YouTube video of operation and unit: e-drums hi hat drop clutch Randy: https://youtu.be/zZPzXnXR_8Y
Electronic drums hi hat drop clutch and top cymbal adjuster. RandyJazz.com/Randy $50 or make an offer. It takes me about an hour to drill holes in box, slide tie straps through, wire and solder components then test and then off to the post office.
I built and successfully tested a drop clutch and rheostat to adjust top cymbal height of Electronic Drums Hi Hat.
For use with double bass drum pedals.
It is a TRS (3 wire "stereo") 1/4 inch connection that plugs in between electronic drum hi hat pedal and sound module.
Toggle switch ON to ON one way normal uninterrupted connection like it doesn't exist, toggle interrupts circuit and sends cymbal position signal to rheostat bypassing pedal, immediate upon toggle then top cymbal moves to rheostat setting (if rheostat set at 0 ohms a drop clutch chick sound (cymbals closed)). When you turn rheostat knob the top cymbal "position" moves through sloshy to wide open hi hat (just like if you controlled position with your foot).
Working awesome on my Simmons SD600 drum kit.
