GT-PRO

For Stage or Studio, the GT-PRO is Built to Satisfy the Most Demanding Professional

■ Computer-Friendly Design

For one-cable patch management and advanced sound design,

a USB port is provided for connecting the GT-PRO to a

computer of your choice; the GT-PRO comes with Mac/PC

editor/librarian software at no additional cost. In addition, it

provides USB-Audio functionality.

■ Powerful Dual COSM Amps

The GT-PRO’s dual COSM amp modeling engine allows

unprecedented tone exploration 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.

■ Meticulous COSM Editing

The GT-PRO crushes the competition with its unique and

powerful COSM editing. Thanks to BOSS’s advanced physical

modeling, you take complete control over your tone by

constructing your virtual rig from scratch, including the choice

of speaker types, microphone amp position, and more.

■ Solo Switch

The 46 COSM amp models built into the GT-PRO contain 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

Looking for BOSS’s best effects? You’ll find them here. As the

top of GT line, the GT-PRO provides 44 effects categories, with

200 preset- and 200 user-patch locations. Choose from

compressors, overdrives, delays, reverbs, choruses, EQs,

wahs, and dozens of other BOSS-quality effects — including a

sitar and acoustic guitar emulator onboard.

■ Flexible Effects Chain

Prepare to be impressed with the GT-PRO’s flexible effects

chain. Internally, the 15 effects blocks can be

configured in any order you desire; externally,

a trio of stereo effects loops plus an array of

assignable outputs enables the most flexible

signal-routing configurations.

■ 2-Channel External Amp Control

The GT-PRO provides two Amp Control jacks,

which can be programmed independently to

switch amp channels, operate external

effects, and more.

■ 2-Channel individual Stereo Outs

I/O flexibility is the name of the game with the GT-PRO, as it

also provides four 1/4-inch analog audio outputs, a pair of

balanced XLR outputs, and three pairs of effects send/returns.

If you wish to add some serious settings for the stage

environments, you can split the signals independently to a

couple of guitar amps and go to the PA with the stereo Sub

Outs at the same time.

■ Connecting With Power Amps, Plus Cabinets ■ Using the GT-PRO’s Effects Loops

Connect to the JC-120. Using

JC’s stereo return jacks, you

can take advantage of the GT’s

stereo effects.

■ Connecting With Guitar Amps

Using two individual outputs,

you can select guitar amps

with the patches you’ve

programmed.

In the same way, you can

freely control stereo sounds

with four guitar amps.

Record to DAW software

through the GT’s USB port. The

same sounds can be monitored

through your guitar amp.

■ For Recording

Connect the stereo outputs to

a single power amp for Dual

mode or stereo effects.

Connect each output channel to

individual power amps and

cabinets. You can designate the

output channel per Patch.

Connect the Sub outs to a

stage PA. Another channel is

used for monitoring.

Pre loop is used for a branch

out. Removing the direct sound

from the Master outputs, you

can divide dry and wet sound.

The GT-PRO is useful for post-

production. After recording,

you can reamp your dry guitar

sound with a single USB

connection.

Up to three external effects can

be used. You can assign effects

loops ON/OFF per Patch.

Connect a guitar amp’s

send/return to the GT’s Pre

loop. You can select each

preamp case by case.

Using GT’s digital output, you

can immediately record your

live performance with pristine

quality.
