Overdrive effect pedal that is specifically modified for electric bass guitar, providing a wide gain adjustment range. It has a Level control and wide Tone control from the lowest bass to screaming trebles so it is very versatile. The Gain on this pedal is very dynamic due to a special design – Gain control offers everything from a very low gain to high gain overdrive crunch with more mid scooped tones. The pedal operates on a standard 9V (negative tip) BOSS style adapter only and is a true bypass for noise free operation. It is also handmade and equipped with high grade components and Neutrik jacks.
