Thinking about getting a cheap bass to experiment on, but my idea is adding a couple of pots onto the bass for quick parameter twiddling (saves bending down) & maybe adding something similar to a whammy bar idea, but connected to another pot (that could be useful for a freqbox or ring mod).
Obviously I wouldn't want another wad of wires coming from the bass, so I'd need to fit another kind of multisocket to it which could then go to a distribution box. Just something simple that the multi lead from the bass goes into & then has jacks for plugging into the MFs. I'd probably need to have a junction box if I plan on controlling something that I want the EP-2 to be in also.
The handy thing is, my dad in law is a joiner to trade & has all the luthier tools I could dream of & he's more than happy to carve up some wood. So if it works, I'll get some Warmoth or similar parts & a body blank for a final creation (my only fear of blanks is getting carried away & make it some stupid shape! ).
