Pin-7 Output Harness - for Hexpander-only installations

If you are installing the Hexpander without the Acousti-phonic, you may want to add this optional pin-7 wiring harness so that your guitar's mag and/or acoustic signal goes down the 13-pin MIDI cable and out the back of the converter. That way, you don't need a 1/4" cable plugged into the guitar.

Most MIDI converters have two 1/4" outputs on the back -- one for MIDI, and one for this pin-7 signal.

The Pin-7 Output Harness is required if you're installing the Hexpander without the Acousti-Phonic, and are adding the QuickSwitch. It enables the QuickSwitch to control the mag output on the 1/4" jack. Otherwise, the Hexpander and the mags exist as two separate systems. The Pin-7 Output Harness links the two pickup systems in the absence of the Acousti-Phonic.

The 1/4" output jack on your guitar will remain unchanged, and you can use it with a 1/4" patch cord if you just want to play your mags through a guitar amp. Overview of Hexpander output options (PDF)

Note that the acoustic signal on pin-7 of the 13-pin jack is the raw piezo signal, which requires post-processing outside the guitar to make it sound like an acoustic guitar. For realistic, studio-quality acoustic guitar sound from your electric guitar, install the Acousti-phonic.

The Acousti-phonic, if you're installing that too, provides this same feature and makes the pin-7 harness unnecessary.
