Valve versus modelling guitar amplifiers


Valve versus Modelling amplifiers


When it comes to guitar amplifiers can a modelling or profiling amp really replace a valve guitar amp? there has always been a debate between the traditional valve amps and the newer modelling amps. Valve amps have been the go-to choice for many guitarists due to their warm and organic sound. However, with advancements in technology, modelling amps such as the Kemper and Quad Cortex have gained popularity. But can these modelling amps really replace a valve guitar amp?

The Advantages of Modelling Amps

Modelling amps offer a wide range of advantages that make them a compelling option for guitarists. One of the key benefits is their versatility. These amps can accurately emulate the sound of various classic valve amps, allowing guitarists to access a wide range of tones without the need for multiple amps.

Another advantage of modelling amps is their portability. Valve amps are known for being heavy and bulky, making them less practical for gigging musicians. Modelling amps, on the other hand, are lightweight and compact, making them easier to transport.

The Sound Quality Debate

While modelling amps have come a long way in terms of sound quality, there is still an ongoing debate about whether they can truly replicate the tone and feel of a valve amp. Purists argue that nothing can beat the warmth and responsiveness of a valve amp, claiming that modelling amps often sound too digital and lack the same level of dynamics.

However, proponents of modelling amps argue that the technology has advanced to a point where the differences are minimal. They highlight the convenience and consistency of modelling amps, as well as the ability to tweak and customize tones in ways that would be impossible with a valve amp.

Factors to Consider

Can a modelling or profiling amp really replace a valve guitar amp ?. When deciding between a modelling amp and a valve amp, there are several factors to consider. Firstly, it’s important to think about your specific needs as a guitarist. If you require a wide range of tones and portability, a modelling amp might be the better choice. However, if you prioritise the authentic vintage sound and are willing to deal with the added weight and maintenance of a valve amp, then it might be the right option for you.

Additionally, budget plays a significant role. Modelling amps tend to be more affordable compared to high-end valve amps, making them a more accessible option for many musicians.


While the debate between modelling amps and valve amps will likely continue, it’s clear that modelling amps have made significant advancements and can offer a viable alternative to traditional valve amps. Ultimately, the decision comes down to personal preference and the specific needs of each guitarist. Whether you choose a profiling amp like the Kemper or Quad Cortex, or stick with a classic valve amp, both options have their merits and can help you achieve the desired sound.
