RTB-BD bass drum trigger system (M4)


Professional bass drum trigger system for the installation into acoustic drums (conversion to electronic drums)


Very easy to install by using two opposing lugs. No drilling required!


Our RTB bass drum trigger system is continuously adjustable to the inside diameter of the drum shell and is form-fitting


Height adjustable by slotted holes


Fits into almost any drum with suitable diameter and an even number of lugs per batter side mounted with M4 screws



Included accessories:


M4 mounting screws, washers and lock washers






The terms M4 and M5 refer to the diameter of the threads of the screws that attach the lugs to the drum shell. M means metric.

M4 = diameter of 4 mm


To determine if you need the M4 or M5 version, you can measure the diameter of one of the attachment screws of the tuning lugs with a sliding caliper.


If a reinforcing fin of a metal shell or a reinforcing ring of a wooden shell projects inward the drum shell, our trigger systems may not fit without the spacer kit or a customization. Please ask us for a solution if your drum shells are designed that way.
