340 Live Audio Effect Reference
Boost is based on the ”Tremolo” channel of the same amp, and is great for edgy rock riffs.
Blues is based on a ’70s-era guitar amp with a bright character. This classic amp is popu-
lar with country, rock and blues guitarists.
Rock is modeled after a classic 45 watt amp from the ’60s. This is perhaps the best known
rock amp of all time.
Lead is based on the ”Modern” channel of a high-gain amp popular with metal guitarists.
Heavy is based on the ”Vintage” channel of the same amp and is also ideal for metal and
grunge sounds.
Bass is modeled after a rare PA from the ’70s which has become popular with bass players
due to its strong low end and ”fuzz” at high volumes.
Although the real-world versions of these amplifiers all have unique parameters, Live’s Amp ef-
fect uses the same set of controls for each model. This makes it very easy to quickly change the
overall character of your sound without having to make numerous adjustments.
Gain adjusts the level of input to the preamplifier, while Volume adjusts the output stage of the
power amplifier. Although Gain and Volume work together to determine Amps overall level,
Gain is the primary control for the distortion amount. Higher Gain settings result in a more dis-
torted sound. When using the Blues, Heavy and Bass models, high Volume levels can also add
considerable distortion.
The Bass, Middle and Treble knobs are EQ controls that adjust the timbre of the sound. As on a
real-world amplifier, Amp’s EQ parameters interact with each other — and with the rest of Amp’s
parameters — in non-linear and sometimes unpredictable ways. For example, increasing EQ
levels can, in some cases, also increase the amount of distortion.
Presence is an additional tone control for mid/high frequencies in the power amp stage. Its
influence on the sound varies considerably depending on the amp model used but can add (or
subtract)edge” or ”crispness.
The Output switch toggles between mono and stereo (Dual) processing. Note that in Dual mode,
Amp uses twice as much CPU.
The Dry/Wet control adjusts the balance between the processed and dry signals.
