  This page collects together just the information you need if you’re intending to build one of the Electric Druid effects pedal/stompbox projects. For each pedal, you only really need the construction guide, which includes the full bill of materials (BOM) and a wiring diagram for the PCB in the enclosure. We also provide a drilling template for your enclosure. Each of these pedals has a separate page about it, usually with a lot more information about the development of… Read more »

FilterFX – 12dB/oct LP/BP/HP LFO filter with 8 waveshapes

Posted by & filed under Stompbox stuff, Wah, Autowah, and Filters.

The FilterFX project uses the Druid STOMPLFO to control a 12dB/oct state variable filter. A state variable filter (SVF) is chosen because this filter design offers highpass, bandpass, and lowpass outputs which gives us the greatest range of different effects. The LFO offers eight waveforms, including two random waveforms (one does those crazy sample-and-hold effects like the Maestro FSH-1). Furthermore, the PCB provides for addition of an expression pedal to allow the filter to be used like a wah pedal… Read more »
