We have had a few enquiries about using the true bypass relay board with the control switch remote from the board itself (original article here) (kits available in the shop here). We should emphasise that as it stands, the true bypass board is designed for the ‘Stomp Here’ switch to be […]
We have had enquiries about adding volume and tone controls to the Unbalanced Piezo Preamp (available in the shop here). The PCB was not designed for the addition of these controls, so this article represents something of a hack.
Here’s the schematic for the design as it stands:
The purpose of R4 […]
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 tweaks […]
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 available in the shop now.
The Phantom Piezo Preamp Module has been a great success and has sold very well. […]

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.
Update: reStomp re-ampers available for sale in the shop.
Back in 2012, I wrote about re-amping and offered a design for a transformer-coupled interface between balanced-line output from a professional recording device and the unbalanced and lower-voltage input to a guitar amplifier. If you’re not familiar with re-amping, the idea is that […]
In the first part of this series, we introduced the idea of power control separate from the dimmer system and gave an overview of different ways we can manage switching of power to installed appliances. In this second part, we will look at remote-control schemas for independent contactors.
One Big Relay
So, the first option […]
In my introduction to theatrical lighting systems I considered the many and varied lighting installations you might find in a performance venue and talked about independent power control which we will discuss further here.
In days gone by, practically all of the performance luminaires in a theatrical installation would use filament lamps and be […]
There are many different aspects of lighting in a public space – so many in fact that even seasoned technical crew can be confused. This article offers and introduction to the different lighting systems you might find in a performance environment.
Consider a traditional small theatrical venue. The venue has public spaces and non-public spaces. […]
