A friend of mine has an old Bassman 135 that I MIGHT want to buy, but I really don't know that much about. It sounded really good with his bass (Fender J), and I would obviously try mine to make sure. I have a few problems though... 1. The amp head (silverface) is running on 3 of 4 tubes. This thing has seen playing time for 20? years, and probably hasn't had any maintenance in a very long time. 2) The cabinet might have a faulty speaker. The cabinet is huge, and I believe its a 4x12, possibly 4x10. He says the cabinet is in good condition otherwise. 3) From my research, I found that it is only 135 watts. This would probably not be enough for a show, so how hard would it be to mic this amp and make it sound good? 4) I know it weighs alot, but I don't know how much (I haven't picked it up yet). I have a Firebass II and Peavey Cabinet that are 50 lbs and 100 lbs respectively, and anymore than those figures could be trouble. 5) I have absolutely no idea how much I should offer for the two together. I figure I want to replace all 4 tubes together, and get the amp checked otherwise, not to mention the possible maintenence of the one speaker. 6) Does anyone have a general amount for replacing the tubes, and such? I know I'm looking at a bit of maintenance, but I want a tube amp and I think this guy could give it to me for dirt cheap. But, how much is dirt cheap? $100? 300? 500? ^Ed McMahon voice on^ HEYO!! ^Ed McMahon voice off^ Thanks for any input!!
