I also use a CMD 121p with Modulus basses. I think it is a great amp but I bought a New York 121 cab to throw under it and that rig can handle ANY small to medium sized room I play. I have also used my GK MB800 with the NY 121 and have been pleased with the tone. Also, the VFE knob at about 9:00 is great at taming the tweeter.
