DUO Jumper Settings
The DUO has “jumper blocks” on the circuit board that are used to configure the behavior of the strummer. There are basically two options:
Configure the DUO so each of the 2 strum bars activate the up or down switches in the same direction. This means when you strum down on either strum bar it will activate the “down” strum.
Configure the DUO so the strum bars activate the switches in opposite directions. This means that if you strum down on both strum bars at the same time, one will activate the “down” strum, the other will activate the “up” strum.
