9 Best Mini Guitar Amps Reviewed

We have compiled a list of the best mini amps for guitar available on the market for you. Discover these amazing compact amplifiers which provide incredible sound quality without occupying too much space.

Boss Katana Mini – 7-Watt Combo Amp

Boss Katana Mini is an excellent choice if you want a decent without all the bells and whistles of endless features in a small package.

Pros

• Compact design with amazing sound quality
• Authentic multi-stage analog gain circuit

Cons

• Adapter not included; expensive
• Effects

This tiny powerhouse with a 7W output offers a big sound, thanks to its 1x 4″ custom speaker, advanced hardware, refined circuitry and special components. We were impressed by the rich and full tones produced by the amp, making it perfect for practice sessions and jamming at home or on the go.

We loved how versatile the Katana Mini could be, offering three different amp types: Brown, Crunch, and Clean. The crunch and brown tones delivers an impressive punch, but the clean tone wasn’t as bright as we’d hoped. The amp also features a genuine three-band analog tone stack for natural sound shaping, and the built-in tape-style delay adds an extra layer of ambience to your playing.

Being battery-powered, the Boss Katana Mini is incredibly portable, weighing just under three pounds. It’s great for taking on the go, whether you want to practice in the park or jam with your friends. However, be mindful that it doesn’t come with a power supply and runs on six AA-sized batteries, so make sure you stock up.

Positive Grid Spark GO 5W Ultra-Portable Smart Guitar Amp

A fantastic choice for guitarists looking for a portable, versatile, and feature-packed mini amp.

Pros

• Impressive sound quality for its compact size
• Wide variety of built-in amps and effects
• 8-hour battery life for all-day jamming

Cons

• Could be overwhelming for beginners

We were surprised what the folks at Positive Grid have managed with this small guitar amp. The Positive Grid Spark GO is probably the peak of innovation packed in a tiny box.

Whether you’re playing electric, acoustic, or bass guitar, the Spark GO offers a rich, detailed tone that truly defies its compact dimensions.

The ultimate USP for a recording artist is the seamless integration with the Spark app. The app makes 33 amp models and 43 effects accessible with a tap. This allows you to create custom presets or download more than 50,000 tones from the ToneCloud community.

The Spark app even has an Auto Chords feature that analyzes and displays chords for your favorite songs in real-time.

Another really cool feature is the Smart Jam function, an AI-powered bandmate that listens, learns, and adapts to your playing style. This makes jamming alone a lot more interactive and enjoyable, as you get the feel of playing with a virtual band. 

We don’t recommend the Spark GO for beginners though. The reason being, all the smart features does have a learning curve and may frustrate some. And all those amp models and effects can easily distract you from your practice time – we’d rather have you spend your time in nailing that lick.

Blackstar Electric Guitar Mini Amplifier, Black (FLY3)

The Blackstar Electric Guitar Mini Amplifier is a compact, portable, and versatile solution for players on the go.

Pros

• Incredible tonal balance and feel at low volumes
• Patented ISF for Tonal Variety

Cons

• Intended primarily for guitar use, not bass
• Could have more options for built-in effects

Designed to maintain the same tonal balance and feel of a larger guitar amp even at low volumes, this mini amplifier is great for practicing in small spaces or on the go without sacrificing sound quality.

The classic Blackstar box design delivers a decent output at 3W in a compact size. Besides you’ll get 2 channels – clean and overdrive delivered over a patented ISF (Infinite Shape Feature) –  access wide range of tones from American to British with the turn of a knob. 

Onboard knobs include Volume, Gain, Equalizer (ISF) and tape delay. Input/Output has an instrument jack, MP3 output, headphone output and an RJ45 speaker output

Overall, the Blackstar Electric Guitar Mini Amplifier is a superb choice for those looking for a lightweight, compact, and powerful mini amp for practice sessions, travel, or simply those with limited space. Its performance and design make it a valuable addition to any guitarist’s gear collection.

VOX MINI3 G2 Battery Powered Modeling Amp

Another tiny gem at the lower wattage spectrum yet impressive sound and versatility.

Pros

• Classic look
• VOX Bassilator circuit for powerful, low-frequency tones

Cons

• Effects quality may not be as high as more expensive amps

A battery powered Modeling Amp, VOX MINI3 G2 is usefully versatile with its 11 different amp models and 12 popular effects making it perfect for various instruments and musical styles. Thanks to its compact design, this amp is an excellent choice for those always on the go or if you want a reliable amp for daily practice.

Moreover, the proprietary VOX Bassilator circuit delivers a deep, powerful sound with ultra-low frequencies that hold up even at lower volumes. This feature clearly adds depth without distortion or loss of quality. 

We liked the neat setup of the control panel that makes everything accessible from the top. Besides the amp models and effects knobs you get Gain, Tone, Volume, Inst. Jack, Mic-in, Aux, Phone and more – all in one place. 

