Our recent new member "mitsubamushi" is from Japan and has created a DIY test board for exploring Roland GK-3 interface.
He's a clever guyhttp://www.geocities.jp/mitsuba64/gk/iroiro.htmlhttp://mitsubamushi.yana.jp/

-GK Snooper 2004/06/12 Symbol
GK Snooper ... it Takagi Mr. GK Vara Box You experimental tool was created for verification when making.
Useful things that can be input to and output from the yo like each line has been in the middle branch of the input and output of the 13pin.
In other words, play various input and output of the VG of ... GK (^ ^)
Currently, the borrowing during the courtesy of Mr. Takagi.
I am allowed to entertain various <(__)>
Introduction Since I had also authorized the publication.
Circuit diagram had you sent from Takagi. Do not are you want contact with the Tap terminal by branching between To VG and To GK of DIN 13Pin.
I see from above. Height about 4cm in length and breadth as the size 10cm.
I see from DIN 13pin terminal side. Foundation Na are you a two-layer structure.
Feel the challenge of GK work up privately were not we implement to the base of DIN 13pin terminal.
To're overcome by means legitimate user creates a dedicated base it head to decrease the <(__)>
The back like this. Simple (^ ^)
The contents of GK wiring is written in each Tap terminal.
No. 1 pin = 1 string from lower left, and the second pin = 2 string, third string pin = 3, No. 4 pin = 4 string, fifth string pin = 5, No. 6 pin = 6 string, seventh pin = Normal guitar pickup.
No. 8 pin = GK volume from the upper left, No. 9 pin = no connection, No. 10 pin = S1 SW, 11 number pin = S2 SW.
Grand 13th pin and 12th pin = +7 V, =-7V from the right on.
Expansion of Tap terminal. Na its over he is used to hook the probe of the oscilloscope.
This input and output wiring that I have prepared. Pin female pin that you have processed the surplus.
Do not are you using Hook to the Tap terminal by bending the ends of the wire.
plans to make the wiring of small alligator clip expression Izure.
Like this when using. Usage Notes I wonder if that place you do not want to stimulate the terminal of the power supply to ... accidentally?
• 1st string (high E) Signal Tap from GK 2004/06/12
Accessory you have decided to produce it is inspired by the GK Snooper above.
I just wire the pin terminal to terminal 1 of the string for GK.
It's simple but quite useful (^ ^)
1 string you are back. Foreground terminal conversion of standard phone and pin.
· Ver.2 1 string you mentioned 2007/02/24
The expansion the S1/S2 SW terminal to one string you above!
Now to Yo can manipulate the S1/S2 SW outside foot SW!! (Laughs)
It's easy, but also this quite useful (^ ^)
Terminal has been increased one per string Kimi why.

More cleverness too!
Using the same cable created above, here he is using a VG-8 with a Normal Guitar to feed pin #1 on the GK-13 Input, and has added two footswitches for remote GK "S1" and "S2" .
Also these help add new expression on Bass.
