Another thread inspired me to start this one: I had never really paid attention before...but I run an Ampeg B2(rack mounted)and a GK 410 cab. Before I even get up to band volume, both the peak (pre) and the limit (power) lights blink on and off as I play. Out of necessity I go ahead and run it higher (where I usually do anyways but never knew enough to be too concerned) and the lights are hitting pretty steady. I get no distortion from my cab, no audible signs of trouble at all...in fact the tone is great and rock steady. Will adding another cab change the point at which the amp clips or no? I like this rig alot and dont want to fry it, maybe I just need more power?
