This is really just a quick link share for a friend— I have nothing to say on the subject of electronics, other than to give the reasons I don't use them. But for a couple of years in the 90's I did work for Mike Snyder, building drum triggers, when he still had his company Trigger Perfect. He was a studio drummer in LA in the 80's, and came up with the first decent trigger, and no one knows more about the subject than him. There tends to be a lot of confusion and frustration among drummers about this, due to lack of education, so here, from Mike and Drum! Magazine, is the latest, best information on triggering electronic sounds from an acoustic drum.
