Hello everybody! I currently play a mix of tunes with my Yamaha electric cello as well as my acoustic. I've found that the Yamaha is good for rock, but when I play jazzy stuff I prefer the sounds of the acoustic. However, I'm not getting a very good sound out of my amplifier. I use a Fishmann pick-up and it causes a lot of feedback and unpleasant squeaky sounds. I've been classically trained and unplugged for most of my life as a cellist, so this electronic business is still sort of new to me. Any suggestions? All feedback is appreciated.
