A Single Box with Double the Boost

The Double Down boost pedal crams two MXR Micro Amp circuits into one compact box, offering guitarists double the gain in a single stompbox! Fittingly, the creation of this pedal’s dual-boost power required the minds of a dual-company collaboration — it’s the brainchild of longtime pedal masters MXR and the hardware division of Jack White’s Third Man Records. So, what makes it so special? The Double Down’s two Micro Amp circuits are completely independent, allowing guitarists to supply up to +26dB of gain to two different signal chains. What’s more, the Double Down is packed to the brim with utility features, including both a phase switch and a bypass switch to perfectly dial in your rig. If you’re running a dual signal chain setup, then the MXR/Third Man Hardware Double Down is the perfect boost to push your rig to the limit!

Two independent boost circuits

One input, two outputs, and two knobs: the Double Down is a simple yet exceptionally powerful pedal that allows you to drive two separate signal chains simultaneously. While the Double Down provides myriad uses for gigging and recording musicians, Sweetwater guitarists have found that it’s a must-have tool when looking to crank up the heat on a stereo amplifier rig.

Double the switches

In addition to its boost capabilities, the Double Down also comes with two different side switches to tweak your setup: Phase and Buffer. For guitarists who are picky about the purity of their signal chain, the Buffer switch allows you to swap between a buffered bypass and an ultra-clean true bypass. Plus, the Phase switch flips the phase of the second output signal for a distinct stereophonic tone that experimental tone chasers will be sure to love.

MXR Double Down Boost Pedal Features:

  • Designed by MXR in collaboration with Third Man Hardware to create the ideal boost pedal for gigging guitarists
  • 2 independent MXR Micro Amp circuits packed into a single box for double the boosting power
  • Each Micro Amp circuit delivers up to +26dB of gain to push your amp or turn up the volume on low-output pickups
  • Single input with each of the 2 outputs connected to a separate Micro Amp boost circuit — great for driving 2 separate signal chains
  • Phase switch inverts the phase of the 2nd output signal, resulting in a distinct stereophonic effect
  • Buffer switch allows you to swap between true bypass and buffered bypass
