What is Comp (Compressor)?
Comp, which is an abbreviation for Compressor, is one of the GearBox Effects. Compressors even out
signals by reducing the volume of the loudest sounds to better match the volume of quieter sounds.
You can use subtle compression to make your guitar playing sound more even, or drastic compression
for dramatically increased sustain and a very consistent level. For details on each of the Compressor
controls, move your mouse over the control and look in the Info Bar at the bottom of the GuitarPort
window.
The GearBox Stomp effect also includes the Vetta Comp compressor that runs “pre” (before) the amp
processing, which can give a different kind of sound than the dedicated Comp effect which always runs
“post” (after) the amp processing.
Some effects are modeled after classic gear described in the Model Gallery .

What is Core Audio ® ?
Core Audio ® is a Mac ® protocol for computer audio that allows audio software to communicate
with audio hardware. Most all popular Mac ® audio recording programs now utilize Core Audio to
communicate with a soundcard or other audio device. Line 6 TonePort, GuitarPort, POD X3 and
PODxt devices come with Core Audio drivers - these drivers are installed when you run the GearBox
application installer, or can be downloaded individually from the Line 6 Support - Software Downloads
page.
Core Audio also provides excellent performance on Mac ® systems since it allows the input signal that
is fed into the soundcard travel through the computer, your audio software, and back out the soundcard
outputs in a very short amount of time. This is what is referred to as “low latency” operation. Please see
your Mac ® recording program’s instructions for details on Core Audio operation.
