You may also like to add "How to Tone-mod an analog delay pedal" -- i.e. to make any analog delay pedal more versatile in terms of echo-repeat tone/damping (making repeats and self-osciilations with higher or lower frequencies).

Example: Modding an Ibanez, Boss, or DOD analog delay for tone/repeat damping control, or component mod to allow for such capabilities.

Like, think about David Gilmour's last few guitar riffs in the track "Dramatic Theme" on Pink Floyd's album "More:Soundtrack from the Motion Picture". The echo repeats have a higher-frequency tones and overtones (although he used a Binson II Echo unit).
