Dharma Sound / Colorsound Distorter

Here is a forgotten oldie that has been requested ever since Colorsound released a small run of replicas in the fall of 2023. Dharma Sound was a small operation builder from Kent, OK, active in the 70s. 

The circuit design is pretty interesting; first a BJT input buffer. Then the signal is split into two parallel active fixed filters. The signal is then joined together before it hits the LM741 op amp with stacked clipping diodes to generate distortion. . Sound clips suggest that it sounds like a distortion with a cocked wah tone.

Oh, and this is post #1500!

As with String Slinger, a true bypass mod has been made for this layout.

Modified for true bypass since most people in here seem to prefer it over buffered bypass.

4ms Pedals Tremulus Lune

 There was a request for 4ms Tremulues Lune with two LFO's but couldn't find a schematic for it. So we're stuck with the normal version. But for this layout I've incorporated an input buffer found in their "Luna" project. Schematic is aviable HERE as well different ways to wire up the rate LED and the bypass LED.

 Per request.

This one was a PITA to draw with its four dual op amps and two buffered Vref lines. So it didn't came out 125b friendly and it has more links than I prefer...
