SWITCHCRAFT #228 - 1/4" MONO RIGHT ANGLE "PANCAKE" PLUG
MADE IN USA
Used in many combo amps for speaker connections. Also perfect for close quarters pedal-to-pedal connections.
Tech's notes: "These work best with cable that is 5.5mm-6.5mm in diameter. It can work with smaller cable, but you will need to wrap that cable with heatshrink, tape, or something similar for a more snug fit."
