Cabinet Match
Like with the Eq and Power amp sections also the Cabinet can be Matched
with the preamp model to automatically get the most appropriate cabinet
type for the chosen preamplifier
(fig. 32)
.
For example selecting the Vintage Clean preamplifier with the Cab Math
active the British 2x12 cabinet will automatically be selected, as this is the
real Vox Cabinet.
By activating both the Amp and Cab Match simply selecting the preamp will
select the entire amplifier in a trice, passing from a Super Reverb to a JCM-
800, for example, with a single knob movement.
Microphone Modeling
A good cabinet must be very well miked to get the right sound in the studio
or onstage.
AmpliTube™ even provides accurate miking that’s not fixed
(fig. 33)
- you
can select some different configurations and placement of the microphone
in front of the speakers. You can select between Dynamic and Condenser
microphone types, in-axis, off-axis, close or far placements.
These differences in the sound have also been sampled from the original
speakers with different miking techniques and the result is a very accurate
emulation by AmpliTube™.
Tremolo
The AmpliTube™ tremolo
(fig. 34)
is the exact recreation of the Opto-
Tremolo that you find inside the 60’s Fender® amps.
The shape of the waveform is typically “vintage” and it’s so particular
because of the strange interaction that occurs between the lamp and the
opto cell within the tremolo circuit. It is placed before the gain stage, so that
the overdrive tones are modulated by the tremolo too, as required for an
accurate recreation of the majority of classic tremolo sounds.
Spring Reverb
There are no digital reverbs that can deliver this tone.
For many years the guitar amplifier’s reverb unit was a double metallic spring
to which the sound was applied at one side and picked up at the other. It’s a very
strange kind of reverb, nothing to do with real rooms or digital devices; it’s a
rough resonant sound that is thought to be unbeatable for certain kinds of,
mostly, clean sounds. AmpliTube™ spring reverb
(fig. 35)
is patched between
the amplifier’s stages, like in the real things and the sound is really close to the
very particular one of the spring, use it specially on clean non sustained sounds.
