I bought this amp back in 2005 and have used it on all my gigs. It is the only amp I have. It has a 12" Eminence speaker in it. This is the amp you can lean back. Eminence does not make that speaker any more so if this speaker goes out before the amp does, I don't know what speaker to use that has the same bolt pattern. If you have this amp, do you run an extra cab with it? What are your normal setting.
