Hello, I am running a Warwick Thumb 4 through my pedal board and into an Ampeg SVT-4PRO. This then goes via Speakon cables to a PR15H and a PR410H. I am not currently using Biamp mode as it actually seemed to have less punch. We recently added a second guitar to the band and I can no longer keep up. The peak light is almost constantly on as is the limit light. I have tried all varieties of gain/volume combinations. My band (luckily for me) likes a large bass presence. They call it Lead Bass with 2 rythym guitars (even though they both play through Mesa Boogie Triple Rectifiers) I am considering buying another power amp. Does this sound like the right solution? Can my speakers handle it? (I am technically dumb!) I'd appeciate any suggestions!!!!
