This Lab #36 OD-boost is based on the Paul Cochrane Timmy V3.
The Gain and Volume knobs control the overdrive gain and level.
The toggle switch let you choose between two clipping modes (Boost and OD). Internal switch let you selec Regular / Asymetrical clipping.
If you now GUP Tech well, you probably know that we did a small batch of a previous version of the Timmy as the GUP Tech Majestim.
