Axess Electronics GRX4  Midi Effects Switcher

Sorry, this listing is no longer available.


This is an Axess Electronics GRX4. It allows you to place pedals in each of the 4 separate loops, and then activate them via MIDI in any combination that you choose. These units are getting harder to find, and are still considered to be very desired by pro players for one simple reason - they work incredibly well all of the time.

I bought this unit used (but not abused) several years ago for a backup and literally never even fired it up. It's in great condition. If you have any questions, please feel free to shoot me a message. Thanks.

Specs per Axess Electronics:

The GRX4 Guitar Router/Switcher is a
passive, no noise, sonically transparent guitar
audio router and switcher.

• Relays with gold-plated contacts route the
audio signal with absolutely no tone
coloration or degradation.

• The signal path is configured as a series
chain of three bypass loops (which can also
be used for parallel fx splitting when a plug is
not inserted into the return jacks) and one full
loop which can also be used for "A or B"
switching, parallel FX mute switching or
isolated NO/NC latched or momentary control
function switching of a guitar amp's channels.

• An input (INA) buffer can be activated via an
internal switch to optimize pickup tone and
prevent HI-Z guitar signals from being loaded
down or picking up noise (see the
"Connections" section for more information).

• Capable of switching both instrument level
(pedals) and line level (rack - with the buffer
deactivated) audio signals.

• Can be used with any MIDI footcontroller
capable of sending Control Change or
Program Change messages.

• An infinite number of GRX4's can be used
simultaneously or added to existing rigs with
other switchers.

• Powered by a 9VDC Adapter (like those from
Boss) with a 5.5mm/2.1mm barrel connector.

• Housed in a compact (7.50" x 4.75" x 1.50")
and rugged .064" thick aluminum enclosure
for years of reliable use and performance.

• Brushed finish with black anodize coating and
laser-engraved printing. I WILL NOT SHIP INTERNATIONALLY. USA - lower 48 only. Thank you.
