Add distortion to your pedal board with this Distortion Mini Pedal from Monoprice! This mini pedal produces a modern classic tone for ROCK solid performance. It features a variable distortion effect, with high level control. A toggle switch lets you switch between normal distortion and Crunch mode for an extra heavy response. The tone knob adjusts the color of the distorted signal, while the distortion knob controls how much distortion is applied. The pedal features true bypass, so it won't alter your tone when not actively in use. The casing is metal for long term durability. It is powered using a 9VDC power adapter with a negative tip/center, such as our 9V Power Supply for Guitar Pedals (PID 611690). Note that the manual erroenously lists the DC connector size as 3.5/1.1mm. The connector is actually 5.5/2.1mm, which is the same as that of the 611690 power supply. The manual will be updated and posted here as soon as possible.
