SquarePlug™ SP500 is the smallest 1/4"  soldered connector on the market. It is 20% smaller than the Switchcraft  228 and projects by only 8.3mm which is much less than any currently  available soldered and solder-less connectors.

What makes SP500 stands out though, is  its ability  [thanks to a super compact design] to be patched into  adjacent and closely–spaced socket configurations [like the ones found  on floor and rack based switching systems] where no other right angled  soldered plug can.

With SquarePlug you get the performance  and reliability of a soldered connector with virtually the same  footprint of a solderless one!

The plug is compatible with any 5.8mm (0.23") cable diameter or less. SP500 is compatible with the following popular switching systems: VoodooLab Pedal Switcher, PX8, PX8 Plus, HEX | RJM PBC, Mini Effect Gizmo | MusicomLab 6M, 62M, 8L, MKIV, MKV | Providence Audio PEC-4V, PEC-2 | IdeaBench Switcheroo | Carl Martin Octaswitch, Octaswitch mkii | Vinteck V8 | Cusack Music: PBT9, PBT6.
