This is an unlatch-type foot controller for effects pedals and guitar amplifiers. It's a medium-sized type using a Takachi TD7-10-3 enclosure. It has two systems, A and B. Each system has two footswitches and two jacks, TRS and TS. No power supply is needed; it can be used as is. You can switch between NO (Normally Open) and NC (Normally Closed) contacts with an internal switch to match the equipment you are connecting. The momentary switches used are the click-in type. They are not the soft-touch type. The case has a semi-mirror finish. Takachi TD series enclosures may have scratches or dents in their original state. Please note that these original imperfections may remain on the finished product. When using a daisy chain DC cable, please be careful not to touch the case.
