Hey, I just recently purchased a Fender Jaco Pastorius Fretless Jazz Bass Guitar for an arm and a leg, but the sound I am getting is worth it compared to my other basses. Now I need to expose its great sound with a better amp. I play funk and jazz music. So what would you recommend as a good amp for my bass under $700? Note: I am willing to spend up to $900 but I only have $700 as yet!
