On Trigger Bass Drum Trigger Jack

Once you have found the sweet spot adjusting them they are very sensitive and very accurate. I play 280bpm 16th notes and they trigger perfectly. I wish they had two holes for screwing. They tend to shift while playing, fixed with some tape. I also wish they had a different mechanism for adjusting the hight of the sensors. I do not know how long the metal holding the sensors can last if you have to bend them for every show you play. They should be adjustable by a step- mechanism similar to plastic straps. Hence 4 stars instead of 5.
