Acoustic Simulator
The AxSys provides two different Acoustic Simulator Preamp types.
These simulate the sound of an acoustic guitar with a pickup or a piezo
transducer in the saddle.
TIP For the best simulation, always select the pickup closest to the
guitarÕs neck. Single coil pickups tend to sound better because of
their bright tone; and a bright, stringy sound is the signature of an
acoustic guitar. If you are using a humbucking pickup, try using a
coil splitter to disable some of the coils and brighten the sound up.
When either of the Acoustic Sim Preamp types are selected, the following
parameters will be disabled:
Noise Gate On/Off Noise Gate Threshold Noise Gate Decay
Preamp Bass Preamp Middle Preamp Treble
Bright Switch Preamp Output Level Distortion Box
Distortion Box On/Off Rando-Wah Sample/Hold Wah
Drive Drive On/Off
Bright Switch
The BRIGHT SWITCH parameter is your basic brightness booster.
The BRIGHT SWITCH control is disabled when the Acoustic Sim Preamp type is
selected. If you attempt to modify it, the display will temporarily read

.
Presence
The PRESENCE parameter provides a boost of the high-mid frequencies,
and raises the signal level a bit. It can be adjusted between 00 and 99.

5-Band Graphic EQ
A graphic EQ is a set of bandpass filters used for general tonal shaping, as
in many home stereos. The 5 bands in the Graphic EQ of the AxSys 212 are
about an octave and a fifth apart at 80Hz, 240Hz, 750Hz, 2200Hz and 6600Hz.
Each of these may be set between -19 and +19 dB, providing a cut or boost,
of their respective frequency range.
Parameter Range Description
80Hz -19 to 19 Cuts or boosts the frequency range centered at 80Hz.
240Hz -19 to 19 Cuts or boosts the frequency range centered at 240Hz.
750Hz -19 to 19 Cuts or boosts the frequency range centered at 750Hz.
2200Hz -19 to 19 Cuts or boosts the frequency range centered at 2200Hz.
6600Hz -19 to 19 Cuts or boosts the frequency range centered at 6600Hz.
