hey guys i have an ampeg svtcl and an ampeg svt810 and lately ive been going for more of a tube driven sound. kinda p bass with a pick tone but really pushing the power section to get the grit i want. the bass i use is a mia p with quarter pounders and no matter what i set the bass on the amp at it farts. the settings on my amp are flat except a little added treble. the gain is on 3 and the master is on 7. is it my cab thats clipping or is it the head? any help is greatly appreciated.
