On my headless 6-string I installed it myself, but Tom left room for the control unit when he arranged the knob layout. On the 6-string Anne, there was already enough room, and I installed it myself on that one, too. On the 6-string fretless, there wasn't enough room, but I took away the neck pickup that was originally there, thus eliminating the need for a 4th knob, and made room for the control unit that way (and put in a ramp instead of the neck pickup).
I think that I would have preferred to go with a built-in unit in hindsight, but it's not really a problem... so I won't spend the money swapping either of them out for internals.
I use the GK3 with the Roland GR-20 guitar synthesizer.
I use it quite a bit, in fact.
