3-position switch that lets you instantly switch between mag/both/acoustic when plugged into the Acousti-Phonic.
(When plugged into the Hexpander MIDI Interface, this same component selects between MIDI/both/guitar, where guitar is whatever's on the Acousti-Phonic's QuickSwitch.)
This mini switch mounts in a 1/4" hole in your pick guard or guitar top.
You may want to add to your installation:
BD-0206-00 Acoustic Volume Pot with Mid/Dark Switch
If you want both of these options with your Acousti-phonic, it's better value to order the Acousti-Phonic Kit for Guitar or the Acousti-Phonic Kit for Bass.
