Adjusting volume control and gain controls provides a wide variety of tones in spite of it's simple construction. The Turbo switch provides an additional boost in volume and less internally generated distortion. The pre-painted black enclosure, red control knobs and red LED indicator give the Thunderdrive Deluxe an understated attractive finish. It is capable of overdriving the preamp section of your guitar amp or adding it's own layer of distortion at lower volume. The current draw of this pedal is very low at 1.3 milliamps, allowing for long battery life.
