I found the Schraëg filter while surfing the Modwiggler and lines forums. Described as “Schräg is an expanded repackage of the Bastl Cinnamon multimode filter”. It sounded interesting and I have wanted to try having a project manufactured by a service with SMD components. In the discussion on lines, here, there was some discussion of…
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 circuits are all about controlling the flow of electrons in creative ways. A common analogy…
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 a foot treadle. It can be for a “cocked wah” and boost. It’s also good…
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. I got it out again and set at debugging. After a few minutes with the…
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 doing it. Here is a schematic I found over at https://www.freestompboxes.org/viewtopic.php?t=13062 Q3 and 4 are…
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 into two types sustainer effects and what I’ll call string drivers. Sustainer effects are effects…
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 Face as an amplifier with a gain of 200, a single op-amp can easily replace…
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 they sound good to me. They also offer a feature called Kwikplug. Kwikplug is a…
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 their entry in the FX-X contest of August 2006 over at DIYStomboxes.com. Check out that…
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 to the band! So today is a great day to buy some music! Here are…
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 delay. I decided this might be a good place to start. I tried a few…
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. He designed a few very original effects that still exist on his site. Frobinactor is…
