Barefoot (LDR Volume) Pedal

Barefoot is an idea for a pedal I’m working on, which is a really, really simple concept, and is planned as just a bit of fun. It is a LDR (light dependant resistor) volume pedal, which by the characteristics of the LDR sensor will swell in and out. LDR is by no means a new idea on pedals, Devi Ever uses a LDR on her pedal the Eye Of God/Truly Beautiful Disaster to control feedback in the loop, and many other builders have incorporated them into pedals in some form or another. I remember seeing a schematic for a LDR volume control that had a pot, which controlled a LED, which shone on a LDR changing the output volume. I’m going to just have it in a small window controlling volume on this pedal, so when you cover the sensor the volume will decrease, and when light gets to it will swell back up. The swells are pretty subtle, it isn’t like a Boss Slow Gear or anything like that, but you can defiantly hear them. It isn’t really going to be an exceptionally useful pedal, but it should be fun all the same! In a live situation it could be interesting depending on the lighting, but at the end of the day it is what it is, which is, a bit of a laugh. Plus I had a LDR sensor, enclosure, paint etc all lying around…

I decided on the name Barefoot as it is probably something that will be easier to control in  bare feet (or at least socks!) than it would in whacking great Doc Marts. The artwork is tied into the name Barefoot as the character on the pedal (Kaede Smith) appears in the game Killer 7, where she is referred to throughout by one of the characters as Barefoot. I love the style of the artwork in the game, and Suda51’s philosophy on creating games, so this pedals artwork is in sorts a tribute to that.

Although the pedal has a 9v input it will run passively, the power is just for the LED.
