TD-Y

The PastFX TD-Y is a recreation of the discontinued Buffalo FX TDX, itself inspired by the BK Butler Tube Driver—the valve-powered overdrive used extensively by David Gilmour. The current V2 version adds a Mids control and germanium clipping option.

Five controls provide versatile tone sculpting: Gain sets drive amount, Level controls output volume, Bass adjusts low-frequency content, Mids shapes midrange (removable via push button to revert to the original V1 four-knob circuit), and Treble controls high frequencies. A 3-way toggle switch selects between V1 symmetrical clipping, a second clipping option, or no diode clipping mode. A push button removes the Mids control from the circuit when depressed.
