Casio MG510 - Roland GK Conversion Chapter 1

The time has come to do drastic surgery on the non-functioning Casio MIDI guitar. While the 1990s output of the Fuji-Gen Gakki factory has superb build quality, I've never been a fan of the Japanese pickups. I happen to have a nice set of DiMarzio noiseless single coils that would suit this guitar very nicely and a Roland GK kit so let's get to work ripping out the old electronics ...

The MIDI control panel isn't entirely suited to the GK controls so I've rattled off a PCB design with a GK volume control, momentary up/down program change switch and a GK/guitar/both selector.

Custom pickguard by local builder Tiny Tone is a hybrid of the old Casio version and a US Stratocaster with three single coils instead of the Casio HSS layout. The MIDI pickup isn't compatible with the GK board so the bridge cutout is Stratocaster style.

I've installed a four-pole double wafer switch as I want this guitar to have my special custom switching.

So that's all the best Stratocaster sounds plus the Telecaster inbetween sound. The noiseless pickups should be perfect for this as there's no problem with not having RWRP in some combinations.

Next job will be drilling the pickguard for the GK pickup.

I've routed a lot of wood away around the bridge and I'll be using a pickguard from another project as a drilling template. This is an after market pickguard for a Fender Roland Ready Stratocaster and the GK pickup holes line up exactly with the Roland unit.
