Ghielmetti Matrix Pins / Plugs Type 621 Black, Pack of 10.

Used for modular synth patching, also widely used in the A/V and power control industries. These are very high quality product made in Switzerland and they don't come cheap!

Bought these a while ago when I was planning to build a Synthi style patchable synth, but it never happened (and before you ask the Matrixes are long gone) Also selling some red ones on another listing. These are blank open pins, can be fitted with resistors, diodes or shorted depending on your needs.

Please see my other items and Thanks for looking.
