2 - Using AmpliTube™ LE

Amp Section

After passing through the stomp box section the signal goes into the heart

of AmpliTube™ LE: the Amplifier emulation (fig. 4).

Here everything is physically modeled and the signal first

feeds into the gain stage with 3 Amp Models to choose

from:

Clean Modeled after the Vox® AC-30 top boost

Crunch Modeled after the Marshall® JCM-800

Lead Modeled after Fender® Solid State combos

The AmpliTube™ LE amps are directly taken from some of

the best preamps ever made, and the tonal spectrum cove-

red by all the AmpliTube™ LE preamps is exceptionally

wide.

In the amp the signal feeds into the EQ stage (fig. 5), a “tone control” circuit

that recreates the authentic response of the tone shaping section of the best

amplifiers. Actually this is not a conventional digital EQ. It sound exactly

like the typical “bass”, “mid” and “treble” knobs you would expect to find on

the amplifier faceplate, and, best of all, its “sound” and character changes

according to the Preamp type that’s been selected.

Just after the EQ stage we find the Spring Reverb (fig. 6). This reverb really

sounds very close to a spring unit, with all the warmth they have together

with that typically metallic and resonant vibe.

After being amplified, the signal is fed to the Cabinet Models (fig. 7). Here

is where AmpliTube™ LE recreates, thanks to meticulous measurements

with unprecedented precision, the magical tones of some of the best guitar

speaker system ever made. The speaker frequency response is the most

important stage of the guitar system because every subtle nuance of the

cabinet frequency response is responsible for a particular tonal character,

and the AmpliTube™ LE cabinet emulation is very precise.

3 Cabinet Models are offered into AmpliTube™ LE:

Open back 1x12” Modeled after Ampeg® AX-30 100W Tube Combo - 90’s

British 2x12” Modeled after Vox® top boost AC-30 - 60’s

Vintage Closed 4x12” Modeled after Marshall® vintage 4x12 cab – 70’s

For more versatility, the cabinet emulation can be switched off in order to

obtain an amp direct-out signal.
