Introduction
Got hiss? Get HUSH!
Rocktron provides a new twist on the world famous HUSH
guitar noise reduction with the HUSH 2X. Essentially a
“double HUSH”, the 2X offers two completely separate
channels of HUSH noise reduction in a single small unit
designed to sit right on top of your guitar amp/head or in
a rack drawer, freeing up space on your pedal board. The
HUSH 2X is also TRUE BYPASS.
This unique design allows you to choose if you want to run
HUSH after your pedal board and into the input of your
head with one circuit, and into the effects loop with the
other circuit offering new versatility in a single HUSH unit.
You get total HUSH control both in front, and in the effects
loop, of your amp! The HUSH 2X will also allow you to
use one HUSH circuit before, and another after, a single
pedal or with two different pedal chains on your pedal
board/rack drawer. Selector switches allow you to turn
each HUSH circuit on or off.
The same great HUSH signal cleanup is provided with up to
65dB of effective noise reduction for eliminating hiss, un-
wanted feedback and noise from pickups and stage lighting.
Guitar Player Magazine wrote that a “HUSH” pedal will
work for all guitar-related noise problems: it’s perfect” and
“its potent noise-killing abilities will be fully appreciated.”

For maximum noise reduction results, place the HUSH after
your distortion and modulation effects (chorus, anger,
phaser, etc.) but before any delay or reverb effects. If you
are already comfortable rolling back your guitar’s volume
pot, simply turn your distortion and other effects in the
chain before the HUSH to “ON”, roll back your volume
pot, adjust the HUSH Threshold control to remove any hiss
you hear, and you are ready to go!
Make sure you pay attention to the proper setup by placing
the HUSH AFTER your noisy stomp boxes or in your
amp’s effects loop. The HUSH is NOT designed to take the
input directly from your guitar WITHOUT some process-
ing happening between the guitar and the noise reduction.
When setup correctly, with your signal going from your
preamp and effects, or from your distortion and effects, into
the HUSH, you will love how it cleans up the excess noise,
including pickup buzz! The HUSH can also be used in
your amplier’s effects loop. However, if you are running
multiple effects through this loop, the HUSH should always
be the last dynamic device in the signal chain, but before
digital delays or reverbs.
The HUSH will give you the same great HUSH noise
reduction used by thousands of high prole artists for years!
The switches on the HUSH 2X controls On/Off status of
each channel as shown by the LED indicator. The HUSH
2X runs on a 9V Alkaline battery, or may also be powered
by Rocktron’s DC OnTap Universal Power Supply adaptor.

CHANNEL 1 - THRESHOLD Control determines
the minimum input level at which the HUSH lter
and downward expander will begin to operate.
Setting this control too high will result in a loss of
sustain, as notes will tend to die out much faster
than they should. Conversely, when set too low, the
expander will close too late (if at all) and the noise
oor will remain audible
CHANNEL 1 - SWITCH - This switch allows for the
HUSH to be bypassed when noise reduction is not
required.
CHANNEL 1 - ON/OFF Led - When lit, the LED
indicates that the HUSH is currently active in the
signal path.
CHANNEL 1 - INPUT Jack - Using a standard 1/4”
guitar cable, plug into this jack AFTER any noisy
pedal/effect or from an “effects send”.
CHANNEL 1 - OUTPUT Jack - Using a standard
1/4” guitar cable you can plug in another pedal from
this jack or plug directly into your amplier or to the
“effects return.”
