Officially Licensed Circuits Runoffgroove

From Back in the mid-90s, the Matchless DC/30 became one of the first boutique amps to hit the market. It excelled at clean tones, as well as thick Vox-like overdriven lead sounds. An item of interest in this circuit is the odd-looking Tone control. This is in some ways similar to the FAC control on old Orange amplifiers. The sound is "thinnest" on setting *A, and gets thicker as you progress through the settings. The Cut control acts as a simple Low Pass Filter. As you turn it counter clockwise, it will roll off some of the treble frequencies. We departed from the schematic a bit here. We used a 10n cap where the amp used only a 2n2. The reason for our deviation is to achieve a more dramatic effect.

  • True-bypass
  • Four controls: Gain, Tone (rotary switch), Cut, Volume
