Our Top Picks
CXLWZ Electric Guitar Amp 20 Watt Amplifier Portable12.01 x 4.72 x 13.78 inches6.2 poundsCheck on Amazon
If you play a six-string electric guitar, the best pick from this particular list is the 20-watt CXLWZ portable amp, a small combo with a gain control, a headphone input and a noise-reduction cable in the box. A “combo amp” puts the amplifier and speaker in one cabinet, and a practice combo trades loudness for size, a headphone jack and simple controls. One caution up front: four of the six listings here are bass guitar amps, not six-string guitar amps, so they are explained as bass options in their own sections. Guitarists should focus on the 10W mini and the CXLWZ; bass players will find three Fender and JOYO choices that fit.
Quick List
- Fender Rumble 15 V3 – best for bass players who want a small, simple bedroom amp (bass amp)
- Fender Rumble 25 V3 – best for bass players who need more volume for jamming at home (bass amp)
- GLARRY 20W Bass Combo Amp – best for a portable bass practice amp with a headphone and MP3 input (bass amp)
- 10W Mini Rechargeable Guitar Amp – best for quiet, cordless practice with clean and drive channels
- CXLWZ 20W Electric Guitar Amp – best for a louder small guitar amp with a gain control and headphone input
- JOYO MA-10B 10W Mini Bass Amp – best for battery-powered bass practice anywhere (bass amp)
Which One Is Right for You?
| If you… | Choose |
|---|---|
| Play six-string electric guitar and want a little more volume | CXLWZ 20W Electric Guitar Amp |
| Play six-string electric guitar and want cordless, quiet practice | 10W Mini Rechargeable Guitar Amp |
| Play bass in a bedroom or apartment | Fender Rumble 15 V3 |
| Play bass and jam with an acoustic guitarist or drum machine | Fender Rumble 25 V3 |
| Want a bass amp you can carry and run on batteries | JOYO MA-10B 10W Mini Bass Amp |
| Want a budget-friendly bass amp with a headphone and MP3 input | GLARRY 20W Bass Combo Amp |
The first decision is the instrument, not the brand. A bass needs an amp with a speaker and tone shaping designed for low frequencies, and a six-string needs more midrange and top end. Match the amp to the instrument, then choose by wattage, headphone options and whether you want to run on batteries.
All 6 Picks in Detail
1. Fender Rumble 15 V3 – Best for a small bass bedroom amp
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
The Rumble 15 V3 is a bass guitar combo with 15 watts, one 8-inch speaker, a 3-band EQ, an aux input and a headphone output. It is not a six-string guitar amp, and the manufacturer positions it for bass practice. Bass amps use speakers and tone circuits tuned for low notes, which is why a six-string guitar played through one often sounds dull and lacks top-end bite. For a bassist, it is a simple tool: plug in, set volume and EQ, and practice with a backing track on the aux input or in silence through headphones.
A practical tip for bass practice: set the EQ flat first, with bass, middle and treble at noon, then adjust to taste. Small 8-inch speakers can get muddy if the bass knob is turned up too far, and rolling it back a little often makes notes clearer at low volume. Use the aux input for a phone playlist, then plug in headphones when the household goes to bed. It is a tidy first amp for a student bassist.
- Type: bass combo amplifier
- Power: 15 watts
- Speaker: one 8-inch
- Controls: volume, bass, middle, treble (3-band EQ)
- I/O: instrument input, aux input and headphone output
Pros:
- Straightforward controls and a headphone jack
- Aux input for playing along with songs
Cons:
- Not for electric guitar
- 15 watts is enough for a bedroom but not a band
It sits one step below the Rumble 25 V3, which adds wattage for jam sessions.
2. Fender Rumble 25 V3 – Best for bass jamming at home
The Rumble 25 V3 steps up to 25 watts, keeping the 8-inch speaker, and its listing describes it as a beginner bass practice amp. The title also mentions switches, but the visible text is cut off, so confirm which features they control on the product page. More wattage helps when you play with an acoustic guitar, a drum machine or a drummer using brushes. It is still a practice amp, not a gigging rig. Like the 15-watt version, it is a bass amplifier and should be paired with a bass guitar.
Many players stop at the 15-watt version and later wish for more headroom, because a bass needs more power than a guitar to sound clean at the same loudness. The extra 10 watts help notes stay clear when you dig in. If your plan is to practice alone with headphones, the extra power is not essential, and the smaller amp is easier to move. If a drummer or a second player will be in the room, this is the more comfortable choice.
- Type: bass combo amplifier
- Power: 25 watts
- Speaker: one 8-inch
- Controls: EQ and switches, exact functions to confirm on listing
- Use: practice and small jams, not live shows
Pros:
- More headroom than the 15-watt model
- Same simple Fender layout
Cons:
- Bass-only design
- Larger and heavier than mini amps
Pick it over the Rumble 15 if you play with others, and the 15 if you mostly practice alone.
