Handwired Lab Rat

I originally planned to put SMD Lab Rats in these enclosures, but I couldn’t get a version of the SMD layout working the way I wanted it to, so I built some handwired versions into the enclosures instead. This will be the last time I offer the Lab Rat in any form before it’s discontinued, so it’s been discounted above its regular new price.

The Lab Rat is based on the original ProCo Rat, but the original JFET buffer has been replaced by a 12AX7 tube stage. It uses a typical LM308 opamp, and has a three-way clipping diode selection switch, which allows you to go between silicon diodes (standard Rat circuit), LEDs (Turbo Rat circuit), or no clipping diodes for a raw clipped op-amp sound.
