Got the amp yesterday. She sounds great... I'd love to know what the seemingly very popular "Choke Mod" is and how to do it. I also just checked out the tubes that came with it and am wondering just how good or bad this tube setup is: V1 - Sovtek 12AX7 LPS V2 - Sovtek 12AX7 LPS V3 - Sovtek 12AX7 LPS V4 - Yamaha 12AX7 (original) V5 - Sovtek 12AX7 LPS V6 - Sovtek 12AX7 LPS V7 - Sovtek 12AX7 LPS V8 - Mesa 6L6GC V9 - Mesa 6L6GC V10 - Mesa 6L6GC V11 - Mesa 6L6GC The amp functions fine, but that seems like a lot of LPS's, or is that normal? I just got a Hughes and Kettner Vortex 412 Slant cab to go with it (for the practice space), now I am in search of the best 2x12 cab for my home.
