Description
The product that FREE THE TONE has custom-made most often to date is the signal junction box. It's a simple product that connects cables, but countless musicians use it as part of their pedal boards or rack systems. Packed with the know-how we've accumulated over more than 20 years, this product offers the highest sound quality and convenience.

In addition to phone jacks, DIN connectors are also available. The 7-pin DIN connector is compatible with MIDI cables and ARC series LINK connections.


As pedalboards become smaller, there are more cases where effects, tuners, etc. are placed on top of the signal junction box. In response to this, we have made the following specification changes.

1. Terminal name display changed to silk screen printing. In the case of the conventional label specification, if hook-and-loop fastener (Velcro) is attached on top, there is a possibility that the label may come off when attaching or detaching, so we have changed the specification to silk screen printing.


- Wiring between devices is simplified, reducing the time required for setup.
- By connecting via a junction box instead of directly to effects pedals that are lined up in a narrow space on the pedal board, you can reduce damage to cables and plugs.
Depending on where you place this product, either of the INPUT terminals can be used as input.
