I'm thinning the herd. Will post pics later, but, for now, just descriptions: 1. Markbass little mark II, great shape, works perfectly, w/Bag, $340 2. Older GK 400rb, very nice, works perfectly, $210 3. Crate Power Block, technically a guitar amp, but I've used it with great results running a tech21 bass driver through it into a 4x10, $125.
