I have spent the night trying to find resources that show how various guitar effect pedals mathematically change the sound of the notes being played. I have unfortunately come up with nothing. If you have any idea how the various effects used for guitars can be broken down into mathematical models, or know of a resource already available, please let me know, thank you.

I hope you find these resources helpful.

signal processing

flanger schematics

well, there are many types of guitar effects and many ways to implement each effect, either with analog circuitry or in the digital realm. What effect in particular were you trying to model? A great place to start would be to develop a simple EQ or filter effect.

Thanks for the replies everyone, i''ll take a good look at those links. I''m thinking of doing a Wah-wah effect first, seems to be one of the most popular.

Which effect do you mean with wahwah? If it is the one I think you mean, then it isn''t an effect, it''s a handle on the guitar, that unbends(is this english) the strings a bit

A wah-wah is an effect pedal - you''re thinking of the whammy bar or tremolo bar on the guitar. What a wah-wah is is basically a parametric eq with a fixed Q and boost/cut and the frequency varies as you move the pedal from toe-up to toe-down.

You can also get the wah-wah effect from inhaling whip-it gas.

so it's like a phaser, that you can control yourself