3. GLARRY 20W Bass Combo Amp – Best for a portable bass practice amp
The GLARRY is a 20-watt electric bass combo amp described as portable, with a headphone and MP3 input and volume and tone controls. The listing also mentions accessories, so confirm what comes in the box. It is another bass amp, so it is a match for bassists rather than six-string players. Features like an MP3 input let you play along with songs from a phone or player, and the headphone output keeps late-night practice quiet. It suits budget-minded bass beginners who want a compact amp with basic controls.
As with any lesser-known brand, check the voltage and plug type, the length of the included cable and how the headphone jack behaves before relying on it. A simple test when it arrives is to play at a low volume and listen for crackle when turning the knobs. Return policies exist for a reason, so use them if something sounds wrong. Treat it as a starter amp that can later become a second, portable amp.
- Type: electric bass combo amplifier
- Power: 20 watts
- Inputs: headphone and MP3 input per listing
- Controls: volume and tone controls (full list to confirm)
- Included extras: confirm on listing
Pros:
- Portable with play-along input
- 20 watts for small rooms
Cons:
- Bass-only, not a guitar amp
- Less detail about speaker size and controls in the visible listing
It sits between the Fender Rumble 15 and Rumble 25 in power but offers less published detail.
4. 10W Mini Rechargeable Guitar Amp – Best for quiet, cordless guitar practice
This is a small rechargeable electric guitar amp with clean and drive channels, about six hours of working time and a 3.5mm headphone jack for silent practice, according to the listing. It runs at 10 watts, which is plenty for a bedroom, and the drive channel gives you a basic crunch for rock and blues. The rechargeable battery means you can practice on a couch or porch without a cord. It is a true guitar amp, so it suits six-string players. Exact speaker size and controls are cut off in the title, so confirm them on the product page.
Cordless amps tempt people to practice more, because the amp can sit next to the couch or travel in a backpack. A few habits help: charge before long sessions, turn the amp off between songs to save the battery and avoid leaving it in a hot car. If you are a beginner, the drive channel is a good way to hear the difference between clean tone and distortion without pedals, which can come later.
- Type: electric guitar mini amp
- Power: 10 watts
- Channels: clean and drive
- Battery: rechargeable, about 6 hours working time per listing
- Headphone output: 3.5mm
Pros:
- Portable and cord-free
- Two channels for clean and gritty sounds
Cons:
- Small speaker limits bass and volume
- Battery life will vary with volume and use
Compared with the CXLWZ, it is the more portable pick and the CXLWZ is the louder one.
5. CXLWZ 20W Electric Guitar Amp – Best for a louder small guitar amp
The CXLWZ is a 20-watt portable electric guitar amp with a headphone input, a gain control and a power control, and the listing says it includes a professional noise reduction cable. Twenty watts of solid-state power is useful for practicing with a recording or a drum track in a living room. The gain knob lets you move from clean sounds into overdrive. It suits a beginner who wants a straightforward amp with enough volume to hear the guitar over a backing track. Check the full control list and speaker size on the product page.
With 20 watts of solid-state power, a small amp like this can sound lively at moderate volume, and the gain control gives you a way to practice both clean chords and light overdrive. The noise-reduction cable is a useful detail, since cheap cables are a common cause of hum. If you later add pedals, a small amp with a clean channel gives you a base to build on. Check the speaker size, because a 6.5-inch speaker will sound fuller than a smaller one.
- Type: electric guitar practice amp
- Power: 20 watts
- Controls: gain and power, others to confirm
- Headphone: input listed
- Included: noise reduction cable, per the listing
Pros:
- More volume than the 10W mini
- Cable included in the listing
Cons:
- Fewer published details than the Fender amps
- Not battery-powered as far as the visible title says
It is the louder of the two guitar amps here and the more traditional bedroom-amp format.
6. JOYO MA-10B 10W Mini Bass Amp – Best for battery-powered bass practice
The JOYO MA-10B is a small 10-watt bass practice amp with two channels, and it runs from the included power adapter or six AA batteries. Manufacturer and retailer information describes a 5-inch speaker, volume, tone and gain controls with a drive switch, and a headphone jack and aux input, both 3.5mm. Battery life is about three hours on alkaline cells according to retailer listings, so keep spares. It is a bass amp, so it is for bassists, and it suits a player who wants a portable, quiet practice companion.
Because six AA batteries only last a few hours, many owners will use the adapter at home and keep batteries for travel. The unit is small, about the size of a lunch box, and it has strap buckles on the sides for carrying. As with any mini bass amp, expect the low end to be more of a suggestion than a rumble, which is fine for hearing your notes and fine-tuning timing, but not for filling a room.
