Light Affected Tone Pedal Experiment

Description

This is an experiment for a guitar effect pedal whose tone is affected by light intensity and flash.

The tone is separated into a high and low tone and both tones are independently changed at the rate set by the tone intensity and tone flash knobs.

 

 

For example, in the above video the low pitch of the guitar was set to oscillate in value at a fast rate and the high pitch of the guitar was set to oscillate in value at a slower rate. The lights visually show the rate of change of the tone. Noise needs to be fixed in prototype, but otherwise the pedal does what it should.

 

It works similarly to an automatic wah pedal but with finer control on low and high tones and it has a bandpass filter.

The web simulation below is just an experiment using a digital prototype of the actual product to get feedback and opinions.

The real pedal that uses an analog circuit for tone manipulation is much better.

Try it out! Let me know in the comments down below or by email( through CONTACT page) what can be done to improve the pedal.

 

Special note: Currently, the pedal circuit is being redesigned to remove the pop noises. Otherwise, it does what it is stated above.

Also the analog control circuit is being redesigned to include a starting value control for low tone and high.
