Digital amplifiers, usually referred to as modelling amplifiers, are a relatively new technology that has gained popularity recently. These amplifiers simulate the sound of numerous different amplifiers, effects pedals, and speaker cabinets using digital signal processing.
The audio signal is first transformed into a digital signal before being played through a modelling amp so that the amplifier’s internal processor may change it. The signal is then subjected to a number of algorithms and effects by the processor to produce a unique sound that is catered to your preferences.
The adaptability of modelling amps is one of their benefits. You can simulate the sound of a wide range of various amps and effects pedals with a single amplifier, which can be a reasonably priced approach to experiment with various sounds without having to buy multiple pieces of equipment.
The all-in-one amplifier is a particular kind of modelling amplifier. Your amplifier, cabinet, and effects are all intended to be replaced by these amps. They often offer a large selection of amp types as well as built-in effects like modulation, delay, and reverb. For guitarists who want a variety of sounds without having to carry about a lot of gear, they make a perfect choice.
The amp head or combo with built-in modelling is another form of modelling amplifier. Similar to all-in-one amplifiers, these amplifiers are made to be utilised with exterior cabinets. Compared to all-in-one amplifiers, they often have fewer built-in effects, but they make up for it with more sophisticated amp modelling capabilities.
There are also hybrid amplifiers, which fuse digital modelling technology with conventional analogue circuitry. For the preamp stage of these amplifiers, tubes or transistors are used, and for the power amp and effect stages, digital processing is used. They’re a terrific option for guitarists who like both the versatility of digital modelling and the warmth and responsiveness of a classic tube amplifier.
Software-based modelling amplifiers are the last type. These operate on your computer or mobile device and function effectively as virtual amplifiers. With the aid of an audio interface, they often offer a broad variety of amp models and effects and can be utilised for live performance or recording.
Modelling amplifiers are a popular option for gigging musicians that need a flexible and portable amplifier since they are frequently lightweight and portable.
But some audiophiles contend that modelling amplifiers don’t have the same warmth and authenticity of sound as conventional tube amplifiers. Additionally, the quality of the processor and algorithms utilised can affect the sound quality of modelling amplifiers, which can be problematic for some listeners.
