GT SERIES

Flagship Multi-Effects Floor Processor

■ Pro Features

The GT-6B is a pro-caliber floor-based processor for bass, with

COSM Bass Amp Modeling, modeled compression, plus other

“must-have” effects such as COSM overdrive/distortion, COSM

wah, and reverb/delay. There’s also a true analog bypass, and

XLR and digital outputs with 24-bit converters for recording

applications, providing uncompromised sound quality.

■ COSM Bass Amp Models

The GT-6B provides six authentic COSM bass amp models,

recreating the tone and characteristics of some of the greatest

bass amps and speaker cabinets in history. Why settle for just

one bass amp sound when you can have the power of six

classics in one convenient box?

■ Bass Effects with COSM modeling

In addition to its amazing amp models, the GT-6B provides a

world-class lineup of effects, including COSM-powered

compression effects modeled after four famous compressors.

Other effects include Auto Slap, sound-on-sound looping, and

BOSS's best synth-bass sounds with incredible tracking.

■ Versatile Performance Controls

Pilot the GT-6B with ease and enjoyment, thanks to its friendly,

ultra-intuitive interface with analog-style knobs. Inject extra

color and tonal animation into your performances with the

GT-6B’s built-in expression and control pedals.

■ Dual COSM Amps

Feel the power of the GT-8’s dual COSM amp modeling engines.

Explore new sonic dimensions by combining two amp models,

or by switching between them during performance. Tap into the

expressive Dynamic mode, where two channels can be

controlled based on picking strength. Transition smoothly from

clean to mean by simply picking harder or softer.

■ Solo Switch

Each of the GT-8’s 46 COSM amp models contains a specially

programmed variation that’s optimized for soloing. Simply click

the Solo switch to activate the lead tone, and off you go — it’s

like having a separate solo channel on every COSM amp!

■ Extreme Effects

Forty-four effects categories are built into the GT-8. Up to 13

effect blocks can be used simultaneously to create complex

textures and routings. All of your FX bases are covered —

compressors, reverbs, choruses, EQs, COSM-modeled wahs,

and much more. There are 200 preset patches included, plus

140 user patches for storing your custom amp/effects creations.

■ Connectivity

The GT-8 is stocked with enough I/O options

to satisfy even the most demanding pro. In

addition to its stereo analog outs, the GT-8

offers a 24-bit coaxial output for ultra-clean

digital transfer, an Amp Control jack for

switching between two amp channels on an

external amp, an external expression/control

pedal input, effects send and returns, MIDI in

and out, and a headphone output.

■ Flexible FX Routing

Another area where the GT-8 stomps the competition is in its

powerful effects routing. Internally, the 13 FX blocks can be

configured in any order you desire (for example, you can freely

assign an equalizer after a distortion effect or before it). And if

you’d care to take your tone “outside the box” and incorporate

some external effects into the GT-8’s signal path, you can do so

with the Ext Loop send and return. Flexibility in routing is the

name of the game.

Ultra-Flexible Effects Chain

Having the freedom to configure the effects chain in any order you wish is one of

the keys to success when using multi-effects. A sound can be wildly different if

an equalizer is used before a distortion, or after, for example. The GT-series

proudly provides complete freedom over the preamp and effects chain routing.
