"LOOP JACK - The FX loop output allows linking to to other pedals using an optional "Y" cable, with the Guv'nor acting as the master switch for the whole effects chain. The "Y" cable needed is a TRS (tip-ring-sleeve) 1/4" type at one end, splitting into a pair of mono 1/4" cables at the other.
OUTPUT JACK - For the connection of the cable from the pedal to the amplifier input socket. Use a mono 1/4" cable (shielded).
Note: For best results, overdrive pedals should not be connected through the effects loop of your amplifier."

"- On one end is a three-piece plug (stereo plug) that consists of a tip, ring and sleeve. Tip is the most upper part of the plug, sleeve is the lowest part and the ring is the middle.
- On the other end are two normal mono plugs that consists of a tip and a sleeve. One tip goes to the tip of the stereo plug, one tip goes to the ring of the stereo plug and both sleeves go to the sleeve of the stereo plug
- You plug the guitar into the Guv'nor's input, the Y cable in the FX loop (other ends: "In" goes to the input of the to-FX-ed pedal, "Out" goes to the to-FX-ed pedals output) and the output of the Guv' nor goes to the amp"
