The tb8 was designed to be installed in either the up or the down position. Performance will not be affected.

Only one mounting screw is necessary because the natural curvature of the drum acts as a lock washer to prevent unwanted rotation. The cone should rest approx 1/32- 1/16” above the bearing drum edge (slight pressure up against the bottom of the mesh head). Use 2 wrenches to tighten pedestal hardware.

The pedestal and cone can be positioned anywhere within the tb8 bracket slot. Most drummers prefer center mounting for positional drumming.

TB8 Installation Guide
1) Remove acoustic drum head (some have installed mesh on one side and acoustic head on other for flip-n-play advantage).
2. Locate the tb8 close to the vent hole. Remove the drum lug screw, set Tb8 in place, square up and tighten lug screw. Only one screw is needed as the natural drum shell curvature acts as a lock washer. Snug down tight.
Slide trigger assembly to desired location along the bracket. Many prefer center mounting. Carefully set trigger height to 1/32- 1/16” above the bearing edge. In other words, just slightly higher than the drum head for gentle contact with mesh head. Too much pressure desensitizes response. Too little pressure causes double triggering. Tighten both nuts using wrenches.
Remove vent grommet. Vent grommets are either pressed in or threaded. Insert proprietary rear entry 1/4" jack. Once jack is installed, tighten each nut firmly. Now install your preferred mesh head.
Bass drum TB8 trigger should be placed 5" away (as shown in picture) from the beater impact position. This is due to heavy beater impact demand. Only one trigger is needed for double bass.
