This is just a kicktrigger for kickdrum... based in Raspolzio's, but improved so the force in the kickdrum ring is made in an anchor and with jack output to make it cheaper and jack-jack module prepared.

I'll upload some real pictures of the printed working like a charm in my daily basis drumkit. With some 2 mm. pading between piezzo and drumhead it's as sensitive as the roland one.

Any comments or upgrades I'll be glad to implement them.

Cheers
