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 tweaks and may be built into a Hammond 1590B or similar stomp-box… Read More: JFET guitar/instrument buffer pedal »
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 flow… Read More: Guitar leads, buffers and true bypass »
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 Piezo Preamps are available from the shop here. The… Read More: Unbalanced Piezo Preamp »
Phantom Piezo Preamp Modules are available from the shop here. Sometimes, back-of-the-envelope calculations do not tell the whole story (and neither do simulations). This article is a follow-up to the original article Phantom Piezo Preamp and addresses some errors and misconceptions that have arisen. The Phantom piezo preamp module (available in the shop here) has… Read More: Phantom Piezo Preamp – revisited »
