This is a used vintage Ampeg V4, These amps have great, clean sound and are very powerful. This amp has been used for many years and has a few items that will need to be repaired. The power button was defective so it was bypassed in order to use. The reverb unit was removed sometime in the 70's (before I bought it in 1983), the Amp face was painted at some point. The volume pots are scratchy. The amp is currently playable but with some minor repairs can be restored to a perfect stage or studio amp.
