Squareplug SP550-SBK, TRS pancake plug, black finish
The Squareplug SP550-S is the TRS variant of the SP400/SP500 low-profile right angle pancake plug.
Squareplugs are currently the world's smallest solder-type pancake connector, and features a very low foot-print without sacrificing strain relief.
The low-profile of the Square Plug SP550-S allows the connectors to be plugged in directly next to one another, meaning they can be used on pedal switchers and stereo inputs/outputs needing a TRS cable.
The plug is compatible with any 5.8mm cable diameter or less. Mogami W2552 works very well with these plugs.
