Super Frequency
This is my spin on Tim Escobedo’s Ugly Face. The original is a great DIY project anyone that hasn’t built it should give it a try. Super fun, unique sound, parts are easy to get, and it’s not a difficult…
Bigger Muff part 2
Looking at the Bigger Muff. Still not happy with this, it doesn’t sound bad it’s just that the range of the controls is unsatisfying. There are plenty of usable sounds some but some of the settings are not useful. Here…
Peach Fuzz Clone
I have wanted to try the Frantone Peach Fuzz for a long time. The circuit uses one of my favorite chips the LM386. Not only does it use the 386 it uses two in series. Frantone is one of the…
Peach Pit
This is my take on the Frantone Peach Fuzz. Peach Fuzz is an op-amp buffer into a pair of LM386 in series, followed by a tone control similar to the Big Muff. It uses a dual op-amp but only one…
Debugging your Circuit
No matter how many pedals I build they don’t always work, at least not on the first try! Anything can go wrong. Debugging is a skill and an art, that is not hard to master. It’s impossible to name all…
New Batch of PCBs
New batch of PCBs. A couple updates and a couple new things. Here’s this list: I designed the boards in Eagle PCB (I swear I will learn KiCad one day!) and had them manufactured at PCBWay.com. I love this service,…
Causality 6 by Frequency Central
This is 4/6 stage OTA based phase shifter by Rick Holt of Frequency Central fame. Here is a link to epic thread about this and a 4 stage design over at DIYStompboxes.com. Here’s my build, which is working but has…
Bandcamp Playlists
Bandcamp added playlists to the app! I love Bandcamp as a service. The one problem is the where and how you can play the music you’ve bought on the service. Playlists expand this in positive ways. Bandcamp has added features…
PedalPCB Terrarium
I put together a Terrarium from PedalPCB. Terrarium is a DSP platform that uses the Daisy Seed by Electrosmith. The Daisy Seed is like an Arduino Nano on steroids with audio super powers. You can read the link above for…
Ugly Face Build
The Ugly Face is a classic DIY Stompbox build. Almost a rite of passage! The circuit, by Time Escobedo, has been around since late 2002! Here is my schematic. Schematic Parts List Part Number Value R1 1M (Tayda, Stompboxparts) R2…
