Enclosure to intercept the Variax RJ45 signals.

One is for the guitar, the second RJ45 is to connect to a helix or POD xt to provide the power and AES.

Cutting a midi cable in half and making one an IN and the other an OUT allows connection to a standard MIDI interface
 
Wiring up is done as per the description here.
I wired the power and digital audio lines as passthrough
