I've been thinking about purchasing a pickup for my upright to do larger gigs with. I have a very nice amp (cost a pretty penny too), its a Crate BT220 220watts driving a 15" speaker, Crate has proved itself to be better than i suspected. So its a great sounding electric bass amp, but what i'm worried about is the accuracy of the sound of my upright plugged into it. Is it even worth buying the pickup? or will my amp mess around with the sound too much? Anyone who's done this or in a similar situation? Input is much appriciated.
