Divided Pickups
To fully harness the potential of V-Guitar technology, you need an instrument equipped with a Divided Pickup. Sometimes referred to as a “hex pickup,” this innovative design produces a separate signal for every string, enabling independent processing of each. While some V-Guitar products allow the use of standard guitar pickups, we strongly recommend the Serial GK system to unlock the full power of the latest V-Guitar features and capabilities.
Divided Pickups have undergone significant advancements over the years. The current Serial GK models include the GK-5 for guitar and the GK-5B for bass, offering cutting-edge performance. There are even pickup installation kits for immaculate customization of six-string guitars, seven-string guitars, and four-, five-, or six-string basses.
Earlier Divided Pickup setups utilized a 13-pin cable system and had a bulkier design, but today’s Serial GK units are significantly more compact and streamlined. Additionally, BOSS provides converters for seamless forward and reverse compatibility between these systems.
The GK-5 and GK-5B feature a standard quarter-inch TRS jack for easy connectivity and a sleek, low-profile design. They can be purchased and installed by the user, but for a more complex installation involving internal Divided Pickup kits, we recommend consulting a professional luthier or technician for optimal results.
