Brought it home this afternoon. Got it for $550 out the door. It's in better condition than I initially thought. CR serial number with a green jewel light. One Celestion speaker and one WGS G10C. Tilt back legs. It looks like a previous owner had an impedance switch wired in where the extra speaker jack is. Useful for trying out different speakers in the cab (I'm interested to hear how my 12" V30 sounds), but makes it harder to use an extension cab. The Prosonic pop is there when changing channels, but it really isn't that loud. It really won't be noticeable at gig volumes I suspect. This thing sounds fantastic! I see why people can get hung up on how gainy it can get if you really crank the Gain 2 knob, but with it off and Gain 1 on about 2-4 it was just right for me. Cleans are everything I hoped for. I tried a couple other amps in my price range - a Classic 50 in 410 but it wasn't any contest. I hoped to try out a Carvin Belair ($350, so it was appealing), but it didn't work so I never heard it. Also, the first thing my 4-year-old did when I got it home was turn the dials and day, "I'm turning these all to 10!" I win at parenting. 2 questions (for now): 1) Anybody know what model footswitch works with the Prosonic? They didn't have the original. Both a 2-button switch and 1-button switch from their stockpile of extra switches had the problem of rendering the reverb inoperable whenever the switch was plugged in. 2) How can I verify what the actual impedance of the speaker impedance output is? I just want to verify that the 3 positions on the added switch work as they are labelled (see picture). Thanks!
