I always like some kind of preamp for acoustic instrument pickups. A Boss GEB7 bass eq pedal, Behringer bass amp modeler, Behringer acoustic amp modeler, Behringer Eurorack MX602A mixer, all serve occassional duty in my kit, but a specialized dedicated preamp from Schertler, Fishman, or LRBaggs might be more appropriate. Whatever you decide on, I recommend DI capability, ground lift, and some tone control.

A preamp gives YOU control over your sound and warms up the signal.

Peace, Mooh.
