After two and a half years and thousands of Phantom Piezo Preamps sold, we finally ran out of 2SK596S-C JFETs (which have been discontinued for some time by On-Semi). Going forward, the best option is the Fairchild PF5102 (now also an On-Semi product). We have slightly redesigned the Phantom Piezo Preamp PCB to allow […]
Update: Kits now available in the shop here.
Update: Carsten posted a YouTube video here.
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 […]
Updated – see below for information on improving the design to lower the output impedance.
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 […]
