greetings! i'm looking for a way to amplify my upright in larger venues, like rock clubs, without losing the integrity of the natural acoustic sound. i need a lot of power and volume to cut through, but i really want to stay true to the sound. does anybody have any suggestions for amplification, speakers, pickups/mics, etc.? for the past few years i've just done smaller jazz gigs with a realist pickup and a gk combo amp...which worked great, but obviously this setup isn't going to cut it in a louder room. any suggestions would be greatly appreciated. thanks!
