The Boss GP-20 Guitar Amp Processor is a compact and powerful amp modeling unit, delivering a wide range of authentic amplifier tones with the famous Boss COSM technology. Known as part of the "Amp Factory" series, the GP-20 offers 22 detailed amplifier models, covering everything from pristine clean sounds to classic crunch and high-gain distortion.

The GP-20 allows for simple switching between Manual Mode and Memory Mode, giving players the choice of real-time control or quick access to stored presets. Tone shaping is easy with dedicated knobs for Gain, Bass, Middle, Treble, Presence, and Master Volume, just like on a real amplifier. Additionally, the GP-20 features built-in speaker cabinet emulation, making it perfect for direct recording or live performances without the need for a mic'd amp.

Durably built in Boss’s classic rugged housing and equipped with both analog and digital outputs, the GP-20 is ideal for players who need professional amp tones in a portable format. Whether used live, in the studio, or for practice, the GP-20 offers versatile, high-quality sound with simple operation.

Fully tested and in excellent working condition. A fantastic tool for guitarists seeking a reliable and powerful amp modeling solution.
