About

Connect

GKPX-14 allows you to connect your 13-pin guitar to up to four Guitar Synthesizers (Roland GR-33, GR-55, VG-99, Boss GP-10, SY-1000 etc.)
The 13-pin input is compatible with Roland GC-1 or any other 13-pin GK-3, GK-2 or GK-KIT equipped guitar.

GKPX-14F Subsonic filter

GKPX-14F is the same product but includes also a Subsonic Filter for enhanced tracking with Piezo Guitar pickups (not suitable for GK Bass).

The single Footswitch

The Footswitch will operate various stomp patterns to apply individual VOLUME and S1/S2 control to the output units.

Compact

The GKPX-14 unit does the same work as two Roland US-20 or a Roland GKP-4.
But in a much more compact size.
And if you choose to add the Piezo subsonic filter you get even more features in the same small unit.
