Hello all. I've been playing a double bass for a while but have never adjusted my sound. I usually play an electric through a Behringer Ultra Bass 4x10 and when I switch to my upright, I just plug it straight in from my Fishman pickup. I know I know...feedback city. I adjust my settings and stand clear from the amp. However I have a Boss ME-120B and was wondering if I could use this as an equalizer/preamp for my upright. Any suggestions?
