Unrivalled Sound Quality
When designing the GT-6B, BOSS' primary focus was quality-quality you can hear in every component from its 24-bit converters to its true analog bypass, allowing bass players to switch to the pure tone of their bass guitar when desired. A balanced XLR output and coaxial digital output ensure the highest sound quality when recording, giving the GT-6B a decisive advantage over other bass multi-effects.

COSM® modelling for Bass
Thanks to proprietary COSM technology, the GT-6B can model the sound of six classic bass amps including "Concert 810," "Session," "T.E." "Bass 360," "B Man," and "Flip Top." But amps are only half the story, so the GT-6B also includes several speaker cabinet models like 8 x 10, 4 x 10, 2 x 15 and others. Now you can get great tone direct!

Killer Effects with COSM
The GT-6B features BOSS' finest "bread-and-butter" effects—including chorus, reverb, delay, flanger and more—all tuned for bass guitar. And with COSM Overdrive/Distortion modelling and Wah modelling, bass players can get some of their favourite tones and effects without using amps or noisy stompboxes. The GT-6B also features new COSM Compression, which offers models of several well-known compressors. With all of these amazing COSM effects, bassists can literally just plug in and play.
