Also, due to being self-painted, there may be uneven paint, lumps, and chips. There are stereo jacks in two places, top and bottom. When the foot switch is viewed in a mountain shape, the signals are R, T, and T+R from left to right. If you connect a TRS cable to the stereo jack, you can use it as a compatible product for ONE CONTROL AUX switch, Digitech FS-3X, and TC HELICON Switch 3. Since it is passive, no power is required. Only the switch at the apex T (corresponding to the tip) of the triangle has a click feel. The two foot switches corresponding to R and R+T are soft type without a click feel. How about using it as an expansion switch for DIGITECH's WHAMMY DT, TRIO, EVENTIDE H9, TC's NOVA SYSTEM, etc.? It cannot be used as a latch or alternate switch.
