Hi all, I'm looking for some recommendations as to a cheap, loud, and portable combo amp I can lug around for rehearsals. Ive already got good gear for shows, but now I'm looking for something I can leave in practice spaces, etc. Quality of sound can be sacrificed for sheer volume and ease of transportation. I'd like it to be between 250 and 300 watts if possible. Money isn't that much of an issue, but I'd obviously like it to be relatively cost effective. Any suggestions?
