How to Install the Roland GK-Kit-GT3 Divided Pickup Kit
One weekend I spent a day capturing on video my adventure…..
in modifying my brand new Fender Modern Player Marauder to install the Roland GK-KIT-GT3 permanently, internally in the guitar. Last year I wrote about my first venture into GK land and how I installed the Roland GK-3 external pickup on an Epiphone Dot semi-hollowbody guitar.
Per Roland’s product description:
This kit includes all parts for permanent installation of a GK-3 Divided Pickup into an electric guitar: a GK-3 Divided Pickup, circuit board, switches, power indicator LED, 13-pin connector, wiring and hardware. Professional installation is required.
- Divided guitar pickup for use with Roland V-Guitar System, GR-20 Guitar Synthesizer, or BOSS GK Effect Pedals
- 3-position switching between divided pickup, natural bass pickup, or mix of both
- Mounts on any electric or steel-stringed acoustic guitar
UPDATE: Since the above picture was taken the S1 and S2 buttons have been recessed so they are below the surface of the guitar to avoid accidentally making a change mid performance!
First here is my video….wow, I surprised myself….I am actually getting a little better at camcorder action and iMovie editing….and then I have transcribed below my 40 steps from my spiral notebook to install this unit. Due to YouTube’s rules, I had to split this into two parts to stay under their “10 minute rule”:
Part 1
Part 2
Since this is what I did specifically for my Fender Modern Player Marauder all of the steps might not apply to your guitar if it is not a Marauder or you decide to wire things differently than I did. By the way, there is a great resource on all things related to V-guitar and DIY guitar projects at the V-guitar user forums site at www.vguitarforums.com.

Finally, here is a tune I recorded using the Roland GR-55 for the cello portion and along with a mic’d ukulele. Or Click here to check out my music!
