Maybe it's a crazy guitar thing

[lburton2]

An associate of mine at a local music store is trying to accomplish (seemingly) the impossible.. If something like this exists, PLEASE let me know..

Here's the story:
He loves the clean of his Fender Amp.. and loves the distortion of his Marshall... So he wants an ABY to split the signal from his guitar to both amps so he can switch between one to the other during live performance.. This is where is gets weird (dumb?)..

He wants to "blend" between one amp to the other.. In other words.. he wants to be able to use something like a volume/expression pedal from 100/0% clean/Distortion to 50/50 to 0/100% clean/distorted amp..

The only way I can think of accomplishing this is to put a volume pedal after both lines of the A/B.. and change them independently.. which would be practical if you had 3 or 4 legs.. which he doesn't. Any suggestions???

there was an RFX volume pedal that supposedly allowed for a pan function that MIGHT get him what he wants. However, from what it sounds like, he will get drastically different results than what he is looking for. He wants to get a blend between AMP volume, yes? if so, then he doesnt want to do the blending in line with the guitar (if that makes sense).

Google search found this:
Ernie Ball 500K Stereo/Pan Volume and more Guitar Effects at GuitarCenter.com.

Seems to be what you're looking for - from the description it'll fade between A and B.

Neat idea though - never thought of that.

That will probably affect the grit coming from his dirty amp significantly. He may be able to do it if his dirty amp has an effects loop. Even then the quality of results is iffy.

One stereo volume pedal with the wires reversed on one set of lugs ran through the fx loops of both amps should accomplish what your after cleanly.

i feel like they made an expression pedal blend that vai uses. im sure its morley.

and putting less signal into a dirty amp WILL make it cleaner.

second thought, maybe i was thinking of the effects blender.

this fade effect exists in the digitech weapon pedal, but it sucks pretty hard.

You're completely right about the pedal being inline with the amp messing with the signal of the dirty amp.. That kind of slipped my mind..

Southpawpa - your option seems to be the only reasonable way to accomplish this.. But i'm having a hard time visualizing exactly what you're describing..

To accomplish this we'd have to get an A/B box and split the signal to both amps direct. Then take the effects send through the stereo volume pedal.. After that, i'm having a hard time following exactly what you mean by "reversing the lugs".. do you mean plugging one of the amp's send line into the "out" of the stereo pedal?...

Thx for all of the help by the way

actually - upon second look at the Ernie Ball volume/pan.. That seems to be perfect
