Guitar amp simulation takes the various parts of a vintage guitar amp and recreates them as a model.
Amp simulation is useful for many different applications. When it comes to choosing the best simulator you will usually find that like anything else in life, you get what you pay for. This means that the more a simulator is priced, the better it usually is. Don’t expect a $25 plugin to sound the same as a $2000 effects unit, but at the same time don’t discount the cheaper units until you have tested them. The thing with amp simulation is everyone has his or her favorites. Different simulators respond differently to your playing, so it comes down to which response you like the most.
Based on my own opinions and experience, I’ve compiled a list of 5 simulators which I believe fit into the “best” category. I’ve placed the winner last, in the #1 position.
#5 – Software/Plugin – Brainworx BX Rockrack Pro
The reason I’ve placed VST/RTAS plugins in the last position is because of the pitfalls when used in a live situation. I guess it’s an OK option if you’re playing in a highly professional setting. The majority of guitarists reading this, however, will be playing in clubs, pubs and restaurants where people are prone to spilling drinks and knocking things over. Therefore something fragile like a laptop is a risky manoeuvre in a stage setup.
There are some great plugins (some free) out there, however my pick is Brainworx BX Rockrack Pro. I tested dozens of plugins in preparation for this article, however I considered Brainworx to respond the best to my playing. Keep in mind that different plugins have different responses, so you should test several of them to discover which is right for you. More of my favorites include Waves GTR, Native Instruments Guitar Rig, Peavey ReValver and Amplitube.
#4 – Floor Based Processor – Boss GT-100
The Boss GT-100 features dozens of amp models coupled with cabinet simulation. What this means is that you can run the unit directly to the mixer / PA system, eliminating the requirement for a real amp.
You may be wondering how it sounds. Surely it can’t be as good as a real amp? Wrong. The amp models featured in the GT series are modeled after popular tube-based amplifiers, giving you warm tone with a great dynamic response.
Of course if you’re playing in a full-on rock outfit, you’re going to want the stage monitoring benefits of a real amp. But the Boss GT series makes a great backup option if your amp fails on you.
It can also be used in conjunction with a real amp, offering dozens of stompboxes and effects.
#3 – Modelling Amp – Fender Mustang
The Fender Mustang, which is the successor of the Fender G-Dec, follows in the remarkable tube modelling technology and sounds surprisingly good. It can work great for practicing and even be used in a live situation.
One of the limitations of traditional desktop and floor-based processors is that they require external amplification, for example a mixing desk or keyboard amplifier. What’s great about the Fender Mustang is that it includes a built-in speaker, which interacts with the modelling technology in a way that sounds great.
Fender has set a new standard with their 20-watt, 1 x 8 inch version of the Fender Mustang, which is priced at only $120. Fender has also included the ability to download a preset for almost any type of sound with their Fuse software.
#2 – Rack-mount Processor – Fractal Audio Axe-Fx II
The Axe-Fx is without question one of the best sounding modelers out there. It’s starting to appear in the guitar rig of a handful of well-known guitar players. It’s very common to see the Axe-Fx being used as a send/return effects unit in conjunction with tube-based amplification. This is because the Axe-Fx provides a wide array of high quality effects in addition to some of the most popular tube amps on the market today.
The Axe-Fx is well suited for both studio and live use. It’s also known as being one of the easiest units to operate that’s out there. A nice feature of the Axe-Fx is the ability to be used as an audio interface when connected to a PC via USB, which is great for recording.
#1 – Desktop Processor – Kemper Profiling Amp
And the winner is… the Kemper Profiling Amp. It’s my opinion that no other unit currently beats the sound quality of the Kemper amp.
The Kemper amp is not necessarily a modelling amp. It’s a profiling system that takes a snapshot of your real-life amp in its current state. You can then access your entire rig from a digital platform.
That’s some impressive technology. In addition to this feature, the Kemper also includes a handful of out-of-the-box presets to get you going instantly.
The interface is becoming increasingly popular for studio use amongst great players. You can imagine the benefits of not having to carry around tons of heavy gear.
Further Reading
Very solid lineup. I’d also nominate the DigiTech GSP1101 as a low cost option that still sounds great when loaded with a good set of IRs. I think it bridges the gap between the ultra high end stuff like the Kemper and the cheaper beginner level stuff.
