EHX Satisfaction Fuzz
March 24, 2014

The Electro-Harmonix Satisfaction Fuzz has been rumored to be a Maestro FZ-1 but after looking at a pcb photo that I saw in one of the guitar forums, it appears to be a Jordan Bosstone. The part numbers are even the same as on the Bosstone schematic I found. You can’t build one for the […]



CLM6000 Replacement

Several of the classic Craig Anderton projects used the CLM6000 optocoupler, which has become difficult to find. The question then is what to use as a replacement for it. I downloaded the CLM6000 datasheet and then checked the Silonex datasheets to find a similar part. It turns out that the NSL-32 opto is almost an […]



Tinaja Quest

While searching for a detail about mosfets today, a search link led me to Don Lancaster’s Hardware Hacker archives. I had not been to his site in a long time, and while much of the computer info is outdated, the basic electronics stuff is still golden. There is a wealth of info there, so check […]



Little Angel Chorus – NYE
March 19, 2014

Over the holidays just a couple of months past, I laid out a pcb for the Little Angel Chorus. After building it, I found that a few changes were needed to get the most out of it with my rig.



Differential Distortion 2
February 4, 2014

Ken Willmott published the Differential Distortion design in Popular Electronics, August 1995. He revised the design in 2014 and it is included on the AMZ schematics page with his kind permission. Thanks Ken!



NPD: EHX Soul Food Overdrive
January 21, 2014

New Pedal Day! The EHX Soul Food Overdrive. I spent about 30 minutes looking at the pcb, and as far as I can determine, this pedal does seem to be a Klon Centaur clone. At least it matches the schematics that are posted online, which is my only reference. I couldn’t see the clipping diodes […]



NPD: Seafoam Chorus
January 18, 2014

New Pedal Day! Keeley Seafoam Chorus More to come as I get some time to play with it.
