Amount parameter
Use the Amount parameter to control how much BodyRez processing should be
applied to your guitar signal.
Amount settings lower than 10 will limit the range of any EQ, Compression
or Ambience settings you can adjust when in BodyRez Advanced mode.
See "BodyRez Shelf EQ page (4/7)" for instructions on how to reveal the
Advanced page.
Low Gain parameter
Use the Low Gain parameter to control the "bass" range of frequencies within the
BodyRez style.
Hi Gain parameter
Use the Hi Gain parameter to control the "treble" range of frequencies within the
BodyRez style.
BodyRez Shelf EQ page (4/7)
This page is hidden by default. To access it, enter the Setup menu and change the
"BodyRez Editing" parameter from "Basic" to "Advanced".
The BodyRez Shelf EQ page provides a highshelf and a low-shelf equalizer with
adjustable Frequency and Gain parameters.
BodyRez Parametric EQ page (5/7)
This page is hidden by default. To access it, enter the Setup menu and change the
"BodyRez Editing" parameter from "Basic" to "Advanced".
The BodyRez Parametric EQ page provides a two-band parametric EQ with
controls for Frequency ("Freq"), Bandwidth ("Width") and Gain.
BodyRez Compressor page (6/7)
This page is hidden by default. To access it, enter the Setup menu and change the
"BodyRez Editing" parameter from "Basic" to "Advanced".
Use the Compressor effect block to control the dynamic range of your guitar
signal, enhancing attack, sustain or both.
Threshold parameter
Use the Threshold parameter to define the signal level at the guitar input where
the Compressor should kick in. The lower the Threshold (-30 dB is lower than
-20 dB), the sooner the Compressor will engage.
Attack parameter
Use the Attack parameter to define how fast the signal's level should be reduced
(as defined by the Ratio parameter) once the signal at the guitar input exceeds
the Threshold value.
Makeup Gain parameter
Depending on the settings of the other Compressor parameters, you may need
to "make up" reduced gain to maintain your output signal level. Makeup gain
allows you keep your signal levels consistent from the input of the Compressor to
the output.
Ratio parameter
Use the Ratio parameter to define the amount of compression applied to the
signal. The signal at the input of the compressor has to exceed the threshold by
the number of decibels (dB) set with this parameter to raise the signal at the
output by 1 dB. Here is an example:
• • Set the Threshold parameter to -10 dB.
• • Set Ratio to 4.0.
• • Now if the level of the signal at the Compressor's input suddenly jumps to
-6 dB, it is 4 dB above the Threshold (-10 dB), and the compressor kicks in.
The Compressor will compress those 4 extra decibels to 1 dB – this is the
compression ratio. Accordingly, the level of the signal at the compressor's
output will only jump from -10 dB to -9 dB.
Release parameter
Use the Release parameter to define how fast the original signal level should be
restored once the signal at the guitar input falls under the Threshold value.
Ambience parameter
The Ambience section of the BodyRez effect block utilizes timing variances to
emulate body resonance from your acoustic guitar. Use the Amount parameter to
set the amount of Ambience applied to the signal.
Guitar Anti-Feedback page (7/7)
In live environments, the open body style of acoustic guitars is especially prone
to feedback from nearby sound sources such as stage monitors or PA speakers.
To assist you with feedback management, there are some controls to address the
most common feedback culprits.
Phase Invert parameter
Use the Phase Invert parameter to invert the phase of the guitar signal by 180°.
This can help prevent feedback when playing your acoustic guitar close to a stage
monitor or other speaker. When you experience feedback, this should be the first
setting to try.
Low Cut Filter parameter
Acoustic guitars can be prone to resonance, especially in the low frequency range.
If you are having trouble with "rumbling" or low frequency feedback, use the Low
Cut Filter parameter to roll off low end frequency from your guitar signal.
Notch Filter section
This very narrow band equalizer can help "hone in" on feedback-causing
frequencies and reduce their gain.
Notch Gain parameter
Use the Gain parameter to set the gain for the note/frequency range you have
selected with the Freq parameter. Use negative values (e.g. -8) to reduce
troublesome frequencies.
If you are unsure which frequency is causing the feedback, it can be useful to use
positive values (8 for example) to boost the feedback you are hearing. This allows
you to highlight problematic frequency ranges more easily. Then, you can reduce
the Gain setting for this frequency range using a negative value.

Notch Freq parameter
Use the Freq parameter to set the frequency of the notch filter. For this
parameter, we show both the frequency in Hz and the relative note (A# for
example). The frequency parameter can be adjusted in 25 Cent increments from
note to note.
Often, you can determine the note that's feeding back by simply playing a chord
and "feeling" which string vibrates unusually under your finger. After you have
selected that particular string/note using the Freq parameter, you can use the
Gain parameter to reduce feedback for that note.
Simple steps for feedback reduction
• • Set the Phase Invert parameter to "On". If this doesn't eliminate the
feedback, try the following steps.
• • Change the Gain parameter to a high positive setting such as 8 or more.
• • Use the Freq parameter to "sweep" through frequencies until the feedback
gets "a lot worse" as you move past it with the Freq control.
• • Once you have found the troublesome frequency, change the Gain parameter
to a negative setting until the feedback disappears.
• • Lastly, if you still get feedback, turn your guitar level down in the Mix section
described next.
8. Mix button/section
Press the MIX button to enter the Mix menu, where various audio signal levels
within your Play Acoustic can be adjusted.

Harmony parameter
Use the Harmony parameter to control the overall level of all voice-generating
effect blocks like Harmony and Double.
Guitar Level parameter
Use the Guitar Level parameter to adjust the output level of the guitar signal.
This control is also dependent on the Guitar input level, set in the Setup menu.
Make sure to set your input level according to the instructions and use the
Guitar Level parameter to set your "overall guitar output volume".
Out Level parameter
Use the Out Level parameter to control the overall output level of your Play Acoustic.
Delay/Reverb level parameter
Use the Delay/Reverb level parameter to change the level of Delay/Reverb effects
across all presets. This control is useful if you find yourself in a performance
environment that has a lot (or very little) natural reverb and you'd like to "tune"
your sound to that room without having to manually adjust all presets.
Headphone Level parameter
Use the Headphone Level parameter to adjust the volume of the
headphone output.
RoomSense parameter
Use the RoomSense parameter to control the amount of ambient RoomSense
sent to the headphone mix. This parameter does NOT enable RoomSense to be
sent to the main mix, as this would cause feedback.
Aux Level parameter
The Aux Level parameter will only be shown if a signal source is connected to the
Aux connector.
Use the Aux Level parameter to adjust the level of the signal received at the Aux input.
If you prefer to only hear the Aux input over your headphones, go to the Setup/
Output menu and change "Aux to Main Out" to OFF.
If you would like the Aux input to "listen" for chord information but not be heard
at via the Main Out or Headphone outputs, set the Aux Level parameter to OFF.
Mix page (2/2)
USB In Level parameter
Use the USB In Level parameter to adjust the level of the incoming USB audio
signal (such as backing tracks).
This control has no effect if Input is set to USB and you are post-processing the
received signal via a DAW. The track controls within the DAW itself will determine
the output level (and therefore the Play Acoustic USB input level).
USB Out Level parameter
Use the USB Out Level parameter to control the level of the audio signal sent
over USB.
If the device you are connected to is clipping at its input, try turning this
parameter down.
