Matchbox by Runoffgroove

From Runoffgroove.com: 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.

*The wiring diagram for the Tone switch and Cut control in the kit is opposite to be more intuitive. Tone switch is fullest at counter-clockwise position. Cut pot is brightest at clockwise position.
** The OLC version goes further and makes Ge_Whiz's mod (47n and 50k-b pot) standard in the kit.
