The relay bypass is back in stock and I made a couple of changes to the design before reordering the boards. It now has a jumper that allows you to select whether the bypass powers up with the effect either on or off. Previously it always started with the effect off, but now you have a choice of how to build it. I also have a limited number of soft touch momentary switches available for purchase with this project.
Order the AMZ Relay Bypass.
Parts Kit now available
The AMZ Tweed Stack is a revised and improved version of the Dual Mini-Booster
and Booster 2.5
designs from the late 1990s. It uses four jfet transistors in a high gain configuartion to provide a smooth overdrive tone like a vintage stack driven to its limits.
