Be sure to add me to your favorites list Yamaha Compact Foot Switch / Hi Hat Trigger Pedal for Many DD and YDD Model Digital Drum Pads, Also Use as Start / Stop Trigger for Other Units. This listing is for a Yamaha foot switch / foot pedal, in very lightly used condition. It is very compact with a large center switch. It is used as an on/off switch, a trigger for sequencers / drum machines, and a foot trigger pedal for the Hi-Hat pedal input on several models of Yamaha digital drum pads. The unit has a cable which connects to a 1/4" inch phone plug type connection. Many of these models that take a pedal have an input that takes this type plug, but there are some that cannot accept it, please make sure yours does before you get it, or ask me for some help if need be. If your model has a trigger input that takes the 1/4" inch phone plug, then this is exactly what you need for use as a Hi-Hat trigger on your DD or YDD model Digital Drum Pads, and other uses as well. This can have other uses as well. I use an identical one to trigger Start / Stop and Pattern Changes with my Yamaha QY700 sequencer. I have a couple of these available at this time.
