Here's how I like to build the classic TS overdrive. I've added a three-way switch which toggles between three modes, which helps suit a broader range of pickups and play styles.
SYM - Symmetrical clipping like the classic 808 overdrive. This mode has the most amount of clipping.
ASYM - Asymmetrical clipping begins to ‘look’ more like a valve amplifier clipping. This can better suit input signals which already have a full bottom-end, such as bridge pickups, and allows chords to better shine through.
- FAT - Also asymmetrical clipping, but with a fuller bottom-end output.
The gain knob has twice the gain range than you would expect from a classic TS.
This circuit was made using the following special components:
- Japanese Nichicon film capacitors
- Japanese Panasonic electrolytic capacitors
- Dale Industrial grade precision metal film resistors (1%, 100 PPM / C)
- 600V Teflon wiring
- CIC Footswitch, Switchcraft audio sockets, Hammond enclosure
- Standard sized enclosure
- 9VDC negative tip power
- Battery power option
