Bring along a fully professional guitar setup without breaking your back; the BOSS GT-100 COSM Amp Effects Processor is a multi-effects unit containing a full library of amplifier and effects models to create big and expansive tones without having to lug a couple of 150 watt full-stacks around.

Advanced COSM (Composite Object Sound Modeling) amps model vintage classics and modern amps that deliver well-known and never-before-heard tones. The effects selection includes overdrives, distortions, mods, delays, reverbs, and more modeled from BOSS and other famous manufacturers. Despite all the advanced functionality available, the BOSS GT-100 has an intuitive user interface with dual screens and 8 knobs, precluding the need for menu-diving for tone adjustments.

For extended real-time control over the GT-100's 400 possible patches (200 presets + 200 user custom patches) extra footswitches or an expression pedal can be added. Use the onboard monophonic Guitar-to-MIDI conversion to drive synths and notation software. Control over MIDI is also available. A USB connection provides a direct digital connection to a computer for direct recording to your DAW and transfer of patches to the BOSS Tone Studio software (Firmware Version 2.0 Required). Patches can be shared with and downloaded from BOSS Tone Central online.
