Knowing what sets different amps apart will help you find the best amp for your needs and preferences, playing a huge role in the overall structure and sound of your rig!
In this guide, I’ll provide a rundown of every type of guitar amp. We’ll look at how they work, what kind of music they’re suited to, and which one might be right for you. From the trusty solid-state to the tone-mirroring modelling amp and all the valve variety between, by the end of this article, you’ll have everything you need to choose the best guitar amp for your setup!
Key takeaways
To save you scrolling, here’s a brief rundown of the variety of amp types out there alongside some of our top suggestions:
| Amp Type | Description | Recommendation |
|---|---|---|
| Valve | The amp that started it all - valve (tube) amps use glass vacuum tubes to conjure a loud, responsive sound. | Marshall 2525C Studio Mini Jubilee 1x12 Combo |
| Solid-state | Compact and reliable, solid-state amps use transistors (an electronic component) to produce sound. They deliver a clean and consistent tone. | G4M GA-30 30W Guitar amplifier |
| Modelling | The chameleon of the amp universe - modelling amps use digital signal processing (DSP) to emulate the sound of other amps, often cramming several tones and effects into one compact unit. | Boss Katana Mini X |
| Hybrid | A beautiful blend of tube and solid-state technology – these amps capture the reliability of solid-state amps while maintaining the dynamic response of tube amps. | Orange Micro Dark Valve Hybrid Guitar Amp Head |
| Digital | Like modelling amps, digital amps use DSP, although they don’t necessarily replicate the sound of other amps like modelling amps do. Digital amps cover any amp that processes your sound signal digitally. | Laney Lionheart Stereo Bluetooth Mini amp |
Different amp types compared
Valve
Rich, warm, and dynamic in tone. That’s why valve amps are loved by guitarists far and wide.
Using vacuum tubes to amplify your signal, they deliver natural compression, harmonic depth, and that coveted responsive feel. Primarily suited to blues, rock, classic metal, and jazz, valve amps really shine when cranked up, producing rich overdrive and organic breakup.
Valve amps comprise a tube-driven preamp and power amp, often running at high voltages. While they’re heavier and more delicate than solid states, they also have that authentic analog warmth that’s highly sought-after by professionals. Pull up almost any old-school live rock rendition on YouTube and you’ll see stacks upon stacks of pure valve power!
So, Watt’s the catch? (Sorry). Well, valve amps require regular maintenance, as the tubes wear out over time and can be fragile. The general life span of these valves is around five to six years, so you do get plenty of play time before they go kaput!
If you’re looking for recommendations, we’d go for the Vox AC30. This is the rock-‘n’-roll-ready valve amp – it’ll deliver authentic ‘60s British tones straight to your setup. While it’s a tad costly, that’s the price to be paid for era-accurate vintage tones!
Solid-state
Solid-state amps use transistors instead of vacuum tubes. This makes them reliable, lightweight, and low maintenance, and because there are no fragile valves to replace, they’re extremely durable. They’re also affordable – perfect for for beginners or guitarists who simply want to keep their wallet intact!
While solid-state amps lack the natural compression and warmth of their valve counterparts, modern solid-state designs offer impressive dynamic response and clarity.
They produce a clean, consistent tone with minimal distortion, making them ideal for jazz, funk, pop, and much more. An awesome feature of solid-state amps is their high headroom potential, keeping your signal clean even at higher volumes.
If solid-state amps sound like the right amp for you, there’s plenty to choose from. The G4M GA-30 gives you all the essential characteristics of solid-state amps and more, with a footswitch input and a built-in reverb effect to add more expression to your playing.
On the other hand, your ideal solid-state amp might need more effects, a vintage vibe, and greater overdrive potential… Luckily there are amps like the Hartwood Voltair, boasting a beautiful British racing green as opposed to the standard solid-state blacks and greys.
Hybrid
Hybrid amps combine iconic valve warmth with solid-state reliability, giving you the best of both worlds.
They typically feature a valve preamp for natural compression and rich harmonics, while the solid-state power section provides efficient amplification without the hassle of full valve maintenance.
These versatile amps are best suited to rock, blues, and metal thanks to their dynamic response and punchy tone.
To add a blend of valve viscosity and solid-state sturdiness to your tone, the Orange Micro Dark Valve Hybrid Guitar Amp Head will do the trick, delivering high-gain valve-driven preamp tones in a compact, lightweight unit.
Unlike full valve amps, hybrid amps require minimal upkeep, as only the preamp tube will need replacing over time. They’re perfect if you want authentic valve character without the bulk and maintenance of a traditional tube amp.
Digital and modelling amps
Digital and modelling amps are some of the most versatile options out there, using digital signal processing (DSP) to shape and amplify your sound.
They recreate the tones of classic amps, giving you access to an extensive library of legendary sounds, from sparkling cleans to high-gain distortion. Whether you’re into blues, rock, metal, or jazz, these amps provide a vast range of tones to explore.
One of their biggest advantages is their built-in effects, which can reduce the need for a full pedalboard. Chorus, reverb, delay, and even experimental sounds like synth and wah are often included.
And thanks to their lightweight, often compact design that houses a multitude of digital creative possibilities, they’re portable and low maintenance – ideal for home practice and recording.
