Dual Trigger System (E-drums)

The Torque Trigger is the most accurate trigger system for acoustic to E-drum conversions. Watch this video to see how to build an e-drum pad.

We install the system inside this 13” tom shell. Both heads and rims get removed, before unscrewing the upper lug screws. These extendable spacer bolts get applied as several lug windings require different lengths. An additional washer is needed before installing. These extension bolts are used to build the matching torque. In this case we need 3 of them. Bigger shells require more, smaller shells less. Holding up the first bold against the others is important to not destroy the lug winding. The inner lug windings are really short in this case, we need to use the counter nut to tighten them. This shell does only have 6 lugs, others have 8. The trigger system can be used for both constellations. The trigger body is mounted by short M4 screws including washers. The slotted holes of the applied metal angles make the system fit into any shell. The angle screws are still loose to enable a sliding movement. This metal angle can be mounted from above or below, depending on the required height. The 6 screws get tightened as soon as the system is in place.
The other 6 angle screws get tightened, to finally anchor the system. The next step is setting up the height of the trigger cone, which should be 1,5 mm higher than the shells bearing edge. The counter nuts of the 3 elevation screws get untightened with a socket wrench. The trigger cone height can be adjusted by turning all 3 screws. The indicator shows that the correct height is set. The counter nuts get tightened before checking the cone height again.
We use a part of jack plug cable, a socket terminal and a 3.5mm jack cable piece to connect the trigger. The terminal is screwed to one of the lug screws. The stereo jack plug cable fits trough a small air vent and gets applied to the terminal. The other piece is a headphone cable that can be plugged into the systems integrated jack plug. Both cables get screwed to the socket terminal. 2 Cable ties prevent the cable from slagging around. And now we are done with the system setup. There are many other cables that can be used, this is kind of a DIY solution. We use a 2 ply drum-tec Series Mesh Head for the top, and a single ply resonant head for bottom of the shell. The result is a fully converted 13” tom. The conversion can be reverted at anytime, nothing at the shell is getting damaged.
The trigger system delivers the most accurate head and rim triggering result. The setup is simple as only some slight changes are necessary.

The torque trigger can be applied in all shell sizes from 8-18”. The system is really solid, even in a 16” shell with only 6 instead of 8 torques. The center mounted cone enables positional sensing and the rim trigger ensures a consistent rim triggering from every spot of the rim. The system is also really flat, light weight and does not take too much space.
