3 - Controlling AmpliTube™ LE
21
Amp section
The amp section of AmpliTube™ LE (fig. 19) provides everything needed to
precisely craft a huge amp sound ranging from clean to lead.
The AMP MODEL switch allows to select among three different kind of Amp
models:
- Clean Modeled after the Vox® AC-30 top boost
This is modeled after a Top Boost version of the Vox® AC-30 preamplifier. It
has the best presence and definition in the mids and highs. It is very sensi-
tive to the tone of the guitar and perfect for all pop/rock electric accompa-
niments and can be easily driven with the Overdrive Stomp to produce crun-
chy and creamy tones.
- Crunch Modeled after the Marshall® JCM-800
This is modeled after a Marshall® JCM800 super lead. This is a single chan-
nel head, where the GAIN control has a dramatic range of control over the
sounds - and we provide exactly the same control here. It is bright and “lite”
at very low gain settings, with only a little crunch when the input signal is
increased; but when increasing the gain knob the sound becomes more dri-
ven AND fatter, up to a quite high gain- useful for lead too but always warm.
The higher the gain the warmer is the sound. Astonishingly similar to the
real thing! Also useful at low gains for arpeggios in pop music, for slightly
crunchy but light rhythms while at high gain it becomes the most typical
British crunch/lead sound.
- Lead Modeled after Fender® Solid State combos
This can’t be clean! A lot of gain is provided to deliver all those typical
American extra high gain timbres. It’s very good for really high gain leads
because it is so precise and stable. Furthermore its extra power at the low
end makes it very good for all hard rock sounds. It can also be usefully
played at low gain settings.
The CABINET MODEL (fig. 20) is activated when the speaker switch is set to
ON (and the red LED lights). A guitar amplifier can sound authentic only
with its appropriate speaker system. The frequency response of guitar
speaker systems is very specific and is far from being flat, because guitar
amplifiers use typically full range large single way speakers that cannot
exhibit flat frequency response.
AmpliTube™ LE uses a very high resolution system to capture and reprodu-
ce the tone of a guitar speaker system, for example the frequency response
of all the AmpliTube™ LE cabinets are sampled at very high frequency, this
delivers an ultra-accurate reproduction of all the small but so important
irregularities in the frequency response, even at the high end.
