A collaboration pedal between Third Man Hardware, headed by Jack White, and MXR CUSTOM SHOP! The MXR Double Down is a signal splitter/booster pedal that combines two MXR Micro Amp amplifiers into one pedal. It has a signal splitter function that divides the signal from the guitar into two outputs, and each output has independent gain control that can be boosted by up to +26dB. The heart of this booster uses the same circuitry as the Micro Amp, perfectly inheriting the clean, crisp, traditional MXR sound. This pedal is a must-have for guitarists who actively create their sounds using two amps, like Jack White. The phase switch on the left side of the unit can be used to invert the phase of OUT2, preventing out-of-phase signals when using two amplifiers. The switch on the right side of the unit allows you to switch between buffered bypass and true bypass.
