It belongs to my guitar player who is also a bass player. He just had it re tubed and an adapter made so it will work with a 1/4 inch jack on a speaker cable. I'm interested to hear what it sounds like since alot of players consider this the end all and be all of bass amps. Since I've always played Ampeg SS amps except for my brief encounter with the SVT3pro. It'll be interesting to hear this amp.
