I've heard of it being done (most recently by a local Brisbane band called The Dead), but i've also heard it's a bad idea? I want a new toy, namely a standard (trebble?) guitar, i do preffer bass, but i kind of want a guitar to mess with as well. Would i need a new amp as well? I have a medium sized practice amp, a Peavey 10" 20W "MAX10 bass". I don't want to spend too much. If i can use that amp with a trebble guitar, i could get a nice little Epiphone SG entry-level or somthing else in that price range. If not, i might just get a cheap little no-name starter kit like my kid-brother has. the cable at least works for both, right?
