Looking at moving into one of these as my primary amp. I understand they are hybrid with the tubes in the power stage and SS in the preamp which kind of seems backward, hindsight being 20/20. I played a 2x10 one hundred watt version today, but the store didn't have a nice distortion pedal to put in front of it. The cleans were really nice, and I didn't mind the built in distortion for rhythm playing, but I need a real searing lead tone. Also I couldn't get the "chugga-chugga" on the bass strings without it losing low end definition. I don't know if that was a result of the 10" speakers or the built in distortion. Anyone with experience with these that can chime in please? Thanks.
