I recently received my first electric upright, a BSX T-model four string bass. The thing looks great, feels great, and is a blast a play! That is... until I plug it up to an amp. Don't get me wrong, the tone is groovy, however, the D string is popping and distorting pretty heavily. I know about the trim pots to adjust the levels and even when I turn the D string's volume all the way down it still pops and distorts. I contacted the seller about this and was told that this is "normal" for electric uprights and that I probably have too heavy of a finger. So his suggestion is to adjust my technique. Problem is, is I don't have a severely heavy hand. In addition, I can put three times as much force on any other string and they won't buzz at all... I contacted Dino, the maker of BSX basses, and he is suggesting that I need to send it in to fix the trim pot and/or transducer. However, I want to know have some more opinions before deciding what to do because I don't want to ship the bass in to find out I'm just playing the bass wrong and lose that money and I also don't want to lose my bass for however long it would take to get fixed. I just want to groove but this buzzing is keeping me from it... Note: I plan to record a sample of the bass to let you guys hear it when I get home and have time after classes.
