I built this a few years ago. I got it out and played it for a while. sounds pretty good. This is a Big Muffin with a diode lift switch, and a blend control. The PCB is from It…

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…
Mother Fuzz
This is Mic Testers Big Muff Plus. It’s a Big Muff with a JFET input and output stage, and a James control in place of the BMP tone control. The JFET input creates a higher input impedance the on the…
Summon Fuzz a bigger muff
This is Mic Tester’s 21st Century Big Muff. Its the standard big at it’s heart but updated. It uses an op-amp for the input and output stages, a James tone stack, and adds an interesting gain control to the clipping…
Shiva Sonic
I received an email the other day from someone who had bought some pedals from me, it must have been 10 or 15 years ago! I was really happy to hear they were still using and enjoying them! The reason…
22/7 4069
First build of 2022! This is a 4069 version of RunOffGroove’s 22 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…
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…
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…
Wata’s Electro Sound Big Muff
I heard this new song by Boris and it got me interested in the band again. This is apparently an add for a new EarthQuaker Devices pedal. If you haven’t heard Boris you should take a listen. They are on…
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…
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…
New Boards from PCBWay
Just got some new boards from PCBWay.com. These are RunOffGroove’s 22 This is a Big Muff built around MOSFet inverters in place of the Bipolar transistors used in the standard Big Muff. This is a great sounding Big Muff. If…
