The Midnight Drive is a transparent overdrive. It is not going to change your tone (unless you want to), it is just going to make it dirtier. Also, is a dual pedal for harp. It has an Overdrive and a Booster. The goal of the Midnight Drive is to give you the break-up of a small tube amp out of a clean amp, at any volume. The sound of the Midnight Drive is based on a special type of transistors called FET. I selected those because they sound and react a lot like tubes! The pedals work on a regular 9v power supply, but internally the voltage is raised up to 18v to give you the maximum headroom and dynamic range.
9v dc center negative.
