Love it! I have the THR10 non-"C" version of this amp and often wondered if it's hackable.
I have always been wondering if I could upgrade it to get closer to the THR10.
It's so portable but therefor lacks a couple of knobs. When using the USB connection and some unofficial controller app that I found somewhere, all the knobs were available!
It would be cool if I could just stick some knobs somewhere on the side and make it do more stuff :) But I've also been hoping the connectors for the knobs may just already sit there, unsused.
This encouraged me to finally open it up and check what I can find.
