The Output switch toggles between mono and stereo (Dual) processing. Its influence on the sound varies considerably depending on the amp model used but can add (or subtract) вЂќedgeвЂќ or вЂќcrispness.вЂќ Presence is an additional tone control for mid/high frequencies in the power amp stage. For example, increasing EQ levels can, in some cases, also increase the amount of distortion. As on a real-world amplifier, AmpвЂ™s EQ parameters interact with each other - and with the rest of AmpвЂ™s parameters - in non-linear and sometimes unpredictable ways. The Bass, Middle and Treble knobs are EQ controls that adjust the timbre of the sound. When using the Blues, Heavy and Bass models, high Volume levels can also add considerable distortion. Higher Gain settings result in a more distorted sound.

Although Gain and Volume work together to determine AmpвЂ™s overall level, Gain is the primary control for the distortion amount. Gain adjusts the level of input to the preamplifier, while Volume adjusts the output stage of the power amplifier. This makes it very easy to quickly change the overall character of your sound without having to make numerous adjustments.

Bass is modeled after a rare PA from the вЂ™70s which has become popular with bass players due to its strong low end and вЂќfuzzвЂќ at high volumes.ДЄlthough the real-world versions of these amplifiers all have unique parameters, LiveвЂ™s Amp effect uses the same set of controls for each model.

Heavy is based on the вЂќVintageвЂќ channel of the same amp and is also ideal for metal and grunge sounds.

Lead is based on the вЂќModernвЂќ channel of a high-gain amp popular with metal guitarists.

This is perhaps the best known rock amp of all time.

Rock is modeled after a classic 45 watt amp from the вЂ™60s.

This classic amp is popular with country, rock and blues guitarists.

Blues is based on a вЂ™70s-era guitar amp with a bright character.

Boost is based on the вЂќTremoloвЂќ channel of the same amp, and is great for edgy rock riffs.

This amp was widely used by guitarists of the British Invasion.

Clean is based on the вЂќBrilliantвЂќ channel of a classic amp from the вЂ™60s.

There are seven amp models to choose from: Developed in collaboration with Softube, Amp uses physical modelling technology to provide a range of authentic and usable amplifier tones, with a simple and consistent set of controls. (Note: the Amp effect is not available in the Intro, Lite and Standard Editions.)ДЄmp is an effect that emulates the sound and character of seven classic guitar amplifiers. The Working with Instruments and Effects chapter ( see Chapter 19) explains the basics of using effects in Live.

Live comes with a selection of custom-designed, built-in audio effects.
