Sadowsky bass preamp and headphone amp RSD-1

This is a rare Sadowsky outboard bass preamp with heaphone amplifier. It is not a pedal, it is the "desktop" version with a number of additional features. I have used it for silent rehearsals at home plugged in, but it works with two 9 volts batteries. It has a headphone out as well as an aux input for an Mp3 player (or your phone). Furthermore, with an extra input and extra headphone out, it can accommodate a fellow guitarist for a silent jam (this is the suggested use in the accompanying manual). Of course, it also has a DI out and the regular output for your amp. You can boost your passive bass with the famous Sadowsky preamp and get the unmistakable Miller sound. I am the original owner and the preamp comes in the original box with the original papers. Never gigged with, used only at home.
