The Tachyon Amp Overdrive aims to recreate the highly regarded “Lead” mode of the BOSS SD-2 Dual Overdrive pedal. The SD-2 was unique in that it housed two separate pedals in one enclosure, with the “Crunch” and “Lead” modes having their own individual controls for Gain, Tone, and Volume.

While the Crunch mode of the SD-2 was not well-received due to its weak and brittle sound, the Lead mode stood out as one of BOSS’s best drive effects. However, it remained relatively unknown as it was hidden within a pedal that was largely overlooked.

Despite its simple three-knob control layout, the SD-2 had a complex internal circuitry. It utilized five op-amp stages to control gain, clip the signal, and shape the EQ. This approach is similar to that of other renowned drive pedals like the Friedman BE-OD and Dirty Shirley, as well as the Amptweaker Tight Metal.

Overall, the Tachyon Amp Overdrive seeks to capture the unique and highly regarded sound of the Lead mode from the BOSS SD-2 Dual Overdrive, offering guitarists a chance to experience this hidden gem of a drive pedal.
