7 Best Small And Mini Guitar Amps For Practice

If you just want one small amp and don’t want to think about it, get the Blackstar Beam Mini. It’s tiny, it runs for about 18 hours on a charge, and it sounds far bigger than it looks. If money is tight, the Blackstar Fly 3 is the cheapest small amp I’d still buy, at about $65.

This page used to list 15 amps. A few of them aren’t made anymore, one was an amp head with no speaker, and one was an acoustic amp. In November 2026 I cut it to seven small amps you can buy new today, from about $65 to about $520, one for each kind of player. Each one has a demo and the first thing to do when you open the box.

Who Is A Small Amp For?

Small amps are for playing at home, in a dorm, on a desk or out in the yard. Most of them are under 10 watts, which is plenty loud in a bedroom but gets lost next to a drummer.

• If you play alone at home, any amp on this page will do the job.
• If you’ll jam with a band soon, get a 25 to 50 watt practice amp instead. My budget guitar amps page has the Fender Mustang LT25 and the Champion II 50.
• If you want effects, look at picks 3, 4 and 5. The Fly 3 only has a delay and the Marshall only has reverb.
• If you need it silent, pick 2 has no speaker at all. It plugs into your guitar and you listen on headphones.

How I Picked These

I didn’t test these seven side by side. I went through reviews and buying guides from Guitar World, Guitar Player, MusicRadar, guitar.com and Sound On Sound, plus each maker’s manual, and checked that a US music store sells each one new. Then I picked one amp for each kind of player.

1. Blackstar Fly 3: Cheapest Mini Amp Worth Buying

About $65 for two channels, a delay and a headphone jack, running on AA batteries.

Guitar World named it the best budget mini amp in its 2026 guide, and its review said it’s really hard to beat for value. It gets pristine cleans, classic rock crunch and even metal out of two channels, and the delay adds a nice sense of space for practice.

The downsides are what you’d expect at this price. It’s a bit plasticky, it can sound harsh on medium gain without the delay, and a 3 inch speaker has no real low end. Blackstar also makes a Fly 3 Bluetooth and a Fly 3 Charge with a built in battery, if you want those.

First thing to do: buy six rechargeable AA batteries with it, because none come in the box. Then start on the Clean channel with Gain low, and set the ISF knob somewhere between 10 and 2 o’clock, where Guitar World’s reviewer found it sounded best.

2. Fender Mustang Micro Plus: Best For Silent Practice

A pocket amp that plugs straight into your guitar, with 70 presets and Bluetooth, for practice nobody else can hear.

Guitar World called it one of the best headphone amps for electric guitar it had used, and singled out the Fender clean sounds, especially the Twin. guitar.com said it makes a small amp feel big, with an app that’s easier to use than much more expensive modelers.

It isn’t perfect. Guitar World found it could get overwhelmed by a bass heavy guitar with the volume all the way up, and the small side buttons take some getting used to. If you just want the cheapest way to practice silently, the Vox amPlug 3 is about $50. I have more options on my headphone amps page.

First thing to do: charge it over USB-C, turn the volume wheel down, plug it into your guitar and switch it on. Then pair your phone over Bluetooth so you can play along with songs. If it sounds fuzzy at full volume, turn it down a little.

3. Boss Katana Mini X: Best Small Amp With Effects (No App Needed)

Knobs for everything, three good amp sounds, two effects at once and a 10 hour battery, with no phone needed.

Guitar World said that if you want great tones in a small box without relying on apps, this is the mini amp to buy right now, and that it’s one of the loudest mini amps it has tested. Guitar Player picked it as the best mini amp for metal, thanks to the Brown channel. Both liked the headphone sound.

The delay is limited (you can’t change the time or repeats) and there’s no USB recording. It’s also bigger than most minis, about 11 inches wide. It’s on my budget guitar amps page too, as the best battery amp.

First thing to do: charge it fully first (about 3 hours). Boss doesn’t include a charger, so use a phone charger rated at least 5V 2A. Then set Type to Clean and use the Gain knob to go from clean to slightly driven. To play along with songs, hold the Tuner button for three seconds and pair your phone.

4. Positive Grid Spark Mini: Best For Backing Tracks And Learning Songs

The best practice tools of any small amp: it listens to you play and makes up a drum and bass track to jam over.

Guitar World ranks it first in its 2026 practice amp guide, and Guitar Player calls it the best mini amp overall. The Smart Jam feature listens to you play for a few bars and then builds a drum and bass part to play along with. Auto Chords shows you the chords for a song as it plays. guitar.com said it’s simply a great sounding amp, not just good for a small one.

Everyone agrees on the catch: the amp itself has no gain or tone knobs, so you need the app for almost everything. If you like the idea but want to spend less, the smaller Spark GO is on my budget amps page.

