/'Effects on/off' switch will not take me into the other mode, but simply show that the patch has been edited, showing an 'E' next to the Bank number on the board and 'edited' on the POD itself. Selecting a patch will return things to normal, but I am left without the ability to alter any of the effects in my patches. Particularly troublesome as I would usually use the 'boost' within a patch for solos.

Is there a simple explanation or easy fix for this behaviour?

Many Thanks, Andy

FBV Shortboard survives spills

Mon, 08 Jun 2015 03:26:41 +0000

A strong reason to separate sophisticated electronics and connections from the foot switches that control them comes from the actions of certain crazed fans (or band mates) at the front of the stage in a small venue or party. I'm glad I had this foresight when I decided my rig would be FBV (placed on the floor) + POD HD (placed in a container). The photo I added here shows what can happen when guests with drinks get invited on stage without prior screening. Thankfully, I just wiped it off before the next set, and it worked great!

FBV longboard pedal LEDs are dead?

Sun, 20 Jul 2014 16:08:33 +0000

I recently discovered a problem with the pedals of my FBV longboard. When I connect it to my PodXTPro, after about 3 to 5 seconds the sound drops dead. When I unplug it again, the sound comes back.

I tried the calibration procedure, but none of the pedal indicators (position and midi) don't change when I move one the pedals. If I unscrew the bottom and connect it then, I see some slight change.

Does this mean the LED of the pedals is dead?

Doesnt Function When Circuit Board For Wah/volume Connected

Tue, 11 Mar 2014 22:34:11 +0000

i picked up a used foorboard to use with my spider 112. when i first plugged it in i got no sound out of the amp, none of the switches worked properly and the on/off function on the wah pedal restarted the amp.

i disconneceted the circuit board for the 2 pedals and everything else functions properly now, but it would be nice to get the pedals working too. the circuit board looks ok to me (but i dont really know what im looking at). does any body have any ideas for a possible fix? or suggestions to further diagnose the problem?

Fbv4 Lights Not Working

Tue, 04 Mar 2014 21:29:22 +0000

Hey guys,

I've had a Spider 112 amp and I recently bought a POD 2.0 to use away from the amp for practice through headphones. THe POD 2.0 came with an FBV4 footswitch. SInce I didn't have one for the Spider line 6 amp I figured I use the footswitch for that as well. Come to find out that the FBV4 isn't compatible with the Spider 112 amp. Now when I plug it in to my POD 2.0 the lights no longer work so I can't visually tell which is active unless I look on the POD 2.0 display. By plugging the FBV4 into the Spider amp, did I just fry out the circuitry for the lights? If so can I fix it? Hope someone is familiar with this.

Thanks!

Pedal Cable For "old" Ver 2 Pod?

Tue, 14 Jan 2014 18:30:44 +0000

I own an old ver 2.0 POD and am looking to buy a used fb4 footboard. There is no cable with it - is this just a standard rj45 cable, or is there a special Line 6 cable?

Intermittent Switching Fb4 With Spider 210

Sat, 23 Nov 2013 06:14:14 +0000

I just picked up an FB4 pedal to go with the Spider 210 I recently bought from an uncle. I plugged it in and it doesn't reliably switch between the different programmed channels on my amp. It goes to one channel pretty reliably (though not perfectly) and the others steadily worse. One channel doesn't work at all. What could this be? I don't mind soldering parts onto the board if that's what it takes...

Thanks.

Display On Fbv Shortboard Mkii While Connected To Usb

Sun, 20 Oct 2013 02:32:00 +0000

Hello,

I am trying to figure out what the display on the floorboard shows when connected via USB to another device. I read in the advanced manual that the midi control information is shown. Does anyone know if (instead) information from the device can be shown (ie patch names, tuner information, etc.)? Is there a setting that would enable this to occur?

My plan was to buy a Kenton or iConnectivity USB to Midi device to hook up the floorboard (usb) to the device (midi).

Thoughts? Thanks in advance for our help!

Fbv Shortboard Led Going Out

Thu, 19 Sep 2013 20:44:43 +0000

I have an FBV Shortboard that I purchased with my Flextone III Plus. It works fine; but as of a week ago, the LED display has been going out randomly. It will come back but I never know when. I'm thinking that I might have a loose connection somewhere. I take it everywhere and all the loading/unloading might have jostled something loose. Anyone experience this before?

Squeeze All From Fbv4

Tue, 30 Apr 2013 03:16:47 +0000

Hello all.

I have a fbv4 and a spider iii... Have some doubts...

The only info I have about the obvious functions of changing channels are tap tempo And hold lit channel for "manual"...

What is manual?

Is there any way to change the bank with it?

Any other feature?
