Tools, Tones and Toys for Guitarists
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 … Read more
A rare bird in the Colorsound range. Some additional mods can be made. Replace the 3,9k resistor with a 10k pot for a Freq control. And try a PNP Germanium for Q1 which smoothens the feel of the formant filter.. Schematic is avaiable HERE.
Couldn’t resist to draw a schematic and a layout for this interesting mutant of a circuit that just got traced. First two gain stages is almost identical to a Jumbo Tonebender (except for one cap and one resistor value), the third gain stage is almost identical to the saturation stage in a Tonebender Mk. 3. … Read more
Not an auto wah in a normal sense, more like an inductorless wah circuit driven by an LFO. This must be one of the earliest modulation pedals and IMO it is a hidden gem. Lots of murky psychedelic madness can be found in this circuit, especially with a dirt box upfront. Rate and Depth controls … Read more
Here is a rare old and quite unique circuit that hasn’t been traced before. With lots of help from AlexS and cobyjoe we managed to trace it and a have a working clone. So what is it? Not to be confused with the Supa Sustain, this is a quite gnarly and fat fuzz with lots … Read more
An old school, loud, dirty and sometimes noisy compressor that seems to be inspired by Roland Sustainer. The original runs on two 9v batteries for 18v operation so I included an onboard voltage doubler. It might be a good idea to socket both the LED and LDR to fine tune the the compression.
