A simple mod for the tubescreamer that adds a led clipping option for more headroom and a different clipping character.
The first step is to find a nice spot for the switch to fit in and drill the hole. Then the toggle connects on the board and the stock diodes and switches between standard and led clipping. Leds will clip less of the signal which results into more headroom and volume and gives the Ts9 a less saturated, cleaner overdrive character.
