Are there any other websites that my fellow UGers know about? Musician ads here only finds me more guitarists (which I don't need). I've already joined gazillions of websites but none seem to work. Any suggestions of more ways to find band members?
Put up an ad in a DRUMMER'S magazine.

Looking through personal ads in guitar mags, they always write "guitarist seeking to start a band" or "singer needed", but who is gonna read those? OTHER GUITARISTS. That makes no sense. If you put an ad in a drummer's mag, you'll at least be targetting the right audience.

Or put up a note at your local music store.
