I've been enjoying the Intrigg's I picked up a few months back. Installed them in my ae converted Sonor kit. I did not prefer cutting small holes in the heads, for the cables, so had my local shop make jacks and mount in the shells. We left the sound holes as they were. On this particular kit, it doesn't bother me to have drilled them. The jacks look and work great. My second kit is a custom Ludwig. I'm not quite sure how I'm gonna trigger it yet. Highly reluctant to drill it, even if just enlarging the vent holes. I have Roland external triggers, which also work well, but are not nearly as practical when I'm moving the kit gig to gig all the time. The intriggs are ultra practical in terms of mobility. They work great so far.
Thinking out loud here, I used to have May Internal Mic's on one kit. They were very thoughtfully designed. The mic and jack came in two parts, and were designed to use existing holes, with no drilling. The jack end had plastic washers and was held in via threads to the air vent. The cable went from the jack to the mic, and had 3 quick connectors. No cutting, drilling or soldering required. Could you do something like this Triggera?
