The Insert Patch Cable is a necessity in this day when stereo pedals are everywhere yet not every builder uses the same connection. For example, when you want to run you Empress Echosystem into a Meris pedal that only has a TRS input, an Insert cable is a necessity. Revelation Cable uses a nickel pancake connector for its TRS and has four options for TS connectors (Revelation pancake; SP400; G&H/BTPA Stubby or SPS4). There are also three cable options. The Mogami dual unbalanced 2528 and the Mogami 2314 are essentially the same cable in a different package. The only difference being the two cables of the 2528 are joined together in a zip cord fashion.
