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® Modeling 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 Modeling and Wah Modeling, bass players can get some of their favorite 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. Auto Slap, Looping and More New performance effects include an Auto Slap feature, which creates automatic slap patterns using Preset or User templates, plus sound-on-sound looping for creating loops "on the fly"-even fat synth bass sounds with killer tracking.
