Hello,
I've got an unused GTM6+Pedal board+Hex PU still in my stock (15€ all and never installed on my guitar what a shame but for my excuses i've no time) .... Recently i've bough a VG8 without GK and i need to buy one (GK2/3) to drive the VG.
Is there any way to recycle my old shadow Hex PU (it's simple TRS jack output) to connect it to the Roland VG system ?

Thanks

VG99 works with 1/4" but not all features

The Shadow  GTM6 system employed an onboard  analog Multiplexer,  to send all 6 string signals over one TRS 1/4" phone plug connection. It was a proprietary system that relied on the Rack Mount Shadow/Ovation/Takamine /Charvel GT6M unit to decode these multiplexed signals. Sad to say it does not "play well" interfacing with other Guitar Synth systems.

Some trivia - The recent Tronical/Echo Audio designed Gibson Dark Fire/DuskTiger/LP Limited and RIP (Robot Interface Pack)  employ a similar analog multiplexing scheme  - but (sadly) the Shadow GT6M
signals remain incompatible with those units as well.


====A similar analog MUX implementation was employed by German company Shadow in the 1980's - whose technology was marketed by Kaman Music with MIDI Takamini and Ovation and Charvel MIDI guitars,   25 years ago

MIDI guitar pioneer Shadow's first offering was the rack-mounted GTM-6 guitar-to-MIDI converter and companion hex pickup. Kaman briefly distributed this system, and offered four acoustic guitars--Ovation and Takamine, steel-string and nylon-string-- with Shadow hex pickups built in. To the best of my knowledge, these were the first nylon-string MIDI guitars in the world. An electric guitar version of the GTM-6 was sold with the Charvel nameplate.

I had a Shadow GTM6 after my first Roland G700 / 707 - its tracked quite a bit quicker at the time - oddly a later G707 / 700 set up had some years later was much better so I guess roland did a firmware update.
Ironically the pickup in for the GTM6 died and that was the end of that at the time.

Elantric, I was wondering if you know, has anyone ever tried using one of these Shadow systems with a Passac Sentient Six? I'm looking for a guitar to interface with an inexpensive Sentient Six controller I came across.

I understand this system is compatible with the Shadow GTM6
