to get the most outta the gain structure of the amp, the pad (attenuator) at the front end should be used with active basses and TBirds....the vu meter should dwell around the middle of the dial, the only way to get the most dynamic range out of the pluck imho...I keep the Shape button in the "Out" position at all times, I'm working with my '64 II now because it's going to our next show, the pickup is bassy so I'm tweaking the eq a little....
