I play guitar, although I'm probably a better technician than I am a musician. I like tinkering and I like working with high-performance equipment of all kinds, and electric guitars (and amps) fit into that niche quite nicely.
I recently finished assembling one of those
Saga electric guitar kits (the PRS-style one). It's ended up being a really sweet player, although I wouldn't recommend it for anyone who doesn't have some basic woodworking skills (I had to plug-and-re-drill the factory
misaligned bridge and tailpiece mounting holes). I also upgraded the tuners, pickups, pots and just about everything else too, so ultimately it really wasn't a bargain-basement do-it-yourself project. It has, however, been a great tool for learning about electric guitar wiring and setup though.
