COMPRESSION PEDAL Maintains the original sound of the guitar without losing clarity or treble. It has very little noise and a great amplitude that allows you to use it as a Boost along with overdrive pedals. With the Blend control you can add the desired amount of the source signal. With the EQ control you will lighten or darken the timbre. It has a Dirt selector that works in conjunction with another selector located on the side to send the desired amount of overdrive to the source signal. The internal adjustment cannot be touched since it is calibrated with a specific voltage. It works equally well with humbuckers and single coils. It has an XLR output for plugging into a console or studio interface, making it a grounded active injection box. It operates at standard negative 9V and consumes less than 100mA.
