The Asheville Music Tools Insert Cable is designed specifially for the ADG-1 Special Edition. The BTPA CA-0678 cable was selected for its braided shielding which adds durability. The Revelation TRS pancake connector and SP400 connectors are both low profile and work perfectly for a pedalboard with tight spaces. The SP400 connectors are labeled with Send and Return. Please note the Send and Return are wired opposite to many others. The Send is wired to the ring and the Return is wired to the tip.
