Someone told me about a bassist who had that kind of doohickey on his rig... and he had it set up so whenever he went up to the 12th fret and beyond, pipe organ sounds would accompany what he was hitting (jazz walks, mainly).
All this fancy pants microchip computer stuff is beyond me. However, the general idea is an intriguing one.
What is the purpose of such a set-up? They seem to come standard with much of what Brian Moore (the "iGuitar") makes. And what all can you do with it? :confused: Please state it in language at the level of someone who never really graduated beyond old school Nintendo.
