Got it about a year ago. Killer amp. Touch sensitive en very well built. Like a tank so to speak. Play rockabilly using a Gretsch and a slapback echo. Since I`ve got this amp I`m using less and less pedals. The tone is truely in the guitar, cable ( or wireless ) and amp. With this amp realy every guitar sounds better. The best sound besides my Gretsch is a`62 AV vintage telecaster. Never heard that guitar sound so clear and crisp. Amp sounds clean and crisp till about 3-4. Above it`s getting more beautiful. It`s realy an instrument by itself. The weight is another plus. After carrrying a Bassman or a Koch Classictone this realy is a portable amp!

I found the problem, it was the Rectifier tube, replaced it, no more problems.

New Bandmaster making wind like noise when volume is turned up past 3 on the instrument channel or anytime the mic channel is turned up. I have not changed tube as of yet, but I have removed all of the tube and cleaned the tube sockets, no resolve. Next I guess I will start be replacing the Preamp tube one at a time, any other suggestions?
