I understand that this wouldn't be authorized by line 6 and I've read a few areas where others have gotten this to work, but each that I've read has missing pictures, broken links, or incomplete information. Has anyone been able to make this work? Any help would be greatly appreciated.

Would a rj45 splitter do the trick? I'm guessing it might be more complicated than that lol

Nope. I wish it was that easy to do but the amp powers the pedal and that would send the power twice to it from both amps. I've read in a few places that it's only the green wire (#6) that sends the signal to switch but I've also read some that say it doesn't work and one other that says it does...looking for more clarification

There was a thread and a linked video (or pictures) that someone had done to do this on the old forums here.  A splitter won't work.  Curious on why you want to do this - more volume?

There was a thread with picture (missing), there was also a video where someone modified the direct output line.

I have 2 of the amps and want to run a slightly different effect on each side and be able r

Sorry stupid phone post lol. I want to be able to switch them from the same pedal as well, and no so much for more power but more spread on sound and like I mentioned slightly different effects on each amp. I'm guessing that it's probably not that hard of a mod, but looking for more info so that I don't short something out. I love the sounds in the spider iv, just wanting to link them up.

Ffbrgst, I'm personally curious how you don't immediately see the appeal of controlling two amps at once. Let me break it down..
1. It'd be awesome.
2. It'd be really cool.
3. It would be super awesome.

the jist of the posts describing how to do this, is to get a standard rj45 splitter... one male/two female, and you have to snip some wires in that adapter...

basically the ones that provide power to the pedal...

i've asked the web dev to look into fixing old doc links, not sure if its possible... (things have been moved off the old system)

spaceatl wrote it up: http://line6.com/sup...76460-spaceatl/

you might try sending him a personal message and link him to your forum posts (for the benefit of others)

i'm sure he can fill in the gaps.

I did message him (hope he doesn't mind) but haven't received a reply yet, I messaged just yesterday. From what I've read, its not a standard RJ45 splitter, its some sort of telco splitter with 4 wires? The links that were provided didn't work anymore on where to purchase this splitter. Which makes me curious about splicing in the one needed wire to send the signal to the second amp, if that's possible. I really want to get this to work if its possible to do. I purchased the first Spider IV after jamming on one and love it...I fell into the 2nd one by a friend that was cash strapped, so I got a great deal on it.

 

I want to make sure what wire it is that is need and what wires need to be cut for sure. Ive seen a few posts (here and elsewhere) that are somewhat different, but neither were using the Spider IV amps, not sure if that makes a difference or not. I really appreciate the feedback!

exactly...A RJ45 telco splitter....LAN splitters will not work...that is totally different...This is serial comm(RS232 or midi) over RJ45...Not an IP network.

 

I have only ever used this mod on a SV MK1, Flextone III XL and POD XT...If I am recalling correctly, the Spider IV has midi...have you tried midi out on the FBV amp to midi in on the mon FBV amp...That would be preferred over this mod....The only reason I did it was to use the MK1 with the Flex...I don't need the mod with the MK2 amp since it has midi...

 

What I can say is that you have to follow the instructions exactly...Even then, this mod is a hack... powering up the amps is a little tricky...I have a few notes in the thread about it...IT has been years since I needed it...It was handy at the time...But really more of an academic mod...I just did it to see it would work...It works, but it things can get a little weird sometimes because one amp is only listening and not synchronized...

all the FBV's get powered by the same pair... so i think the pair that needs ommitted would be the same regardless of amp... i think that space originally did this with a spider and a flextone in fact.

The Spider IV only has the RJ45 connector for the FBV MKII Shortboard, it doesnt have a midi in and out. I didnt see a thread that tallked about powering up the amps. It is on this forum? Thanks for the reply!

Here's what Ive tried:

 

1. I cut the end of off one Cat 5e cable (this cable ran the pedal perfectly before cutting the end off)

2. Used 2 RJ45 splitters -C184-03793_chiclet01_ac_mn_294174.jpg

3. Connected all 8 wires to one of them and jumped the green (#6) over to the other splitter.

4. Cable is plugged into the back of the main amp (with the 2 splitters hanging).

5. When plugging into the jack that has all 8 wires, ran to the pedal, the pedal runs the amp perfectly. Plugged another cable into the jack that only has the green wire, ran to the slave amp and it does nothing.

That would be awesome!!

 

The only thing I can think of that might be wrong with my attempt is that the green might not be the right one for the Spider IV or FBV MKII Shortboard.

Does anyone know which wires are power for the pedal? Eliminating those would make testing much simpler ;-)

RJ45 Pin # Wire Color
(T568A) Wire Diagram
(T568A) 10Base-T Signal
100Base-TX Signal 1000Base-T Signal
1 White/Green Transmit+ BI_DA+
2 Green Transmit- BI_DA-
3 White/Orange Receive+ BI_DB+
4 Blue Unused BI_DC+
5 White/Blue Unused BI_DC-
6 Orange Receive- BI_DB-
7 White/Brown Unused BI_DD+
8 Brown Unused BI_DD-

This is what confuses me in deciding which to splice to receive signal to the 2nd (slave) amp. I've read in a few other posts that it's #6 green, but from the looks of this it could be #6 orange. I'm not very knowledgable on rj45

Do you know which pair powers the FBV?
