THE CARL MARTIN HEAVY DRIVE IS A PEDAL DESIGNED TO EMULATE THE SOUND OF A HIGH GAIN TUBE AMP USED BY HEAVY ROCK MUSICIANS.

It offers loads of gain, but responds to the guitarist's touch without altering the basic tone of the guitar.

Features

The Attack (mid) and Edge (treble) controls give access to a variety of tones within this type of distortion style, without compromising sonic quality.

The Carl Martin Heavy Drive has enough gain on tap to lead you to Rectifier tone territory without low-string mush or raspy highs.

True bypass

It can be powered with the standard 9 volt center negative adapter or 9 volt battery