- Type: mini bass combo amplifier
- Power: 10 watts
- Channels: two (normal and drive)
- Power source: adapter or six AA batteries
- I/O: instrument input, headphone and aux jacks
Pros:
- Truly portable with battery power
- Two channels for a clean or gritty tone
Cons:
- Small speaker limits low-end depth
- Battery life is short on alkaline cells
It is the bass-world counterpart to the 10W mini guitar amp above.

How We Chose These
This comparison is based on listing research and published specifications rather than on playing the amps. We began with the six catalog entries, noted whether each one is a guitar amp or a bass amp, and then compared wattage, speaker size, headphone options and power source. For the Fender Rumble 15 V3 and the JOYO MA-10B we also consulted retailer specification pages and the manufacturers’ descriptions. Where a listing did not give a value, we marked it “confirm on listing”. Because four of the six products are bass amps, we labeled each one clearly and explained who it fits, instead of presenting them all as guitar amps.
What to Look For
Guitar amp or bass amp: do not mix them up
A six-string guitar and a bass guitar produce very different frequencies. Guitar amps emphasize mids and highs, and bass amps use speakers and tone circuits built to handle low notes. A guitar plugged into a bass amp works but sounds dull and flat. A bass plugged into a small guitar amp is riskier, because the low frequencies can strain a small speaker and cause distortion or damage at higher volumes. Always buy the amp for the instrument you play. If you play both bass and guitar, two small amps cost less than the repairs from pushing the wrong instrument through the wrong speaker.
Wattage and the room you practice in
Solid-state practice amps are surprisingly loud for their wattage. As a rule of thumb, 10 watts is enough for a bedroom, 15 to 20 watts suits a living room with a backing track, and 25 watts is the upper end of practice amps, enough to jam with an acoustic guitar. Doubling wattage does not double perceived volume; it adds only a few decibels. Speaker size matters for tone: a 5-inch speaker sounds small, while an 8-inch gives more low-end body.
Headphone output and aux input
A headphone jack lets you practice silently, which is the main reason to buy a practice amp. Check whether it is a 3.5mm or a quarter-inch jack and whether the speaker mutes when headphones are plugged in. An aux input lets you play along with songs from a phone. Keep headphone volume moderate, because small amps can produce more output than you expect directly in your ears. Start with the volume knob all the way down, plug in the headphones and bring it up slowly. Long sessions at high volume can harm hearing, so take breaks.
Battery and rechargeable amps: safety basics
Portable amps run on AA batteries or a built-in rechargeable battery. Use the charger or cable that came with the amp, charge on a hard, open surface and avoid leaving it charging unattended or in hot places such as a parked car. Do not use a damaged cable or a swollen battery, and replace AA batteries all at once with the same type. Remove batteries if you will not use the amp for a long time to prevent leaks.
A simple way to decide
Write down three facts: your instrument, the loudest situation you will practice in and whether you need to play silently. A six-string player who practices at night in an apartment needs a guitar amp with a headphone jack and 10 watts, such as the mini rechargeable. A bass player jamming with a friend needs 20 to 25 watts and an 8-inch speaker, which points to the Rumble 25. Everything else, such as extra channels, is secondary.
Cables, tone controls and good habits.
A decent instrument cable is the cheapest upgrade you can make. Keep it under about 10 feet for practice, because longer cables pick up more noise. Start with every tone knob at noon, then adjust one at a time. Practice at the level you want to hear, not louder, and take breaks to protect your hearing. Plug in and unplug with the amp volume turned down, since sudden pops can stress a small speaker. Finally, turn the amp off and unplug the adapter during storms or when you leave the house.
Questions
Can I use a bass amp for electric guitar?
You can, but the sound is often dull because bass amps are tuned for low frequencies. If you play six strings, choose an amp designed for guitar.
Can I plug a bass into a guitar amp?
It is not recommended, particularly in small amps, because low notes can strain a small speaker and cause distortion or damage. Use an amp labeled for bass.
How many watts do I need for practice?
Ten watts is enough for most bedrooms, and 15 to 25 watts suits a living room or a jam with a quiet instrument. Higher wattage mainly adds clean headroom rather than a big jump in loudness. Speaker size and cabinet design affect perceived volume as much as wattage does.
Are battery-powered practice amps worth it?
They are handy if you like to practice in different rooms or outdoors, and the trade is a smaller speaker and limited battery life. Keep spare batteries, or charge before long sessions. Avoid mixing old and new batteries in the same compartment.
Why does my small amp buzz or hum?
Common causes are a poor cable, a nearby phone charger or light dimmer, or an ungrounded power supply. Try another cable, move away from power adapters and turn the gain down. If the hum disappears when you touch the guitar’s metal parts, a shielded cable or a different outlet may help.
Do I need a headphone jack on a practice amp?
If you practice at night or in shared housing, yes. It lets you play quietly while still hearing a full tone through headphones.
