So I posted a topic a few weeks ago about our band's vacant guitarist and drummer positions and we got one reply but that person hasn't e-mailed us in weeks so does anybody have any good advise on any other places to ask???

local music stores..
Myspace Classifieds is probably your best bet

Newspaper if you want to pay

but try Myspace
Are you close to a university with a music department? I would try there.
Epiphone SG
Crate V-18 212
Xaviere XV-500
Boss PS-5 SUPER Shifter
Digitech Bad Monkey

Bandmix.com has alot of people on in your area and other areas. It costs money to be able to send messages to ppl, not nothing to become a member and post an ad, and make a profile...SOOO if you want response, but don't want to pay the money...post your email adress. Not everyone does this so it sucks having to wait for a response.
