When the GAIN knob is at maximum, this produces a sound with the
lustrous distortion obtained from a vacuum-tube amplifier with the
volume turned all the way up.
You can obtain a near-clean sound with little distortion and unchanged
airy brightness simply by slightly turning down the volume on the
guitar.
By adjusting the volume knob on the guitar together with the GAIN
knob setting, adjusting the GAIN knob so that the amount of distortion
changes naturally depending on your picking dynamics with little
change in volume, you can obtain sound with a broad range of
expressiveness.
This is a blues sound found in vintage amps, with a tenacious midrange
and low end and a bright, open high band.
The boosted midrange and high end are distinguishing characteristics
of the TWEED amp. By turning up the TREBLE knob or lowering the
BASS knob slightly, you can adjust the attack sound of the picking.
To create a fat, sweet sound, reducing the presence a little may be
beneficial.
Conversely, to produce a transparent and sharp crunch sound with
little distortion, lower the midrange while boosting the presence
slightly.
This is a 1970s-style hard-rock sound.
Turning up the gain and the equalizer all the way produces a powerful
rock sound in all riffs and solos.
Applying a clean delay with a short delay time of 30 ms produces a fat
sound characteristic of the sounds emitted by the surfaces of the
cabinet.
Adding just a touch of phaser can also make the sound even broader.
Using effects devices like overdrive as well can produce distortion with
even richer harmonics.
You can also obtain a clear and airy crunch sound by turning down the
GAIN and BASS knobs.
This is a high-gain lead sound with sustain.
If you're using a guitar with single-coil pickups, boost the gain to
produce sustain.
Raise the high end and presence to produce fully developed picking
harmonics. To produce smooth legato notes when using tapping, turn
down the midrange.
To make the sound even fuller, add just a light amount of delay and
reverb. Set a long delay time to keep phrases from becoming muddy.
Applying FLANGER produces a sound with smooth breadth, even when
playing riffs.
