I just picked up a TC Electronic Echobrain. Nice pedal. I have not used delays much in the past, only for Stray Cats Rockabilly stuff. I used to use Dan-Electro pedal, the CoolCatand I don't think I noticed this with that.. But I am somewhat bothered by what I believe is called Self Oscillation sounds that occur at tight delay settings.. I have searched for info on this without knowing how to describe the sound and after a while I lucked onto this video describing it and demonstrating it. Just before this section he tweaks the delay time and gets the pedal to start clicking. That "ticking" sound that happens after each repeat... I kinda hate it.. Is that a quality of certain types of delays? Analog etc... It sounds like an incomplete repeat that is cut short. Is that just the way a Delay Works? Thanks!
