I'm pulling this out my bass to put in a 3-band of the same kind. I'm so used to having a 3-band and I don't want to change. I can include the wooden knobs. I will post pictures of the knobs. I can't pull the pre until USPS delivers my new one. These are $185 new at bestbassgear. Controls are vol(pp)-blend-bass-treble. Treble also is a tone knob in passive mode. I will sale this for $100 including shipping to CONUS.
