Just finished my build and thought I'd share my experience. All in all it went together just fine, with a couple little mishaps here and there (Like soldering the volume pot on the other side

) I used the 1590J enclosure and I cut the openings with a drill, a jeweler's coping saw and some flat files. Took a little elbow grease but I thought it went easier than I initially expected. The aluminum of the enclosure while being appropriately thick, it's soft enough to cut and drill quite easily.
For extra input (and extra fun) I added an expression pedal input. I got the Moog EP-3 (

Took a bit of digging to figure out how it's wired, but to save you some time, here's what I needed to know about the jack's wiring: the tip is the fader, the ring is the + voltage and the sleeve is the ground. I measured the voltage and it's not quite like your plain pot, the voltage drops about to half, so you'll need to adjust the MIDI range - but it works just fine and it's mighty fun to have as an added way to modify the effects.
I used some Moog knobs (

Started playing around with the synths by hooking it up to a midi controller keyboard and it's really cool. There's a whole new world of possibilities to explore!
