Pocket Rocket bass preamp, 9v headphone amp
Cool rare unit, lets you play bass with a set of headphones and hear yourself anywhere. Runs off 9 volt battery, has normal, bright, and distorted settings, plus tone and volume controls. Also has an aux jack which functions as an aux input and a low level output for recording, etc (or so the manual tells me). so you can use it as a preamp into another amp.

$25 plus shipping
