Here is an Audere 4 band classic preamp. It was wired with a preamp on/off switch but the leads kept falling off so I bypassed it. It comes with the 3 way Z switch which is really cool for a quick change of tone on the fly. This is the 4 knob 1 switch setup with 2-9 volt battery clips. Comes with gold knobs. The setup is Vol, Balance, stacked treble/bass and stacked lo mid/hi mid. I will include the bypass switch. Jack is not in the pics but is also included. If you need any help wiring this you can get in touch with me after the fact and I'll help as much as I can. Here are some wiring diagrams and pics. $120 shipped.
