Each amplifier serves a specific purpose. Modelling amplifiers are designed to mimic the sound of modern and vintage amplification gear, although physically they might look like conventional guitar amplifiers. The settings are different for each one. The modelling amplifier for guitar offers diverse sounds and volumes. Delay and chorus guitar effects are common, and this kind of amplifiers have them integrated within their structure. Modelling amplifiers tend to be effect processors as well as guitar amplifiers.
Microprocessor technology has permitted the employment of digital onboard effects within the diverse guitar amplifiers. Microprocessor technology has led to a huge array of devices commonly known as modelling amplifiers, which can be managed from a computer or laptop through a USB connection. These modelling amplifiers are able to mimic different sounds, such as tube amplifiers, speaker cabinets and all sorts of microphone placements.
There are certain environments where it’s important to manage the volume since high noises should be controlled or even avoided. Because of this, modelling amplifiers let the guitar player connect the output jack of the loudspeaker directly to the main sound system, skipping the on-stage speaker completely. By doing this, the player has a total volume control.
Guitar players have modified their strategies throughout time. Nowadays guitarists tend to use FRFR, a full range, flat response system that has substituted the PA system that was commonly used years back. It all depends on the environment you are performing. The modelling amplifier connects directly to the FRFR system, permitting the adequate setup for a specific tonal colouration for live performances.
Modelling amplifiers have many advantages over tube amplifiers and glass tubes. Modelling amps are quite strong, light and portable, also, they are built on computers and chips. Tube amps and glass tubes are much more fragile and might have to be replaced more often.
