Excellent condition MXR x Third Man Hardware Double-Down in limited edition yellow. Comes with original box, paperwork, and sealed pick tin. Great pedal; I'm just thinning the herd and selling my limited-edition yellow pedals. Check my shop for the others listed. Sold as is, no returns.

MXR and Third Man Hardware have teamed up to create the perfect booster for gigging guitar players. The Double Down pedal combines two separate MXR Micro Amp circuits into a single box so that you can heat up two separate signal chains with just the right amount of classic Micro Amp bump.
 
The Double Down pedal’s single input jack splits your signal to two separate outputs, each with its own Gain control for up to +26dB of signal-boosting power. On the left side of the housing is a Phase switch that adds a pronounced stereophonic effect by inverting the phase of the second output signal. On the right side of the pedal is a Buffer switch so that you can choose between true bypass—for the purists—and buffered bypass switching to keep your sound intact when driving two signal chains. 
 
Plug into the Double Down pedal from MXR and Third Man Hardware, and double boost your double stack.
