Define a "hybrid" kit?
A hybrid kit could be a drumkit with an acoustic kick and snare, and electronic toms.Or an acoustic kit, but with a trigger on the kick and snare to reinforce them with a triggered sound.
Or, it could be an acousic kit with mesh heads, and triggers so that the "acoustic" drums produce no sound - they just generate a signal for an electronic sound source (such as a Roland TD-8) to use as a trigger pulse. (i.e., This is what is called a "stealth" kit....it looks acoustic, but the sound is electronic.)
