Hey guys, I have a Stingray 4-string and an ampeg 220 combo. I have been very pleased with both, but today I went to guitar center, where I played a comparable bass (cheaper Stingray) on the identical amp. I noticed that it had significantly more punch than my set, which was disappointing considering the amount of money I have put into mine. I tried replicating the sound settings at home, but no doing. I replaced the battery on the active pickup, I changed cords, but nothing seemed to help. Any advice? I was thinking my picjup might be bad?
