POWER AMP & GUITAR SPEAKERS
Global Settings: Modified (see below)
Presets: Factory or Custom
This popular setup uses a power amp and traditional guitar speakers, which are NOT full-range or flat response,
so speaker simulation is disabled globally. Blocks are used to recreate stompboxes, amps, and studio effects.
Depending on your amp, power amp modeling may also need to be disabled globally.

IMPORTANT: For this setup, bypass Cabinet Modeling
under Global Settings.
Navigate to SETUP: Global Settings: Config.
Change Cabinet Modeling to “BYPASSED”.
CONSIDER YOUR POWER AMP...
There are two categories of power amp that you can
use with the Axe-Fx III. A sonically “neutral” power amp
is generally the preferred variety. Such amps (mostly
solid-state) allow you to use Power Amp Modeling in the
Axe-Fx III, which accurately recreates the appropriate
power amp tone and dynamics for your selected amp
model.
The second category is “non-neutral” power amps,
typically tube-powered, and made specifically for
traditional guitar rigs. This includes not only rackmount
amps, but the power amp in a tube head or combo—
usable for a rig like this one when you plug directly in to
the amp’s FX RETURN jack. The non-neutral power amp
can sound great, but you’ll be “stuck” with the tone and
dynamics of that particular amp, and you will almost
certainly want to disable Power Amp Modeling as
detailed below:
DISABLE POWER AMP MODELING
IMPORTANT: when using a non-neutral power amp, set
Power Amp Modeling under Global Settings to OFF.
Navigate to SETUP: Global Settings: Config.
Change Power Amp Modeling to “OFF”.
CONNECTIONS
Connect your guitar to Input 1 Instrument.
Connect Output 1 L to the input
of your power amp, which is assumed to
already be connected to a guitar speaker
cabinet. You can also connect to the FX
Return jack on many amp heads/combos.
When using 1/4" outputs, Humbuster cables are
recommended to reduce hum from ground loops.
