COMPRESSOR

USER’S GUIDE

Congratulations on your purchase of the Studio Bass Compressor Pedal.

The Studio Bass is a studio-grade, classic compressor in a user friendly 4 knob format.
Our unique Blend knob and 3 way mini-toggle switch allow you to select the frequency
range of the original uncompressed signal as well as infinitely adjust the amount of “wet”
versus “dry” signal that is routed to the output.

It’s often best to put a compressor at the beginning of your effects chain, but sometimes
it can work more efficiently when placed after effects such as an auto wah or envelope filter.
You won’t do any damage by putting your effects in the so-called wrong order, so feel
free to experiment and find what works best for your sound.

Typical applications for the Studio Bass include:

• Accentuate picking and single note runs

• Increase sustain

• Even out all of the notes

HOW IT WORKS

1

Blend – Determines how much of the original

signal is blended back into the compressed
signal. This control allows you to play above
the compression threshold to bring the natural
snap back to individual notes or a passage
when you really dig in.

2

Low/Full/Mid Switch – This switch works in

concert with the Blend knob. It determines
the frequency content of the dry signal being
blended in with the compressed signal. Using
the Frequency switch and the Blend control,
you can restore some of the dynamic range lost
in compression and choose to be frequency
selective or dial it in full range.

• In the “Low” position, frequencies below 200
Hz are given more emphasis in the dry blend.

• In the “Full” position, all frequencies are given
equal weight in the dry blend.

• In the “Mid” position, frequencies in the range
from 150 Hz to 1.5 kHz are given more emphasis
in the dry blend.

Compression – This knob is the heart and

soul of the Seymour Duncan Compressor
as it determines the amount to which you
will limit the dynamic range. You will need
to carefully balance your Compression and
Attack settings. If you turn the Compression
to maximum, you will want to keep the
Attack control at or near minimum to avoid
pumping, breathing or other unnatural
artifacts. To some degree, you can offset
these effects by using the Blend control
to bring uncompressed signal back into
the mix.

4

Attack – This crucial control regulates how

quickly the compressor reacts to your initial
pick attack with the circuit acting to compress
the input signal. For increased dynamics,
a higher setting will give a late attack that
allows your pick or finger dynamics to come
through before the compression kicks in.

5

Volume – Always important, this knob can

be used to achieve the desired level balance
between the sound though the compressor
and the bypassed sound. Balance this with
the sustain knob to provide as natural an

effect as possible. Alternatively, to use the
Studio Bass as a clean boost, set the output
to a higher setting and lower the amount
of compression.

6

Status LED – Indicates when the Studio

Bass Compressor is active. LED is on when
the unit is engaged, off when in true by
pass mode.

7

True Bypass Footswitch – Removes the

circuit from your bass' signal via a hardwired
connection from the input jack to the output jack.

Input Jack – Plug in your bass or other

pedal cable here.

Output Jack – Run a cable to the input of

your amp or to the next effect in your chain.

10

Power Jack – We designed this pedal to be

convenient. You can use any 9V to 18Vdc
regulated adapter (negative polarity center
terminal).

Easy Access Battery Door – When pedal is

not in use, save your battery life by removing
your cable from the input jack.
