(Not sure if this was an amp topic or effects topic, so I thought I'd try both.) I'm thinking of making a substitute for a heavy, tube overdriven amp with a good amount of power (about 600W) for live practice and the capability for quiet practice inside my dorm. So far I am looking at the Genz Benz Shuttle 6.0. So I have a few questions: I noticed that many Shuttle owners mostly use the amp in a jazz or blues rock context. I've rarely heard of anyone using the amp in a punk or metal setting. Having tried the Shuttle and feeling unimpressed with the gain, I'm thinking of buying a good tube overdrive pedal for both slight grit and full-on raging overdrive. Has anyone used the Shuttle with a Mesa Boogie Bottle Rocket or a EHX English Muff'n? Back home I played through a friend's Big Block 750 and I was impressed with the tube overdrive section and the cranked tube gain. I've been told that the BB750 and Titan have overdrive sections modeled on the Bottle Rocket. Would the sound of the Bottle Rocket into the Shuttle be close to that of either of the Mesa amps? And a slightly unrelated question: I'm also curious about the blended ss/tube channels and tube gain overdrives of both the Mesa M-2000 and the Genz GBE 750/1200. What would cranking the tube gain and mixing the channels sound like? Would this be similar to an overdriven SVT, or similar to the Bottle Rocket, or something thick and entirely different? Audio samples would be great. Any thoughts?
