Update: Kits available in the shop here.
Following on from our articles on the Unbalanced piezo preamp and Guitar leads, buffers and true bypass we present a project to build your own JFET buffer pedal. The circuit is essentially the same as in the unbalanced piezo preamp with a few […]
I had an enquiry about using the new unbalanced piezo preamp to buffer a guitar lead and I thought I would do a write-up on the low-down of buffering and bypassing.
The basics of impedance and the effect of long guitar cables.
When we talk about impedance, we are talking about resistance to the […]
Update: Modules are available in the shop here now.
I finally decided to retire the Altoids Piezo Preamp Kit and Altoids Piezo DI kit projects from the shop; I received good feedback from customers – but not enough people bought them. Fully built and tested Altoids […]

Update: Phantom Piezo Preamp modules are available for purchase in the shop here.
A few years ago, Alex Rice put a design up on the internet for a phantom-powered JFET piezo preamp. Here’s the schematic of the original design as […]
