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 the first people I ran into posting DIY designs on the internet. All of his…

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 seems redundant. I decided to test this out by making a second version of the…

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 I had 6 boards designed and ready to go before ordering. As long as your…

Vulcan 1.2
I made a couple small updates to the first Vulcan PCB. Got the new boards and did a build to confirm they are working as expected. Everything works as it should! This is a pretty good sounding overdrive distortion. The best part is the ability to clean up the sound by rolling off the volume.…

New PCBs
I had a few new PCB projects manufactured. Here are three projects I had been working on. These were drafted up in Eagle. I had these made at PCBWay.com.the cost was about $45 for 30 boards. I order 10 of each of three designs, they sent me 11 of each, which was a pretty reasonable…

22/7 4069
First build of 2022! This is a 4069 version of RunOffGroove’s 22/7. The original uses the 4049 hex inverter. This the same circuit using the 4069. Both chips contain 6 inverters but the they differ in format and layout. The 4049 is a 16 pin DIP and the 4069 is a 14 pin DIP. One…

UBE Screamer 4069
This is a version of the UBE Screamer using the 4069 in place of the 4049. Essentially these chips are the same. They both contain 6 inverters. The 4049 is a 16 pin DIP while the 4069 is a 14 pin DIP. Electrically the should the same but the pin arrangement is different. The original…

22/7 4069
Here is a version of RunOffGrooves 22/7 using the 4069. The original circuit uses the 4049 Hex inverter. The 4049 is a 16 pin dip with 6 inverters. Here is the 4049UBE data sheet. You can see it has 16 pins with 6 inverters. There is a power Vdd pin 1 and ground Vss pin…

PCBs with pots and LED
I just built a PCB project without the LED taken care of on the board, what a headache! In the old days everything was like that but we have evolved since then! in my most recent projects I have been following the layout used by PedalPCB. I feel like they have hit on an arrangement…

RunOffGroove 22/7
I updated my 22/7 PCB. I had these boards made at PCBWay.com. These boards are great quality. Very cost effective. I’m a fan of OSH Park.com. They are good when you want only three boards, are in the US and need quick shipping. The PCBWay boards are very clean, they offer a range of colors,…

Big Muff
Here is another Big muff. I had these boards manufactured at PCBWay.com. The idea was to make a Big Muff PCB that could be used to easily build any version of the standard Big Muff. The board has an on board LED with all of the off board wiring along the bottom edge. This makes…

Yet another Big muff
Does the world need another? I wanted to do a Big Muff using those 9mm pots. These seem like they might be a good build option. I also wanted to setup this PCB to use the same part numbers that appear on all of the schematics not the Big Muff Page. This way it would…
