I turn the volume on the power amp almost all the way up, probably around 90-95%. The preamp then becomes the "master" volume. I found 9:45 or so to be a good volume for the room I was playing last Saturday. The soundman miked my cabinet and did not take a direct line to the P-A.rockstarbassist said:What about is your volume setting on your amp as opposed to your pre? You said your pre is around 3 1/2 (so I'm guessing about 9:30?), but where is your power amp with that setting? Just didn't know if at the time I was running the amp too low and the pre too high, etc.. Something I might just need to know!!
