Is there a difference between the Roland GK-2A and GK-2AH pickups used for MIDI?
The GK-2AH is what Stick Enterprises, Inc installs on their Sticks. I believe the H stands for the “humbucker” version. The pickup is also encased in clear plastic, as opposed to the black casing of the GK-2A. You will also note that the external wiring of the GK-2AH is shortened for a cleaner installation onto a Stick.
