I am getting confident enough in my upright playing that I want to start using it live. Does any amp manufacturer make an amp that is made just for upright? I could go with an acoustic amp like a Roland or something, but didnt know if it would be voiced right for it. I could use a good tiltback bass amp, but again, didn't know if it would work right. I don't need XLR in's or phantom power, it's an electric upright with a good preamp already. I want to hear options from all price ranges. I am in north america though, so some esoteric brand from Bolivia might not be the best thing to suggest for me.