The dual power options provide flexibility, as you can use either the included AC adapter or six AA batteries to power the amp. With high-quality batteries, the amp is capable of running for up to 10 hours, perfect for long jam sessions and performances.

Marshall MS2 Battery-Powered Micro Guitar Amplifier

Best micro-size amp that fits anywhere, goes everywhere and an excellent choice for guitarists seeking true Marshall tone in a portable package.

Pros

• Compact and portable
• Battery and mains power options
• Classic Marshall tone

Cons

• Limited volume and sound control
• Slightly weak clean channel

Despite its 1W Output and a 1×2″ speaker, this mini amp delivers the true Marshall tone that guitarists love. Weighing only 0.34 lbs., it’s easy to carry around and perfect for practicing on the go or in your bedroom.

Onboard knob includes Volume, Tone and Channel for Clean and Overdrive – just enough for tiny room practice sessions. 

The amp offers both, a 9V battery and mains power options – no need to carry 6 AA batteries. The clamp on the back is a nice touch – just clamp the amp on your belt and start shredding. However, We suggest using a headphone as the tiny speaker output may fall short for some.

When it comes to performance, the Marshall MS2 provides both clean and overdrive channels with a single tone control. While the clean channel distorts on higher volume, the overdrive channel delivers that classic Marshall sound. 

Orange Crush Mini 3W Guitar Amplifier

This is the second in micro-size amp lineup that we think is worth your pocket besides the Marshall MS2 we mentioned earlier. 

Pros

• Impressive sound range in a small package
• Speaker output for use as an amp head
• Built-in tuner

Cons

• Clean tone is difficult to achieve
• Single channel

At 3W and 1×4″ speaker, this mini guitar amp packs a punch, delivering classic Orange tone for bedroom jamming or warming up backstage. Slightly heavier at 1.7 lbs., the top panel knobs are standard with gain, tone and volume. The versatile and straightforward controls provide a wide range of sound options, from clean and clear to high-gain and heavy.

We liked the built-in tuner which will certainly come in handy for most of you. And the instrument jack also acts and the power on/off button.

The remaining input/output the aux-in and the headphone output. Besides the 9V battery slot is at the bottom and you also get a DC adapter for power source.

However, a few users noted that single channel made it somewhat challenging to lock in a good, clean tone.

In our experience, the Orange Amps Crush Mini 3W Guitar Combo Amplifier Bundle is a reliable, affordable option for those seeking a small, versatile guitar amp with classic Orange tone. 

Donner Mini Guitar Amp Digital

A child among the big legends, Donner nevertheless has a pretty solid offer for guitarists on the market for the best portable amp.

Pros

• 7 amplifier models for various styles and sounds
• Built-in drum machine with 40 patterns for practice
• 3 types of effects (mod, delay, reverb) with easy one-knob control

Cons

• Built-in metronome not very useful
• 1 x 3″ Speaker

The 7 amplifier models offer a wide range of tonal options, making it suitable for various genres and styles, from clean tones to high gain.

The built-in drum machine with 40 patterns is a fun addition, significantly enhancing solo practice and jam sessions. However, we’re not sure of the utility of the built-in metronome with no indicators for the tempo or time signature.

The simple one-knob control for the 3 types of effects (mod, delay, reverb) made it easy to add depth to our sound. The 1x 3″ speaker certainly does the job but falls a bit short to match upto the 5W output the amp delivers. 

On the input/output front you get all that you expect plus bluetooth for connecting your smartphone. Donner also offers 3 power options – Battery, DC and a USB-C port.

For your bedroom practice sessions, Donner offers enough value to be in the running for your final choice.

RockJam 10 Watt Electric Guitar Amplifier

Now, some of you may have the budget for a bedroom amp but still carry hope for a louder amp. For you, the RockJam 10 Watt Electric Guitar Amplifier is a worthy consideration offering powerful sound and versatility.

Pros

• 10 Watt power output for rich and dynamic sound
• Built-in headphone output for quiet practice sessions

At 10W with the choice of a speaker and a headphone,  RockJam amplifier is perfect for bedroom practice, jam sessions with friends, or even small performances on stage. If you’re not a stickler for brands, this amp will do the job in your budget.  

We liked the 3-band EQ, giving control to finely adjust the bass, midrange, and treble frequencies to create your desired sound. 

Also note the amp only offers electric for power supply – there’s no battery or USB options available.

If you’re looking to add some distortion or grit to your guitar sound, this amplifier has you covered with its overdrive and gain controls. However, the lack of onboard effects or tape-delay limits your choices on tonal variety you can get out of the amp.

Think of a really stripped down version for a Guitar amp with pretty basic features but big volume – you get the RockJam 10W amp. If this is all you need then go for it./
