BOSS released GT-1000CORE system program Ver.2.02 in July 2026, according to the update history on the company's support page1. The update applies to the GT-1000CORE, a multi-effects unit in the company's multi-effects pedals line.
Ver.2.02 adds parameters to PLAY OPTION that disable the function that works when two switches are pressed simultaneously1. It also fixes two bugs: noise produced under certain conditions when switching patches without interrupting the sound, and the MANUAL control function failing to work well under certain conditions when assigned to the built-in switches1. BOSS also lists other minor bug fixes1.
For players on older versions, BOSS describes workarounds. The patch-switching noise does not occur when patches are switched with a mute of sound, and the company suggests moving the position of an unused block so that the chain block position does not stay the same in the patches before and after the switch1. For the MANUAL issue, setting ASSIGN SOURCE to a switch other than the built-in switches can avoid it1.
The update is carried out over USB with the unit connected to a Windows or Mac computer1. BOSS instructs users to hold down the [WRITE] button and turn on the power to enter the updater, copy the extracted update files to the root directory of the GT-1000CORE drive, disconnect the cable, and press [WRITE] to start1. The company warns that powering off during the update can leave the unit unable to start in normal operating mode, requiring service1.
To check the installed version, BOSS says to hold down [EXIT] while turning the power on; if the display shows Version 2.02 or later, no update is needed1.
The previous release, Ver.2.01, arrived in March 2026 and removed the polyphonic tuner function1. Ver.2.00, in July 2024, added three BOSS high-gain amp types to AIRD PREAMP, six bass amps, two BOSS distortion types, and three AIRD OUTPUT SELECT models, and added a time setting to the AUTO OFF function1.
