Best Switch for Tap Tempo into pedal jack

[Iggster]

Hey all, I'm wanting to tap in tempo to a T-Rex replica back in the rack. What pedal switch (ie, boss FS???) would you suggest I use to plug into the "pedal jack" in the ground control?

The Expression Pedal ports on the Ground Control Pro use TRS (Stereo) jacks. In order for a switch to successfully work with this setup it must be able to connect the Tip to the Ring in one state, and connect the Tip to the Sleeve in the other state. You have three options for a Tempo Switch... The guys at Mission Engineering offer one that is called the TT-Latching, we can make one in a small "MXR" sized chassis (cost is $50) or we can provide a schematic if you want to make one yourself. Good Luck!
