AmericanDJ QTR 1/4-Inch Instrument Cable

The Accu Cable QTR6 is a 6-foot instrument cable terminated with a 1/4-inch mono plug at each end, the run from a guitar, keyboard, or media player to an amplifier or mixer input.

Six feet keeps slack down for a player standing at their own rig or a source sitting on top of the amp, which is where most of these cables actually live. ADJ catalogues it under Audio Signal as part number QTR6.
