Among the different types of guitar amp out there, the tube (or ‘valve’) amp is king. But anyone who’s ever owned one will admit they’re not always the easiest or cheapest things to run. The tubes wear out over time and can be unreliable due to their fragility.

Despite all of this, people still often prefer them over solid-state amps, due to the rich, natural tone they produce. What if you could get the vintage tone of a valve/tube, without lugging heavy, potentially unreliable kit around? Well, now you can, with a multi-functional, lightweight modeling amp.

So which is the best modeling amp? Here’s a sneak peek of the models we review further down this article. Unless you’re in a mad dash, we recommend you read the whole article to make sure you make the right choice.

Here’s what we’ll cover.

What is a Modeling Amp?

A modeling amp is a combo amplifier that models itself and it’s tone capabilities on the sound of classic guitar amps. On one of these amps, you find presets that mimic the sounds of well known, classic amp tones from the like of Fender, Marshall, and Mesa.

They are the ultimate amp for the 21st century. In contrast to valve and solid-state amps, they do everything digitally through the use of what are known as ‘virtual element’ or ‘digital modeling technology’.

As a result, they can replicate a variety of different amplifier tones (known as ‘amp models’) without any of the challenges that real amps face – such as overheating, excessive weight, etc. – and in many cases, perform almost as well, so in many ways, they’re the best of both worlds.

Many years ago, the thought of accurately emulating the sound of a classic amp was unthinkable. You needed the actual gear to get the tone. Not these days.

The best guitar amps can imitate the response accuracy remarkably well. Rather than the antiquated circuit boards or vacuum tubes that were prone to malfunction, these amps use modern circuitry boards that give you the sounds of your favorite amp at the twist of a dial.


So what are the additional benefits to owning one of these? Let’s take a look…

More Versatile

Because there are so many options, the repertoire at your fingertips becomes instantly more versatile. This is a massive benefit for session or gigging musicians, who may want a variety of tones at their disposal, without having to mess about with on stage with gear.

These amps also act as ‘a gateway amp’: you can use one to work out which amp tone you like the most. Sort of like a taste test, giving you the opportunity to hear what many classic amps sound like without having to invest heavily.

Great Value

Cost is a big attraction here. They’re often cheaper than solid-state amps, and always less expensive than valve amps. Granted, they don’t quite offer the quality of tone that a real valve amp gives you, but when you consider that you’re getting multiple tones in a relatively small, lightweight box, it’s impossible to argue with the value for money.

Weigh Less

If you’re a gigging musician you’ll know all about the weight issue of vintage combo amps. They mostly weigh an absolute ton! These combos weigh significantly less than the real thing. You can expect to find them weighing between 30 and 40 lbs, whereas amps containing tubes typically weigh A LOT more.

More Reliable

Finally, thanks to their modern circuitry, modeling amps tend to be a lot more reliable as there is a lot less to go wrong in them.

Buyer’s Guide – Key Considerations

Number of Models

First up, as you probably guessed, is the number of amp models. Some products include ninety-plus replications, while others contain as few as six.

If versatility is your aim, you will want to go for something which can model a vast number. If you prefer a fat rock sound, one which has a Marshall option will be best suited to your needs. If you want a brighter tone, the sounds of Fender are more appropriate. Fortunately, most of these products include classic Marshall and Fender sounds.


Many of these guitar amplifiers contain built-in digital effects, from delay and reverb to phasers, flangers and beyond.

These can be really useful for those who want to experiment with weird and wonderful sounds and get creative and experimental with their guitar playing. These built-in effects are usually favored by beginner/intermediate players, rather than professionals, who may prefer to use a combination of individual foot pedals.

Playing Gigs

If you want to use more than one amp model per gig, getting a product that’s footswitch compatible is a must. These footswitches allow you to stamp your way through settings, in times when it would be impractical to fiddle with knobs. If you sing or would like to use it with a singer, it’s important to look for one with an XLR input to cater for this.

Effects Loop

Some amps have an effects loop. This is an input/output that allows you to insert effects in between the preamp stage of amplification and the power section of the amp. It sometimes works better to fit your effects after the tone has been shaped, i.e., after the pre-amp stage. Having this option gives you greater control over your sound, and allows you to create interesting sonic landscapes.


As these are modern devices, they often contain USB inputs. They can be used to hook up software to edit your sound, or even in combination with your recording software. They’re beneficial to anybody who wants to alter their preset sounds.

