Modified Harmonic Percolator DIY KIT

Modified Harmonic Percolator DIY KIT

Have you ever tried to buy pedal parts online? It’s a mess. Unbelievably, electronic components are used in many other fields aside from guitar pedals, with many more diverse applications. With that said, these other applications need to be operated at extreme temperatures, ultra-high voltages, and many different wattages. If you’ve ever bought resistors from the Internet, and the ones that showed up were giant white bricks of sandstone instead of the little blue striped fellas you’ve seen in your pedals, you’re not alone. There’s a lot to chance.

 

This is why we’ve created DIY kits for you to build ourDistortion Ltd. pedals along with us! Each kit contains all the parts you see in issue one of the Distortion Ltd. articles, and the finished product will exactly resemble the one built in the corresponding issue. If you’ve ever heard the sound clips in our DIY articles and wish you could build one yourself but the part buying is too tedious or confusing, this is the solution you’ve been waiting for.

The parts included are all top-quality, featuring rugged footswitches, Alpha potentiometers, Topmay film capacitors, premium sockets that grip the parts tight, and a powdercoated enclosure. The kit only requires that you have the necessary tools to build the pedal, including a soldering iron and wire cutters/strippers. No returns are accepted on these kits for any reason.

 

This particular kit is for our version of an Interfax Harmonic Percolator, featured in issue #14. The “official” schematic of the Percolator is laden with “some units use [a different] value” footnotes, because of the few originals in the wild being so wildly different. More confusion arose still when chief progenitor fanatic Steve Albini’s unit was borrowed and dissected, revealing a different set of component values not found on even the most annotation-laden schematics. Our version gives you genuine NOS transistors (one germanium, one silicon), NOS diodes (germanium) and a grip of other Percolator mainstays, while offering two extra toggle switches—one that represents the “consensus” schematic and one that represents Steve’s own measured Harmonic Percolator. There’s also a switch to swap out the diodes for silicon or none at all for a wide-open percolation. Get into it.
