8 BLOCKS GUIDE
Speaker Compression
– Even if you never touch most advanced parameters in the Amp block, don’t overlook
Speaker Compression, aka the “chunka chunka” parameter. It models the interaction of the power amp with
the power compression of a virtual speaker. Typical guitar speakers compress between 3 and 6 dB depending
upon construction, age, volume, etc. The default value is conservative and yields about 3 dB of compression.
Master, Presence, and Depth will interact considerably with Speaker Compression, with higher causing more
compression. A gain reduction meter shows the amount of Speaker Compression when this parameter row is
selected. Note that this parameter does not reset to its default value when changing the Amp Type. Tip: Speaker
Compression is a simulation of what happens in a real guitar speaker, so set it to zero when using a tube power
amp and conventional guitar cab.
Transformer LF, Transformer HF
– These set the output transformer bandwidth.
Transformer Drive
– This models core saturation in the virtual output transformer. Higher values simulate a
smaller, more easily saturated transformer. The distortion produced by an overdriven output transformer isn’t
particularly pretty but it does play a role in the tone and without it the distortion would not be authentic.

INPUT EQ PAGE
The Input EQ parameters adjust a powerful set of filters at the input of the amp block, so its effect is heard before
preamp distortion or a front-end tone stack.
Type, Frequency, Q, Gain
– These parameters work together to define a powerful multi-mode filter that can be
used for anything from a subtle bump to an extreme spike, or from gentle to extreme shelving.
Low Cut
– Adjusts the cutoff frequency of a high-pass filter. This control removes bass frequencies and can be
useful to tighten an amp’s low end, removing “flub”.
High Cut
– Adjusts the cutoff frequency of a low-pass filter. This filter is actually placed between the preamp and
the power amp, so it has a more dramatic effect than an EQ that might be placed before preamp distortion.
Definition
– This control is a basic “tilt EQ” which adds highs/cuts lows, or vice versa.

OUTPUT EQ PAGE
The amp block includes a built-in graphic EQ, eliminating the need to use a separate block for tone-shaping. You
can achieve different results by changing EQ Location in the Advanced menu. To reset the EQ to flat, tap
ENTER
.
To operate the EQ bands, use the
NAV
keys, and
VALUE
or
A,B,C
,
D
and
E
.
To change the number of bands, use the
NAV UP/DOWN
buttons.
EQ Types (Advanced page) include: 3-Band Console, 3-Band Passive, 4-Band Passive, 5-Band Passive, 5-Band
Constant Q, 7-Band Constant Q, and 8-Band Constant Q, 5-Band “Mark”, 7-Band Variable Q, and 8-Band Variable Q.