Authentic Valve Sound

You can find some amplifiers which include real valves. With these, you get that natural controllability over dynamics and tone that valve enthusiasts love. These amps are on the pricier side and need a bit of maintenance as the valves need to be maintained just like on a standard valve amp.

Product Round-up & Mini-Reviews – Best Modeling Amps

Now you know what you’re looking for, we’ve taken our pick of the top units available on the current market. To make it easy for you to decide which one is best suited to you, we’ve listed the features of each and highlighted the pros and cons.

VOX VT40X Valvetronix

VOX VT40X Modeling Amp, 40W

Check Price on Amazon

The first on our list is the VOX VT40X Valvetronix – it’s a bit special as it includes a real valve. This gives it superior controllability in terms of dynamics and tone, plus all of the benefits of a modeling amplifier.

The Vox has a 10-inch speaker, which brings out high tones, as well as 11 amp models, which can be expanded using ‘Tone Room’ editing software. There is also a USB to allow you to connect to a PC or another device. Many effects are included in this amp, from phaser to distortion to delay and even tremolo.

These effects can be triggered with a footswitch, making it perfect for live performance, and at 40 watts it is more than capable of producing enough sound for a pub or club gig.

The presence of the valve does mean that it requires maintenance, and is slightly more expensive than purely digital products. However, this one is ideal for those who want something that’s ‘real’ but has a few more modern options.

It’s great for those who want more of a hybrid option, and of course for fans of Vox. It’s not ideal for those who are on a budget and want something to try out an array of sounds, as the number of models is quite small.


  • Contains a real valve, enabling extra dynamic and tonal control.
  • There are 11 models – which can be increased using the software – and effects including chorus, distortion, tremolo, and delay.
  • At 40W it’s suitable for both practice and small gigs.


  • The tube components will need maintenance and make it quite heavy.
  • The selection of models is relatively low compared to other products.
  • It needs to be used in combination with ToneWorks software, which might not suit those who prefer working with hardware.

It is also limited to electric and acoustic guitars, as there is no XLR input for microphones and it’s not well suited to bass guitar.

It will suit the creative guitarist who wants access to a vast amount of sounds, the smaller models are perfect for practicing with at home. It might not be suited to those who are more interested in recreating specific, classic tones.

  • Built-in tuner, metronome and drum loops are perfect for practicing with at home.

  • Needs the Line 6 Relay G10T to customize and tweak the sounds truly, and the additional accessory needed for this is expensive.

  • There’s a built-in chromatic tuner, metronome, and looper.

Roland CUBE Street EX

Roland CUBE-ST Street Battery-Powered 5-Watt Stereo Amplifier,Black,medium

Check Price on Amazon

The Roland CUBE is an extremely portable machine. It can run at 50 watts for several hours off just eight AA batteries. You can also reduce the wattage and run for even longer – on power-saving mode – at 25 watts or 10 watts. The maximum amount of time you can use this for on eight batteries is 20 hours!

It’s perfect for the musician who wants to amplify both a guitar and vocals and perhaps even drum machines. Its functionality makes up for its lack of options when it comes to emulating other amps. It wouldn’t be so great for the musician who wants to discover and experiment with a vast amount of valve amp sounds.


  • It can be entirely battery-powered, which makes it extremely portable.
  • It is compatible with vocal mics and instruments such as drum machines, as well as electric or acoustic guitar.
  • There are built-in effects that can be triggered using a foot pedal, making it performance-friendly.


  • It costs a bit more than many on this list.
  • There are only 4 models, so it’s not the best one for experimenting with or learning about different sounds.
  • There are no USB or Bluetooth outputs, so it’s less compatible with modern devices than some of the amps on this list.

So, Which Should I Buy?

If you’re looking for the best amp modeler with the maximum amount of amp models, the Line 6 or the Peavey are the obvious choices. The Peavey also contains a looper, controllable by a footswitch, which is perfect for those who like to get creative in their practice sessions.

If you’re looking for something which sounds truly like a real valve amplifier, then check out the VOX Valvetronix. This hybrid gives you the best of both worlds, with that unbelievable Vox tone.

The Fender Mustang III will catch the attention of Fender aficionados as it allows you to access the sounds of many classic Fender tones, at a fraction of the cost.

Finally, the Roland CUBE is an excellent budget choice for those who combine their guitar skills with singing or programming drum machines.
