Tremshifter v2
This is an updated PCB for Tremshifter. The original idea is Dead Astronaut effects. I built a few his PCBs, but didn’t like the layout and construction, so I designed my own PCB. My first version had some issues, this…
Tag tremolo
Frobnicator
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.…
Tremshifter Build
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…
Tremolo Matic XXII Build
The Tremolo Matic XXII (Tremolo 22) is a great sounding tremolo. This is origianlly from Stompboxology. I’ve written more about it here. I made a few changes to the original design. This latest version adds a few improvements to the…
Trem XVIII #2
A tremolo from the Stompboxoloy Newsletter. For more information and a schematic check out my previous post about the first build. I had some boards made at PCBWay.com. They prices are very reasonable. You get 10 boards for $5. That…
Tremolo-Matic X build 3
This is a new revision of the Tremolo-Matic X from Stompboxology. You can read more about it here. In a nutshell, this tremolo splits the input signal into high pass and low pass filters and pans between the two. The sound…
Tremolo XXII v2.1
I updated this design again. It’s almost ready for production. In this revision, I improved the PCB layout by moving the components that make up the LFO to the left side of the board and the audio path to the…
New PCB day!
I have a few new PCB projects in the mail today. Flatline Compressor by John Hollis Titan Boost by John Hollis Tremolo-matic XXVIII from Stompboxology Distort-o-matic XI from Stompboxology Bobtavia by Bob Starr John Hollis John Hollis was one of…
Tremolo-matic X by stompboxology
This circuit is based on a type of tremolo that some Fender amp models. Its operation is very interesting. It splits the signal path into a low pass and high pass routes and alternates crossfading between each. It has a…
Tremolo-matic XXII v2
This project was originally from the Stompboxology newsletter. In a discussion about the circuit, the question came up about an extra op-amp used to create a second bias voltage buffer. This appears twice on the schematic as IC1B and IC2. IC2…
Tremolo Matic XXII Stomboxology Update
I updated the Tremolo Matic XXII from the stompboxology newsletter by removing the single op-amp. It looked like this was used as an extra buffer for one of the reference voltages. Everything works without this extra op-amp but there is…
6 new PCBs from PCBWay
I got 6 new boards made at PCBWay.com. The PCBWay.com service is a great deal the biggest cost is shipping. The best deal is to order multiple boards at once since the shipping is combined. This time I waited til…
