The right cable for a dependable BOSS guitar-synth rig on a big stage. The BOSS BGK-30 is the official 30 ft / 9 m cable for the Serial GK digital interface used on BOSS synthesizer and V-Guitar products for guitar and bass. It is for players who connect a GK-5 or GK-5B pickup to a GM-800 or VG-800 and need room to move.
Why customers choose it
Who it is for
Guitarists and bassists using the BOSS Serial GK system – the GK-5 / GK-5B divided pickups with the GM-800 guitar synthesizer or VG-800 V-Guitar processor – on stage, in church bands, or in a studio where the gear sits far from the player.
