I found this about the 13 pin connector assignments, can you trace the wires back from that.

DIN-13 PINOUT
Please find below the pinout protocol for DIN-13 connectors.
Pin 1 = String 1
Pin 2 = String 2
Pin 3 = String 3
Pin 4 = String 4
Pin 5 = String 5
Pin 6 = String 6
Pin 7 = mono guitar signal
Pin 8 = synth volume
Pin 9 = no connection
Pin 10 = switch 1
Pin 11 = switch 2
Pin 12 = +7VDC power
Pin 13 = -7VDC power
Sleeve = Ground

Hello VM,
when I was installed the GK-3 internal into my very new Eric Johnson Strat, I had quite wet fingers!  :-)
What helped me a lot is the vidoe on youtube from graphtech, where they explain their installation!

Specially for the woodwork!

Good Luck!

WOW Sustainiac, $500.00 LABOR!..Maybe I just don't understand what all has to be done, or how long it takes, but that price for labor alone seems awfully high!

If anybody else reading this thread has had their internal Roland electronics professionally installed,
what were your experiences like, and how much were you charged?


I had a Graphtech Floyd Rose bridge and Hexpander installed into one of my "superstrat" guitars (you can read about it here-  http://www.vguitarforums.com/smf/index.php/topic,731.msg12716.html#msg12716). The installation was very similar to the GK installation (same toggle switches and 13 pin connector requirements), so I can lend some direct credance that:

* I originally rolled my eyes at a $500 installation quote but when I actually sat down and did the math it's really not out of line at all- especially if your installer is a well known and experienced luthier.   My luthier charges a flat rate of $70 an hour so...
 
Prep work (making sure that he had all required parts, read the schematics, etc.) and check guitar for any preexisting issues- $35

Gut existing electronics and remove exisiting bridge (probably not necessary with a GK installation)- $35

Mask and route guitar body for the new bridge/pickup, micro switches, and new synth volume pot  (lot's of measuring and marking with a little bit of routing...as my installer pointed out, one slip or mistake and it's a $300 new paint job)-$70

Mask and route body for 13 pin jack -$35

Install new bridge/pickup, switches pot, and 13 pin jack (route for additional wiring between new pickup and contol cavity)- $70

Install PC board in cavity (some sort of custom mounting needs to be made for any installation), wire (remember mag pickups need to be wired in as well) and reassemble everything- $70

Restring and set up guitar-$70

Test, tweak, and troubleshoot (see Elantric's common installation issues and remember that any time your luthier spends on the phone with support is billable time to you)-$105

Parts, misc, and taxes- ~$50

I had new pickups installed and the locking nut repositioned on my guitar as well,  so don't forget to figure in time for additional customizations as well.

* The list of common installation issues that Elantric posted is *dead on*.  My installer ran into several of the exact issues listed despite having done multiple installations in the past.  One other "gotcha" to be on the look out for is that very few installers actually seem to have VG-units on hand in their shops,  so they often have no way of testing installations unless you're willing to leave your VG with them (this was where I was really glad I decided to hang onto my old VG-8).

QUESTION #1. Do i have to connect one of the lugs on the 10K pot to ground?..i was experimenting last night by touching the wire from the middle tap of the 10k pot to all the pins on the underside of the 13 pin jack while being plugged into the VG-99, and i was unable to get it to function.

ANSWER #1.

Yes counterclockwise lug goes to Ground, center lug goes to Pin #9 on the 13 pin.

At the end of the line ,when you connect to the VG-99 Control pedal input,  it must replicate this circuit


QUESTION #2. Which one of these pins in the photo below of the underside of the 13 pin jack is pin 9?, and is soldering the only way to connect to it?

ANSWER #2

Take a paperclip and an ohmmeter and buzz it out  - to verify which pin is "pin #9"


QUESTION #3. Does the 1/4 cable that runs from the pin 9 output of the RMC Fanout box to the VG-99 need to be stereo?

ANSWER #3

Yes - refer to Fanout Box instruction manual

Hey Elantric,

I just thought of something that might make this easier on both of us.

Below is a photo of the type of 10k pot that i am using, along with the Roland electronics.

Where EXACTLY do i connect the wires coming from the pot lugs? (where SPECIFICALLY on the Roland electronics)

I've done all kinds of electrical work on my own guitars over the years, so it would be no problem to connect the 10k pot to a 1/4 stereo jack/cable to mimic the EV-5, but i'm unsure of where to connect the wires to the Roland electronics as the schematic doesn't say which pins are which on the underside of the 13 pin output jack. (which has 14 pins underneath it!)

I thought since you've done this with your guitar(s), that you would share the info with me!  Smiley

Thanks for all your help, and for this wonderful forum, Royce

Buy an ohmeter
learn electronics before you damage something
