GIG HH Gig HH Pedal with Open/Close control Features Polarity switch ensures use with any current drum module Works as basic hi-hat or patch switch Full-sized foot plate Super quick response *Requires Stereo Cable not included **Note: the new TD-9 and TD-4 has a mono cable for the hi hat controller so this pedal will not work with those modules as is. However, if you tell us you have one of those modules when you order we can modify the pedal so that it will work, at no cost to you, but you must tell us before we ship. If you upgrade your module and all of a sudden your hat pedal quits working this is why and for a small $15 fee plus S&H we are happy to modify your pedal so that it will work with these modules.
