Spider FX Infusion (1.52) Update FAQs


Q: What is the Spider FX Infusion?

A: Spider FX Infusion is offered as a free firmware (1.52) update for all Spider IV (75, 120, 150, 150HD) amplifiers owners with a Line 6 FBV MkII Shortboard„¢ or Express„¢ Controller device.



Q: Do I need to have the Mk II version of the FBV Express or shortboard to update the firmware on my Spider IV (75, 120, 150, HD150)?

A: Yes, as the previous FBV (Mk I) does not have the USB connection necessary to connect to a computer for the update. You will also need to have the FBV Mk II Express/Shortboard registered to your user account to complete the install.


Q: How do I connect my Spider IV (75, 120, 150, HD150) to my computer to perform the firmware update?

A: See the following link for the Spider IV update information:

Q: What new effect models are included in the Spider FX Infusion firmware update?

A: There are 28 new effects in the update 1.51 (there are no changes in the amp modeling). Here are the locations and descriptions of the new effects:


FX-1 - Gain

Blue Comp: Based on* the Boss® CS-1 Compression

Vetta Juice: A Line 6 original originally created for our flagship Vetta II guitar amplifier.

Boost & EQ: A stompbox compressor that also provides you with some EQ controls so you can further shape the tone.

Screamer: Based on* an Ibanez® Tube Screamer®, the overdrive heard round the world.

Killer Z: Based on* Boss® Metal Zone, the industry standard distortion pedal for metal players since 1989.


Octave Fuzz: Based on the Tycobrahe Octavia, the classic fuzz+octave effect.


Bass Overdrive: Based on* the Tech 21 Bass Sans Amp


Clean Sweep: This is a wide range sweeping filter with a slow decay. It’s similar to Auto Wah, but with a band pass filter shape.


FX-2 - Chorus/Phaser

Analog Chorus: Based on* the Boss® CE-1 Chorus Ensemble.


Square Chorus: Based on* the Boss® CE-1 Chorus Ensemble, but with a square wave acting as the magical modulator.


Random Chorus: This chorus uses three different modulating filters all running randomly.


Jet Flanger: Based on the A/DA Flanger.



Lumpy Phase: Kinda like a Uni-Vibe®, but more radical.


Warble-Matic: It can produce a nice mild phasey sound or with the depth maxed you can simulate the sound of an alien spacecraft .


FX-3 - Delay/ Sweep Echo

Analog Delay: Based on* the Boss® DM2 Analog Delay.


Stereo Delay: Run this effect post in order to hear it in stereo, with one delay on the left, and another on the right. The time parameter sets the left delay’s time, while offset sets the right delay time as a percentage of the left. So, if you set time to 500ms, and offset to 50%, your right delay time will be 50% of 500ms in other words, 250ms. This effect will be summed in mono on a mono amplifier (i.e. Spider IV 75) but will be in stereo when using the stereo line out.


Bubble Echo: Bubble Eko has a Sample and Hold filter on the repeats. A Sample and Hold filter takes a filter sweep (like the one on Sweep Echo), chops it up into little bits and rearranges them semi-randomly.
