BOSS GP-10 Guitar Processor without GK-3 Pickup

Boss GP-10 Guitar Processor is available both with or without the Roland GK-3 Divided Pickup. The GP-10 becomes an enormously powerful creative tool that expands your production capabilities beyond any standard guitar processor when you use a GK-equipped guitar.

When you record unprocessed sounds in this way, you can re-amp the tracks through the GP-10’s amps, and “re-guitar” as well, using the GP-10’s instrument modelling to change the sound to anything you want after the fact! The guitar-to-MIDI function allows you to stretch your creativity even further, using your guitar to play soft synths, capture MIDI sequences, and input MIDI data into notation software on your computer.

You can freely download BOSS TONE STUDIO software and it lets you edit and organize your GP-10 patches on your computer. The software also provides direct access via USB to the BOSS TONE CENTRAL website, where you can download a growing selection of free patches directly into the GP-10.


Instant access to down tunings, open tunings, 12-string sounds, and your own custom tunings

Instrument modeling powered by COSM technology, including conventional electric, acoustic, and bass guitars, plus sitar, banjo, fretless guitar, and others
