"This cool effect, originarily intented as a trumpet simulator (the more 
or less known Vox Clyde McCoy), has been made famous by Jimi Hendrix, 
and is a simple bandpass filter with a high Q (a value around 10 seems 
to fit best). The pedal's movement controls the resonance frequency of 
the filter, and ranges from about 500Hz to 4000Hz. That's all"
