What I did was building myself a sort of 2-floored pedalboard. On the Top shelf is a Roland GR33 synth board which is directly fed via the 13-pin GK cable from a Fender Roland Ready Strat (built-in GK-2a, separate Guitar/Synth volume knobs -single tone pot for the guitar pups- MIDI up/down switches, and 3-way toggle Guitar/Synth/Both switch). From the Guitar out: jack in the GR33 I go into a modified (changed tube and lowered noise floor) Art Tube MP which is set just below the shelf, and from there I go to a Digitech RP2000 pedal, which then handles all my guitar effects for this setup. Then I return -in stereo, speaker simulation activated- to the GR33, and go out in stereo to a double channel DI box also fixed on the lower floor along with a power strip which holds all the P/S. The board has a swivel so I can fold it and get it inside a decent-sized travel suitcase, when I get to the venue I only have to take it out, spread it open, and connect 2 XLR's, the AC cord and the 13-pin cable from the guitar. Since I mix and control the Synth/Guitar mix (as well as adding/substracting sound on the synth patches with the GR33's expression pedal) I mostly have to play sitting down (is quite hard not to fall over while playing and handling all the pedals). I am mostly using this rig in a small group where I have to play bass/guitar/synth lines altogether, therefore I go direct to PA to avoid further hassle. Not the best sound in some cases -specially guitar OR bass- but I have to keep it somewhat portable and versatile. Some weeks ago we had the chance to play with a real keyboard player and I brought a bass instead, it was SUCH a breeze having not to worry on playing several instrument lines at once for a change!
