Woodshed Comp Overview
The Andy Wood Woodshed Compressor: The rst pedal designed alongside
one of our Suhr artists. Together, Kevin Suhr and Andy Wood have built a
compressor that is the foundation of some of Andy’s favorite tones. As you
know, Andy plays in multiple musical environments and this small compres-
sor echoes his versatility. Compression is used to even out your signal, as
well as give you more sustain and punch, giving you added control over the
dynamics of your audio signal. Dynamics refers to variation of the volume of a
sound or note, over time. Some instruments have a fast initial sound and de-
cay smoothly, while other instruments have a slower, more violin-like attack.
All can be sculpted with compression� The conception of the Suhr Woodshed
Comp was to make something unique and with more character than the com-
monly used compressors on the market� Compressors are like overdrives;
they all have different avors and do different things. With the Woodshed
Comp, the main goals were to provide compression while maintaining the
tone and transients of the guitar, without being as temperamental as vintage
pedals�
Sometimes, when you start squeezing and compressing, you start losing tran-
sients, but not with the Woodshed Comp. There are spikes and imperfections,
however, these are what make a tone truly great and make guitars sound like
guitars, not like a midi le. Our goal was to retain these nuances while adding
soaring sustain, without having to resort to too much drive and distortion. The
Woodshed Comp is the best way to keep that fundamental tone, especially
when you’re using different amps at different volumes in different venues.
Thank you for purchasing the Suhr Woodshed Compressor
Please take the time to read this User Guide to get the most out of the
Woodshed Compressor. The more you familiarize yourself with the features
of this unit, the more you will enjoy its benets and maximize its potential.

Woodshed Comp Overview (continued)
The Suhr Andy Wood Woodshed Comp is set with a fast-attack speed and
balanced compression that allows the guitar to sing, punch, and have that
sustain. Andy wanted the control’s sweet spot to be in a specic place. In turn,
you get a very sensitive range of the controls with a wide sweep, expanded
ratio, threshold and gain range. This allows the threshold to work on lower
signals, such as single coils. With the Woodshed Comp, a little goes a long
way when dialing in your compression. Woodshed Comp is more natural,
open, and present than anything else you’ve heard. This allows you to get
long, soaring sustain, without the need to push your gain too high on your
amp. This gives you that singing sustain, without the zz.
There are all different types of compressors, VCA, FET, tube compressors,
all with different characteristics. VCA compressors are known for being quick
and having less distortion than FET or tube compressors. Our Koji Comp is
a VCA compressor that’s more similar to more popular compressor pedals
on the market. The new Woodshed Comp is completely different. Though it’s
also a VCA compressor, it uses a completely different process for gain-reduc-
tion. The biggest difference between the Koji Comp and the Woodshed Comp
is how the gain-reduction is controlled. Where the Koji is a ‘feed-back’ design,
the Woodshed is a ‘feed-forward’ design. ‘Feed-forward’ works by the sig-
nal going into the side-chain, which controls the gain-reduction of the whole
thing. In essence, in a ‘feed-back’ design, the output controls the gain-reduc-
tion, and in ‘feed-forward’, the input controls the gain-reduction. The Wood-
shed Comp is a very simple, feed-forward studio-type VCA compressor circuit
that has been tailored to work incredibly with guitar. The ‘feed-forward’ aspect
ultimately makes the Woodshed Comp more transparent and open than any-
thing else you’ve heard.
One of the most exciting features of the Woodshed Comp is that it has a
massive amount of headroom. In fact, the most headroom out of any of our
pedals. In essence, you can use it as a clean boost, with minimal to no com-
pression, and it would act as a high-gain boost.
By boosting the beginning of your signal chain and clipping the front of a tube
amp, you can get a nice saturation and palm-mutes sound just incredible. All
of that in such a tiny and durable package.

Woodshed Comp Controls
This guide will show you how to get the most out of you Woodshed comp
and give you an explanation of each control and how they work together.
Ratio Knob:
Once you have the Threshold hold set, use the Ratio Knob to control how
much level reduction (compression) for any signal that goes above the set
threshold. The counterclockwise position will give a 1 to 1 (1:1) compression
ratio, meaning there is no compression occurring. As you turn the Ratio knob
clockwise the ratio of compression will increase to ∞ to 1 (∞:1). In essence,
turning the Ratio knob clockwise increases the ratio, giving you more
compression, while turning it counterclockwise lowers the ratio, giving you
less compression�
☺☺HELPFUL TIP: If you have the Ratio set counter-clockwise, you will get
no compression when your signal reaches the set threshold. However,
if your threshold is set too high, you will also get no compression of
your signal, regardless of your Ratio Knob setting.
☺☺HELPFUL TIP: The Threshold knob and Ratio knob work together to
set the amount of compression, depending on how hard or soft you
play. If you want compression when playing softer, set the Threshold
low. If you only want your hardest played notes to compress, set the
Threshold Knob higher.
Threshold Knob:
The Threshold Knob sets the level at which the compression starts to take
effect. The higher (clockwise) you adjust this knob, the harder you must play
before compression. The lower (counterclockwise) you set this knob, the
sooner compression starts to occur, even when playing softly.

Woodshed Comp Controls (continued)
Gain Knob:
The Gain knob can be thought of as "output" gain, or "make-up" gain. When
using compression, the signal volume becomes lower initially. This knob al-
lows you to "make-up" that lost level. Adjust this knob to boost a compressed
signal back up to your desired level.
☺☺HELPFUL TIP: Because of the incredibly high headroom (9Vdc pow-
er adapter input gives the circuit 24V due to internal 'charge pump'
circuit), with the Ratio Knob all the way down (1:1), Woodshed Comp
can be used as a boost, allowing you to hit the front of your amp with
additional level�
Attack Speed Switch:
Instead of having a knob to adjust the Attack Speed, Andy wanted to simplify
the choices. "On most compressors I use, the attack speed knob will stay in
one of three positions, Fast, Medium or Slow attack speed. So we made it an
easy switch."
☺☺HELPFUL TIP: A fast (F) attack speed, will allow less transients to
come through before the signal compresses, smoothing out dynamics.
The slower the attack speed, the more pick attack and punch will come
through before compression starts.

Quick Start Guide
Steps:
1. Plug-in 9vdc pedal power adapter.
2. Connect your guitar to the Input of the Woodshed Comp via a 1/4" cable.
3�Connect the Output of the Woodshed Comp to your amplier's input.
4. Start with the Attack switch set to Fast (F)
5�With the Threshold Knob set all the way up (clockwise) and the
Ratio Knob all the way down (counterclockwise), set the Gain knob
around 12 O'clock. This is 'unity' gain. Adjust Gain Knob slightly as you
play and turn on and off the Woodshed Comp, to nd the exact spot
where your volume is the same with the pedal on or off�
6�Set the Ratio Knob to ~10 O'clock
7�As you play, slowly turn the Threshold knob counterclockwise to lower the
Threshold of when compression begins. As you turn the Threshold down,
you will hear the Woodshed Comp compress your signal, lowering the
over-all volume�
8�Then adjust the Gain knob to "make-up" the volume loss and return your
signal to a similar level as when the Woodshed is off.
9�Now, listen to your compressed tone. If you wish to compress your signal
more, turn the Ratio knob (clockwise) to increase the compression ratio or
lower the Threshold knob (counterclockwise) to begin compressing your
signal at quieter playing levels, or both. Always use the Gain knob to bring
your levels back to unity gain.
