Tools, Tones and Toys for Guitarists
A 3DPT or a 2DPT switch can be used for this. Pete Cornish uses a 3DPT, perhaps because he solders the LED circuit to the switch pins – who knows… I added secondary power filtering on the buffer, which of course, can be easily removed if you already have it on the effect circuit. Stating … Read more
OFF-BOARD SWITCH WIRING FOR GUITAR FX Here’s some common options for stomp switch wiring. If you are new to pedal building, you need to make an effort to understand switching, as it’s one of the fundamentals. 3PDT TRUE BYPASS SWITCHING Make sure you have latching 3PDT switches, or prepare for disappointment. The alternative to latching … Read more
I would recommend breadboarding this prior to committing to solder. The Interfax Harmonic Percolator is very tweakable, and sometimes takes some adjusting to get it right. There’s pages on the Harmonic Percolator on DIY Stompboxes. INTERFAX HARMONIC PERCOLATOR – POINT TO POINT LAYOUT
A bit of a classic – well one of the first guitar effects really, the Dallas Rangemaster. A nice simple one for a quick build using leftover tag board. In theory there is room to fit the output cap on the board too, but I liked the straight lines of the components. DALLAS RANGEMASTER TREBLE … Read more

Looking for some affordable germanium diodes? It’s hard not to go past the price, quality and availability of the old soviet stock. They can behave a little differently than their European and American friends, but otherwise, they are well worth a look as an affordable substitute. BEST 1N341 / 1N34A SUBSTITUTES USING SOVIET-ERA DIODES Д9Б … Read more
A simple mod to provide more flexibility for the timbre range of the Buzzaround. One side of the timbre control is 15khz high-pass filter, which is very high. The useful range of the timbre sweep is rather limited as a result of this, and there’s also a bit of volume loss that comes with this. Some D*A*M … Read more
I just realised I had not uploaded a vero layout for my all-time favourite JFET-based guitar effects. The Barbershop from Fairfield Circuitry. This is a workalike for the Millennium; if you want to make the standard Barbershop, remove the switch and the two capacitors attached. The caps for the tone switch can be anything you prefer. … Read more
While I was thinking of what could be made with tag board off-cuts, this popped into my head. The D*A*M Red Rooster Booster is probably my all-time favourite booster – I’ve only ever made one, and it was so good I stopped there (it was a point-to-point npn version with trimmer). This is a PNP … Read more
