2 x 104 makes a LOT more sense, especially since it's commonly and CHEAPLY available thanks to Tiptop and their Mantis case. Also, one best-kept secret might be found by checking out Erica's cases; they have a 3 x 126 for about $550-ish with beefy power. It's a little shallow, but as long as you stay under 45mm on depths, you're golden. Plus...the guitar can still go into the modular via the A-119. You lose the stereo return, but the "abuse potential" there is pretty massive with its envelope follower. Run the guitar through something like a Dynacomp to pull the level up on sustain, then just mix it like another "oscillator" while using the envelope follower to control VCF/VCA behavior.
