AMZ Mini Booster SMD
What’s everyone think of SMD? It seems more and more boutique builds are going that route, and with more parts only be available in SMD form, I wonder how long before it’ll be hard to get quality parts in through-hole packages. All that to say, here’s a simple etch-able SMD layout of the AMZ Mini … Read more
AMZ Overdrive Pro
An oldie, but a goodie (I assume–Jack designs good stuff). It’s a unique high gain design with a 3-band EQ. In Jack’s own words: It was made by combining the following circuit fragments: input gain stage is the Muffer, followed by the IC gain stage of the Fat Gnat, a tone control from the Fender … Read more
AMZ Son of Screamer
Where would DIY pedal building be without Jack Orman? Got a request for his Son of Screamer, which is a pretty standard Tube Screamer but with the input and output buffers removed. Pots are board mounted and I added a extra diode in the feedback loop for asymmetrical clipping if you want to go that … Read more
Catalinbread Sagrado Poblano Picoso/AMZ MOSFET Booster
The Catalinbread Sagrado Poblano Picoso is a bass version of Jack Orman’s (AMZ) MOSFET Booster. Really the only difference between the two are a couple cap values. So if you want to build the AMZ version, sub the 470µF cap with a 100µF and the 220nF with a 100nF. Should be a pretty easy fit … Read more
AMZ Dr. Quack
The Dr. Quack is Jack Orman’s improvement on the EHX Dr. Q envelope filter. Basically, there’s an added input buffer to increase the input impedance (which is kinda low in the Dr. Q) and offers better range control. Check out Jack’s blog post on the circuit for more information and a few mods.
