As BOSS’s first bass multi-effects processor in over five years, you know the
GT-6B is something special. This 24-bit floor-based unit gives bassists
access to Roland’s COSM®Modeling, specially tuned for bass! You get
models of six classic bass amps like “Concert 810,” “Session,” “T.E.,” “Bass
360,” “B Man,” and “Flip Top” — plus speaker cabinets including “8 x 10,”
“4 x 10,” “2 x 15,” and more.

And the effects? Only the best BOSS has to offer, from standards like reverb,
chorus, delay, and flanger to exclusive COSM Overdrive/Distortion Modeling,
Wah Modeling, and new COSM Compression. There’s even a S/PDIF digital
output and Analog Bypass function for pure, unaltered tone. And with cool
performance features like Auto Slap and sound-on-sound looping — plus
fat synth bass sounds with lightning-fast tracking — the GT-6B blows away
the competition.

The GT-6 Guitar Effects Processor is the culmination of over 25 years of BOSS effects know-how. This
floor-based multi-effects processor starts with 30 incredible-sounding COSM amp models — from vintage
classics to modern screamers — then adds new COSM Distortion/Overdrive Pedal Modeling and COSM Wah
Modeling for those classic and modern pedal sounds.

With 340 programs, the GT-6 delivers more of the effects guitarists are looking for — like chorus, delay, reverb,
phasing, flanging, tremolo, pitch shifting, Slicer, Acoustic Simulator, and more — plus new “Uni-V” and
“De-Fretter” effects for phase shifting vibrato effects and fretless sounds. New EZ Tone and Customize features
make dialing in tones easy using the knobs — just like compact pedals! And while it looks good on stage,
the GT-6 also shines in the studio with 24-bit processing and a S/PDIF digital output.

GUITAR MULTIPLE EFFECTS

The ME-50 Guitar Multiple Effects gives guitarists easy access to killer BOSS multi-effects like delay, modulation and
reverb — plus incredible-sounding COSM®overdrive and distortion — without all the menu-surfing. Each effect
section is clearly laid out with three footswitches and knobs for intuitive editing. Other effects include essentials like
analog delay, flanger, phaser, tremolo, Harmonist, Uni-V, and Rotary.

The rugged ME-50 offers easy tonal shaping via its Tone Modify function; select from Preset EQ settings like “Fat,”
“Presence,” and “Acoustic” to change your overall tone. And with dedicated compressor and noise suppressor
algorithms, you always have access to these essential effects. Other conveniences include a chromatic tuner with mute
function, 30 User memory locations for storing your settings and the ability to use battery or AC power. No other
multi-effect processor can match the ME-50’s quality and ease of use.

Killer Tone is Just a Stomp Away…
