Main Features

Highly Evolved COSM Amp/Speakers
The GT-8 includes amp/speaker systems that can be used simultaneously, utilizing COSM amp/speakers featuring 46
different amp types, including newly modeled amps. You can combine amps flexibly in a variety of ways; for example, by
mixing two amps together or setting them up in a stereo arrangement. What's more, you can customize the amp and speaker
combinations, giving you the freedom to create your own original amp types.
A Variety of COSM Effects
The GT-8 features a wide variety of newly developed effects including "stereo dual delay," "spring & modulation reverb,"
"sitar simulator," "wave synth," and more. Making full use of BOSS's superior guitar effects technology, this is truly the
ultimate in guitar multi-effects devices.
Solo Switch and Dynamic Sense
The COSM amps feature a Solo Switch for each channel, which instantly imparts a feeling of greater power the moment it is
switched on. Additionally, Dynamic Sense provides seamless switching between two COSM amps in response to the nuances
of your picking.
The GT-8 also provides additional features—for example, it allows you to control effects with your guitar's volume knob.
Quick Settings
Each effect incorporates Quick Settings, a function that lets you create the effects you like quickly and easily merely by
selecting preprogrammed settings. Storing your original settings then allows you to create your sound rapidly.
External Loop & Amp Control
The unit includes an external loop feature, which allows you to connect external effects devices. You can freely set the order
in which the GT-8's effects are connected as well as the send and return levels. The GT-8 is also equipped with an amp control
jack, enabling you to use the GT-8 to switch preamp channels on the connected device. Whether you use it for live
performances or recording, you can make the GT-8 the centerpiece of your guitar platform.
Expression/Control Pedal and Internal Pedal System
The unit comes equipped with an expression pedal/switch and control pedal, which allow you to make separate function
settings for each individual patch. Not only can you use the expression pedal as a wah pedal or volume pedal and the control
pedal for holding sounds, the GT-8 also includes an "internal pedal system," which allows you to realize even greater
flexibility in performance.
All the Basic Functions Needed for Professional Use
No compromises are made when it comes to basic functions. The GT-8 comes equipped with dedicated knob controls, which
allow you to make adjustments intuitively and in real time; input level/presence, which enables you to correct the tone of the
connected guitar; a Smooth Patch Change mode, which carries effect sounds over when you switch patches; high-quality 24-
bit A/D-D/A converter; a digital out (using a coaxial connector), which lets you switch between the dry sound, various
effects sound, and the master output; and more.
COSM (Composite Object Sound Modeling)
Composite Object Sound Modeling (COSM) is Roland's innovative and powerful sound modeling technology.
COSM analyzes the many factors that make up the original sound, such as the electrical and physical characteristics of
the original, and then produces a digital model that can reproduce the same sound.