First thing to do: download the Spark app, turn the amp on, press the pairing button on the back and update the firmware right away. Then fill the four presets with the four sounds you use most, like a clean, a clean with chorus, a crunch and a lead sound.

5. Blackstar Beam Mini: Best Overall And Best For Playing Anywhere

The small amp that sounds big, with an 18 hour battery and a body that shrugs off dust and splashes.

The Beam Mini came out in May 2026 and went straight to the top. Guitar World made it the best mini amp overall and said it’s much louder than a speaker its size has any right to be. guitar.com said its amp captures were the best sounds it had ever heard from a practice amp. MusicRadar liked that it works fine straight out of the box without a phone.

The single SpeedDial controls everything, which guitar.com found easy to bump into the wrong setting, and you need the app to change amps and effects. The guitar input is on the side, which Guitar World found awkward on a busy desk.

First thing to do: charge it, turn it on and open the Beam app. It connects by itself, so you don’t need the Bluetooth button (that’s only for playing music). In the app, set the cabinet to “In The Room”, which both Guitar World and guitar.com preferred. Hold the Volume button for a second to get the tuner.

6. Marshall DSL1CR: Best Mini Tube Amp

A real all tube Marshall with a 0.1 watt switch, so you can get tube tone at home without bothering the neighbors.

Guitar Player calls it the best tube amp for home and says that if you absolutely must have a tube amp at home, this is your best bet. It’s also the cheapest tube amp Marshall makes. Guitar World found it does everything from a pristine clean to death metal riffing.

Here’s what beginners should know before buying: 1 watt of tubes is loud. Both reviewers found 1 watt too loud for home practice and needed the 0.1 watt switch. The 8 inch speaker also sounds a bit boxy with thin low end, and the reverb is shared by both channels. If you want more tube amps, my small tube amps page has seven, including the Bugera V5 Infinium.

First thing to do: before you switch it on, press the Low Power switch on the back for 0.1 watt. Start on the Classic Gain channel (green light) with the tone knobs at 12 o’clock, then turn the volume up slowly. For silent practice, plug headphones into the Emulated Out on the back.

7. Yamaha THR10II Wireless: Best Desk Amp That Also Plays Your Music

The most grown up small amp here: real stereo sound for guitar and music, simple knobs, a battery and a built in guitar wireless receiver.

Guitar Player put the THR10II first in its desktop amp guide and said it performs well above the “desktop amp” label. Sound On Sound called it a surprisingly mature sounding little combo with real low end punch from such small speakers. It also looks good enough to leave out in the living room.

It’s the priciest pick, and Guitar Player noted the small speakers can struggle with the volume and gain turned all the way up. If you don’t need the battery or wireless, the regular THR10II has the same sounds and Bluetooth for about $370.

First thing to do: turn on Bluetooth by holding the User Memory 4 and 5 buttons together for three seconds, then pair your phone. Use the Audio knob for your music and the Guitar knob for your guitar, so you can balance the two. On battery, expect it to be a little quieter.

What Happened To The Rest Of The List?

The old version of this page had 15 amps. Here’s what happened to them:

• Kept: the Blackstar Fly 3 and the Marshall DSL1CR.
• Replaced by a newer version: the Boss Katana Mini is now the Katana Mini X, and the Orange Micro Dark Terror is now the Micro Dark.
• No longer made: the Line 6 Micro Spider, the Roland Micro Cube GX and the Quilter Mach 2 Combo 8. The Monoprice 611705 is hard to find new.
• Still sold, but on another page: the Fender Mustang LT25 is on my budget guitar amps page, and the Bugera V5 is on my small tube amps page.
• Still sold, but cut: the Yamaha THR5 (older and smaller than the THR10II, and often out of stock), the Positive Grid Spark 40 (bigger than a mini), the Vox Pathfinder 10 (no effects, and often out of stock) and the Fender ’57 Custom Champ (about $1,370).
• Not the right kind of amp: the Fender Acoustasonic 15 is an acoustic guitar amp, and the Orange Micro Dark is a head with no speaker, so you’d need a cabinet too.

How To Choose A Small Amp

• Battery or wall. Six of the seven run on batteries. The Fly 3 uses AAs, and the Marshall needs the wall.
• Knobs or app. The Fly 3, Katana Mini X, Marshall and Yamaha work fine with no phone. The Spark Mini and Beam Mini need the app for most settings, but they give you backing tracks in return.
• Headphones. All seven have a headphone jack, and the Mustang Micro Plus works only on headphones.
• Playing along with songs. Every pick except the Fly 3 and the Marshall has Bluetooth, so you can play music from your phone through the amp.
• Size. The Beam Mini and Fly 3 fit in a bag. The Marshall is 17 lb.

Good luck and keep on rockin’!