The main drawback is that no digital amp can perfectly replicate the organic, dynamic response of a traditional valve amp. There’s always a slight difference between a modelled tone and the real thing.
That said, industry-leading modelling amps like the Fender Tone Master Deluxe Reverb capture the essence of ‘60s sound while satisfying modern playing expectations.
The Boss Katana Mini X is another one that showcases the epitome of modern digital amp tech!
Combo vs. stack
When choosing a guitar amp, one of the biggest toss-ups is between a combo amp and a stack.
A combo amp houses the amplifier and speaker in one unit. It’s compact, portable, and easy to set up, making it ideal for home practice, small gigs, and rehearsals.
Many modern combo amps pack as much tonal potential as possible, adding features like effects and Bluetooth connectivity to reduce the need for extra gear. However, they can lack the power and flexibility of larger setups.
A stack, on the other hand, consists of a separate amplifier head and one or more speaker cabinets. These are powerful, customisable, and great for live performances where volume and projection are what you need!
With a stack, you’re given the freedom to swap different heads and cabs to suit your sound and style. You might choose the Marshall DSL20HR 20W Valve Head with Reverb, for example, if you’re after extra reverb potential.
However, while they enhance your projection, stacks are bulky, heavy, and more costly than the humble combo. If you demand as much power as possible and have the means to transport your gear, a stack is the way to go. A good place to start is the SubZero Saturn-50VR Tube Amp 2 x 12″ Vintage 30 Stack; this gives you plenty of power and tonal flexibility at an affordable price.
A note on speakers
Your amp’s speaker plays a huge role in shaping your tone, and the good news is that most amplifiers have interchangeable speakers. This means you can upgrade your sound by swapping out the stock speaker for something that better suits your playing style.
The most common speaker sizes are 8″, 10″, and 12″, with the latter being the standard for gigging and recording primarily in rock, blues, and metal music as they deliver a fuller, more dynamic tone. 10″ speakers are punchy and responsive, perfect for jazz, funk, and country. Finally, 8″ speakers are often found in practice amps, offering a compact, focused sound for intimate smaller scale uses.
Popular brands like Celestion offer a variety of speakers, tailored to different genres. If you want classic ‘British’ crunch, we recommend Celestion’s Greenbacks or Vintage 30s.
Upgrading your speaker is one of the easiest ways to refine your amp’s tone, so if you’re chasing a specific sound, it’s worth exploring the vast range of speakers available. That being said, stock speakers are perfectly fine for most guitarists. For example, the Marshall ORI50C Origin 50W features a 12” Celestion speaker that delivers a classic ‘British’ tone.
Wattage and impedance
Terms such as “wattage”, “ohms”, and “impedance” are important to understand when it comes to perfecting your sound, as incorrectly matching the impedance of your amp head and cab(s) can damage your gear and tarnish your sound.
Wattage determines an amp’s power and loudness. Lower-watt amps (1-15W) are ideal for practice and studio use, while mid-range amps (15-50W) suit small gigs. High-watt amps (50W and above) provide headroom and volume for large-scale playing scenarios, giving you the power and volume to push your sound out to the masses! Wattage also affects clean headroom – higher wattage results in louder clean tones.
Impedance, measured in ohms (Ω), ensures your amp and cab work efficiently together. Mismatching impedance can reduce tone quality or even damage your gear. Most amp heads have a selectable impedance (4Ω, 8Ω, 16Ω). You should always match your cab’s impedance to your amp’s output to achieve the perfect amp sound and avoid damage to your gear.
How to choose the right amp for you
To choose the best guitar amp for your setup, you’ll first want to think about the type of music you play. This massively narrows down the pool of amps you’re sifting through. If you’ll be using the amp for blues and classic rock, you might find that warm, dynamic valve amps work best. Metal, however, benefits from high-gain models with aggressive distortion.
If you’re into jazz, a solid-state amp’s clean response might suit you more.
Size and portability are worth considering too. If you’re playing at home, a small combo amp with built-in effects makes for great company during sofa soloing sessions. On the other hand, if you’re gigging, a more powerful combo or stack setup will deliver the projection you’ll need, giving you the potential to take your music to the masses.
Wattage plays a big part in volume. Low-wattage amps (under 20W) are ideal for home practice, while 20-50W models work well for smaller gigs. If you’re playing larger venues, 50W or more gives you the necessary headroom, with tube amps sounding louder than solid-state models of the same wattage.
Speaker size also affects tone and projection. Smaller speakers (8”-10”) produce a bright, focused sound, while 12” speakers deliver a fuller, bass-rich response. A single-speaker combo is compact and convenient, but a 2×12 or 4×12 cab creates a bigger, more immersive sound.
Build quality matters too – amps with well-constructed wooden cabinets offer improved resonance, while reinforced corners and durable grille cloths add longevity, great if you’re a touring musician who needs a sturdy companion.
Tone and effects are another major factor. Do you need a pure, organic tone, or do you need some built-in effects? To that end, would a modelling amp be better suited to you if you want to experience the tones of various amps?
Of course, there’s always the matter of budget. Solid-state amps are the more affordable amp type, while more advanced and professional players might prefer the sound of a valve amp or the versatility of a high-end modeller. If you’re considering a tube amp, keep in mind that it requires occasional maintenance.
