The FilterFX project is a contolled 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).

This kit is a creation by electricdruid.net in cooperation with Musikding.de. If you have any problem with the content of the kits like missing or wrong parts, please contact Musikding (Klaus) at email@example.com. For any technical problem relating to building this project, please contact Tom at www.electricdruid.net
Here´s the parts list: Parts List (BOM)
This kit contains all parts you need to build a fully functional effect pedal. Not included in the kit, but also good to have:
- Aluminium enclosure: select one from top
- 9V DC power supply
- 4 nice knobs for the potentiometer, up to 20mm diameter and for 6.3mm shafts
- Decal, transfer or transparent sheets for labeling
