Precautions

Introduction
So you have favorite stomp boxes that you just love and adore but you wish
they were TRUE BYPASS pedals. Admit it. Everyone does. Well let Rocktron
put a smile on your face with the Tru-Loop, our incredible new product that lets
you add True Bypass to any non-true bypass effect! You read that right. Your
wish has come true with the Tru-Loop.
The original tone of the source input (such as that favorite pedal of yours)
is unchanged! One more time: the original tone of the source input remains
unchanged while using the Tru-Loop.
The Rocktron Tru-Loop provides Serial or Parallel effects mixing. The “Re-
turn” can merge stereo effect output (RTS) to mono. The Tru-Loop can be used
as a buffered A-B box as well. It can also be used as a 3 channel signal mixer.
D TUNING MADNESS ALERT:
Add an exciting new dimension to your sound using any distortion pedal and
the Tru-Loop’s capability to PARALLEL mix between Heavy Distortion and
your guitar’s original clean sound! The Tru-Loop is great for 7 string or Metal
D tuning to add a sense of focus and articulation to the fastest licks.
Part of the Rocktron Boutique Series of stomp boxes this pedal design comes
in a rugged metal chassis with eye popping retro custom design laser etched
artwork.
Controls on the Tru-Loop include MIX which allows the mix between the
original audio input signal and the effect return. Full counter clockwise equals
series effect. At 12 o’clock setting, you have 50% of the effect plus the original
audio.
INPUT is for the original audio source. SEND is the original audio source to
be used by the effect input. RETURN is the output of the effect.
The footswitch on the Tru-Loop controls On/Off status (indicated by the LED).
This stomp box runs on a 9V Alkaline battery. You may also use the Rocktron
DC OnTap Universal Power Adaptor.

audio input signal and effects in the loop. When the knob is set at 12
o’clock, you have 50% of the origional audio signal and 50% off the
effect. When turned fully to the left you have only the original signal.

in the loop.
