Hello everyone! I am having some trouble with my brand new preamp, the BBE Bmax, the ss version. I think it may be defective. I get a nasty distortion sound from any of my 3 basses, including one with passive pups. All of my cords are fine, batteries are good. I tried a different preamp and all is good so its not my power amp or speakers. It seems to not be able to handle a hot signal, even if I keep the gain low. I think I tried everything. Has anyone else had this problem?
