I finally heard that perfect tone. Arrived at an outdoor carnival to pick up my daughter. A classic rock band was playing some 50 feet away and the bass player had the most perfect tone. Deep, crisp, clear but thumpy. I was off to the side and unable to see his amp. Bass was a black Jazz. My daughter was pulling my arm begging to leave because she was late to a sleep over. Torn between duty to child and discovering that elusive perfect tone, I high tailed it to the car, drove her to the sleep over and jetted back to the carnival to take notes on bass player's rig. Arrive back and the band is gone. As usual, I missed the pot of gold at the end of the rainbow. In the meantime, because I am usually having to quickly plug into rehearsal studio amps rather than my own, I found the best tone setting for my ASAT and leave it. I will adjust the amp to achieve the correct tone. With so many different rigs out there, once I start trying to adjust the bass and rig it seems to turn into a totally mess.
