Hi, guys. Need to ask you something, becasue the combo at my church has started to drift. That is, if you change the settings, there is no way to find your way back! Seems the pots have a stocastic resistance... No, they do not rotate with the knobs. Anyway, I found a few not too expensive alternatives, most of which I never heard before. Anyone have experience of those: Carvin PB100-15 Laney RBW 200 and 300 TraceElliot Commando 15 Torque 1001EB and 2001EB Ashdown Electric Blue The old 150W Carlsbro is powerful enough, but doesn't really cover the frequences I play - I often use the C of the B string, and sometimes even down to F.... Any info welcome!
