Square Plug

The Amazing Square Plug from France 

SP400 is the lowest profile 1/4" metal plug made to date (20% smaller than the traditional Switchcraft 228 pancake design). With a thickness of less than 8.5mm SP400 projects even less than any solderless connector currently available.

 What makes SP400 stands out though, is its ability to be patched into adjacent and closely–spaced socket configurations [like the ones found on floor and rack based switching systems] where no other flat right angled soldered plug can.


With the SP400 you get the performance and reliability of a soldered connector with virtually the same footprint of a solderless one!

→ Super flexible, small diameter [4mm / 0.155"] Mogami 2314 cable for precise cable routing
→ Low noise, low capacitance [33pF/ft / 110pF/m, at 1kHz, 20degC; rating: 60degC, 30V] for excellent signal transfer
→ Ultra–low–profile connector [measures only 8.3mm / 0.326" x 17mm / 0.67" x 28mm / 1.10"] for highest packing density
→ Serviceable, all–metal plug designed to snug–fit smaller diameter cables for optimum strain relief and improved emi protection
→ 2 solder tabs for quick and easy soldering/desoldering
→ Insulation sheet to prevent hot and ground signals from shorting

SP400 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 [Not Compatible with The GigRig G2 and Boss ES5/8]
