Roland GK-3

The pickup is very light (you will not feel any difference in weight of your guitar) and easy to install even though it does look complicated at the beginning. You will find in the package more than enough accessories to attach the pickup to almost any sort of guitar without drilling or any sort of modification. The sticky tapes are very good and once you attach the pickup it will never go anywhere unless you decide to remove it or you are not really gentle in handling a guitar.

Few things could be improved and I am surprised that the pickup has not been redesigned at least once in all these years. The radius is a bit limited. You can increase or decrease it but if you have a guitar neck that has a small radius or no radius, you might find the pickup not so suitable as it has to be positioned very close to the strings. However, you could still solve that problem by adjusting the sensitivity of all six individual pickups in the setup of your Roland synth device. Also, if you have a guitar with a space between the bridge pickup and the bridge less than 8mm, you will not be able to attach the pickup.

To use guitar synthesizers such as Roland's newer GR series or VG series this pickup is probably the only way to go and it does the job pretty well.

You plug this to your guitar, connect it to GR-55, then you have a whole lot of sounds and Synth under your finger tips. However, this comes at few cons:
- It does not look very pretty on your guitar
- it is not the easiest to plug, adjust and setup onto your guitar
- Needs a particular cable with 9 pins to plug to the GR-55

However ,huge benefits:
- You can switch between synth and guitar sound or Mix them
- You can control the volume of your Synth
- Switch sound banks without having to touch the GR-55

The GR-55 is a great unit by itself, and the GK-3 is the only way to connect your guitar and it works perfectly and as expected.
