Introduction

Got hiss? Get HUSH! The MicroHUSH is Rocktron’s world famous noise reduc­tion in a micro chassis that will take up less space on your pedalboard. The Micro­HUSH will wipe out hiss, unwanted feedback and pickup buzz by providing up to
65dB of signal cleanup, while your music signal integrity remains unaffected. In
other words, get rid of the noise without altering your tone! 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.”

Rocktron’s MicroHUSH pedals are built into a compact yet a rugged chassis,
minimizing the footprint it has on your pedal board. The MicroHUSH is a TRUE
BYPASS pedal: when you turn it off…it is out of your signal path!

Plug the MicroHUSH in AFTER distortion boxes, wahs, noisy vintage effects,
or other noisy units and turn the THRESHOLD control knob until the noise goes
away. It’s that easy! Unlike noise “gates” that chop off the end of your notes, or
ruin your sustain, the MicroHUSH (and other Rocktron HUSH products) are actu­ally a form of single-ended noise reduction that tracks your signal all the way and
pushes the noise floor down below the point where your ear can hear the noise.
The MicroHUSH will not alter your sustain or chop the end of your notes. Simply
use the Threshold knob to smooth out your signal while saying goodbye to noise
forever!

The MicroHUSH does not eliminate 60 cycle ground loop hum. If you are expe­riencing 60 cycle ground loop hum then we recommend the Rocktron Buzz Kill
Audio Isolation transformer (see www.rocktron.com for more information on the
Buzz Kill.)

Here’s more HUSH tips: For maximum noise reduction results, place the Micro­HUSH after your distortion and modulation effects (chorus, flanger, 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 MicroHUSH AFTER
your noisy stomp boxes or in your amp’s effects loop. The MicroHUSH is NOT
designed to take the input directly from your guitar WITHOUT some processing 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 MicroHUSH, you will love how it cleans up the excess noise, including pickup
buzz! The MicroHUSH can also be used in your amplifier’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 MicroHUSH will give you the same great HUSH noise reduction used by thou­sands of high profile artists for years! Add true bypass and the MicroHUSH becomes
a great addition to any pedal board.

The footswitch on the MicroHUSH controls On/Off status as shown by the LED indi­cator. The MicroHUSH requires a 9V DC power source (not included). We recom­mend the Rocktron DC OnTap Universal Power Supply adaptor. More information
on these power supplies can be found at the end of this manual or on our website at:
