Section 4 - Algorithms
GUITAR AMP 1, GUITAR AMP 2
These algorithms recreate the
warm
sound
of a guitar amplifier. They
do
this
by
emulating
tube
distortion characteristics. These algorithms are
good
for all stringed instruments. Guitar
Amp
1
offers
more
distortion than Guitar
Amp
2.
00 -
Guitar
Amp
1 is designed for
Hard
Rock sounds.
00 -
Guitar
Amp
2 is optimized for "bluesy" type
sounds
.
The
parameters
available for this algorithm are:
01-Mix
02-Volume
See the descriptions
under
the
Mix
and
Volume Parameters,
in
the beginning of this section.
03 - Amp Preamp Gain Range: -48 to +48
dB
This
parameter
adjusts the
amount
of boost
or
cut
applied to the incoming signal. We
recommend
a setting of 00 dB, since these emulations were optimized for distortion there.
Lower
preamp
gains will result
in
less distortion, while higher
preamp
gains will yield clipping
distortion. For
low
preamp
gain, it
may
be
desireable to use low tube bias values.
04 - Output Level Range: 00 to
99
This
parameter
controls the
output
level of the
main
amp
before the
output
EQ.
05
- Amp Tube Bias Range: 00 to
99
For
preamp
gains approximately 00 dB, this
parameter
controls the emphasis of even to
odd
harmonics
which
determines the tone of the amp;
mid
values emphasize even harmonics
and
offer a
warmer
("
glowing
tube")
sound,
while the highest values
may
sound
like tubes going
bad
.
Tube bias
and
preamp
gain are
independent
parameters. For low
preamp
gain, it
may
be
desire able to
use
low
tube bias values, because this more closely imitates the operation of a real
amplifier.
06 - Pre-EQ Input
Level
Trim
Range: -24 to +00
dB
Controls
the
input
level to the pre-amp EQ to eliminate the possibility of clipping boosted signals.
07 - Pre-EQ High Pass Cutoff
Range: 4 to 1000
Hz
This
parameter
filters
out
the low frequencies before the preamp. The higher the value, the less
low
frequencies
pass
through.
08 - Pre-EQ Fe
Range: 100 to 9999
Hz
This
parameter
determines the center frequency of the parametric filter before the preamp.
Higher
values
have
a brighter sound.
09 - Pre-EQ Gain
Range: -48 to +24 dB
Adjusts
the
amount
of boost or cut
applied
to
the
parametric filter in front of the preamp.
10-
Pre-EQ Q
Range:
01
to 18
This
parameter
determines the
width
of the resonant
peak
at
the parametric filter center
frequency. While
the
Filter center
parameter
determines where (at
what
frequency) this
peak
will
occur,
the
Q setting controls the presence of the peak.
