I know that this has been discussed here before but I would appreciate some advice specific to my circumstances. I have recently acquired a GB STM 600 and purchased a few weeks ago 2 of the Focus 112 cabinets as a good quality portable rig for band rehearsals and gigs. After playing in practice sessions with the band (3 piece blues) I have some concerns over volume when playing with the amp without having the peak LED on all the time. The peak LED was starting to get very active with the gain boost OFF, the pre-amp gain at 1 oclock, pre-amp volume at 2 oclock and master volume at 3 oclock. Last night I was only just about loud enough with an un-micd drum kit. Your view on the following would be much appreciated: 1) I use a Musicman Stingray 4. Is there any chance the signal from the Bass is too hot for the pre-amp to handle comfortably without the peak light coming on. Should I look at a set up on the bass with a view to lowering the pickups? (never had an issue with the bass with my old solid state set up) 2) The Cabs are rated at 200W a piece but I would have thought they were very capable of taking the STM600 output and i prsume that cab choice wouldnt effect the peak light anyway would it? 3) Would matching 2 x Focus 210 cabs (or a 4 x10) result in noticably more volume at the same amp settings? 4) Is there anything you could recommend (pedal or other separate pre-amp) that I could use to moderate any peak frequecy's from the bass which could allow me to get more volume out of the amp without the peak LED coming into play. I love the GBSTM tone but having invested a sizable bag of loot on this setup I was not expecting to struggle for volume!
