As part of a series of up-and-coming BuildBrighton workshops, and in preparation for this year’s Mini Maker Faire we’re busy putting together some simple effects “pedals” that can be put together inside a guitar, to provide onboard electronics.
(as ever, print onto A4 at 100% no scaling for a press-n-peel/toner-transfer-ready image for etching your own)
The beauty of this simple design is that it uses a single 500K linear potentiometer to achieve the wah-wah sound. Which means we can do a lot with this design when it comes to “hacking” up our guitars later. For example, it could be replaced with a digital pot and hooked up to a microcontroller (such as a PIC or Arduino) for all kinds of funky fun!
