I'm thinking about making a guitar, as i have an idea in my head, and someone around who can teach me. The only thing is lessons cost money,so i can't waste time deciding what materials/ hardware to use in a lesson.

What i want to make is a semiacoustic strat/ gibson 335 hybrid type thing. I want to use 2 humbuckers as i want a bassier sound, but i'm open to oppinion there. Another thing is, i originally wanted them wired out of phase, but i have been told (i can't remeber exactly how) that there is a way to put a switch in to switch been having the pick ups in and out of phase, is this true? if so how do i go about it? I dont know what sounds better a shorter or longer scale length?

another thing, should i even give a thought to making a frettless acoustic?
