Hello! I was making some recordings with a friend the other day, and since we were making demos for our troubadour duo I decided to use my acoustic bass, a Fender T-bucket. It had quite old and boring strings, so I decided to put on some flats, TI jazz, to give it a more upright sound. Being unplugged it sounds truly awesome, but when I plug it in I get about 9db difference from E to G. It has always been unbalanced, but perhaps by 3db. The ABG has an under saddle piezo strip, and I made sure to seat it properly after changing strings (wide side of saddle below E and strip centered in the trench). The EQ is flat on the preamp. I have these issues no matter if I go direct into my card, or if I go with a preamp and line input, or if I use my digital preamp with SPDIF. There is a very notable volume difference between strings when plugged into an amp. Any ideas what I could do to solve this?
