Resistors are the most common component you will encounter in electronic circuits. A resistor resists the flow of electrons. To understand this you first need to understand the concepts of voltage and current. Electricity is the flow of electrons. Electronic…
Zap Frequency is a clone of the Systech Harmonic Energizer. This effect is a parametric EQ with variable band width, frequency, and resonance. The effect is very strong! It would make a good wah if you control the frequency with…
Another Super Fuzz build. I used the first PCB I designed from a post over at FreeStompBoxes.org, read about that first build here. This one looked good but it didn’t work! I put it aside because the problem wasn’t obvious.…
The Fuzz by Retro Channel is a Fuzz circuit built around the CA3046 transistor array. It’s a lot like a Fuzz Face and Tone Bender. It makes use of all of the transistors on the CA3046 and sounds pretty good…
We need to talk about sustainers. A sustainer is a device that increases the sustain of your instrument. These come in a few varieties. There are pedal sustainers, handheld sustainers, and in guitar sustainers. All of these can be divided…
Here is an updated post with a schematic and parts for the Deformis. This started as Tim Escobedo’s Ugly Face. I made a few changes. I swapped the LM386 with a dual op-amp. The 386 was used in the Ugly…
If you’re into to cheap guitar parts you have probably heard of GuitarFetish.com. If not you should check it out. They sell an array of pickups that are cheap and get good reviews. I’v tried a couple of these and…
Here is an updated post for the UBE Screamer v2. The UBE Screamer was invented by the smart guys over at RunOffGroove.com, tireless purveyors of all things stomp box from the early days of the hobby. The UBE Screamer was…
I’m a big fan of Bandcamp, it has everything I want in a music service, it supports consuming music by the album, and has great support for music creators. The first Friday of every month they give 100% of proceeds…
I built the PedalPCB terrarium a few months ago. I Finally got around to installing some software and testing it out. I found this post on the PedalPCB forum. Sonic_explorer includes a link to a bin file for a multi-tap…
This is my second try to get this right. I designed a PCB for this earlier but the errors were too great to get around. Quick overview, Frobnicator is a tremolo by John Hollis, one of the original DIY crew.…
This is a board I created for Deadastronaut’s Tremshifter. The Tremshifter is a combination tremolo and filter. It has two LFO’s, one for each the tremolo and filter, with a rate and a depth pot for each. The tremolo section…
