Keeley Super AT Mod Overdrive Limited Edition

Keeley · pedal

The Keeley Super AT Mod Overdrive is a limited-edition premium modification of a Tube Screamer-style overdrive circuit by Robert Keeley, incorporating signature AT (Andy Timmons) circuit modifications that extend the tonal range and improve harmonic character beyond the stock circuit. The AT modifications address specific Tube Screamer limitations including bass response and clipping character, producing a more natural, harmonically complex overdrive suited to expressive blues and rock lead playing.

What stands out

  • “Valued as the original Andy Timmons signature overdrive collaboration, offering a distinct asymmetrical-clipping character before Keeley and Timmons expanded the concept into the more feature-rich Muse Driver”

    — from the community notes

  • “Asymmetrical clipping gives a genuinely different compression and harmonic response than the symmetrical-clipping Super Phat Mod, an important distinction for players comparing Keeley's overdrive lineup”

    — from the reviews

  • “Full-range frequency response is a specific design goal,”

    — from the reviews

  • “Primary use case is players wanting full-range, dynamically responsive overdrive true to Timmons' specific tonal preferences”

    — from the community notes

  • “As the predecessor to the 4-in-1 Muse Driver, it offers a simpler, more streamlined control set for players who prefer fewer tonal options to navigate”

    — from the reviews
