10 Best Mini Guitar Amps 2025 in the UK

The LEKATO Guitar Amp is a compact and portable 5W mini amplifier designed primarily for electric guitarists who need a convenient practice solution. Measuring just 4.2 x 6 x 10.5 cm and weighing 230 grams, it's easy to carry around, making it ideal for musicians on the go. This amp delivers a loud sound despite its small size, which can be particularly beneficial for beginners who need clear audio feedback during practice. With built-in effects such as clean, overdrive, distortion, and reverb, it caters to different musical styles and creative needs. However, users should be mindful of adjusting the volume to avoid unwanted noise when using distortion effects.

The LEKATO amp's 1500 mAh rechargeable battery offers up to 20 hours of standby time and approximately six hours of active use, which supports extended practice sessions without needing frequent recharges. It charges via a convenient Type-C port, although it doesn't come with an adapter. The inclusion of Bluetooth connectivity allows for easy pairing with devices to play background tracks or use the amp as a portable speaker, adding versatility beyond traditional guitar use.

One of the standout features is its plug-and-play capability, enhanced by a 230° swivel plug that adapts to different guitar shapes, making it practical and straightforward to use. However, it's worth noting that this amp is not suitable for acoustic guitars, limiting its use to electric instruments with 6.35 mm jacks. The LEKATO Guitar Amp is a great choice for electric guitarists seeking a portable, feature-rich practice amp. While it excels in portability and ease of use, those needing an amp for acoustic guitars will need to look elsewhere. Its combination of effects, Bluetooth functionality, and decent battery life make it a versatile tool for musicians who value convenience.

The Marshall MG50GFX Guitar Combo Amplifier is a solid choice for those seeking a versatile and powerful practice amp for their electric guitar. With a 50-watt power output, this amp is more than capable of delivering enough volume for practice sessions and small to medium venues. The inclusion of a 12-inch speaker ensures a richer sound, providing depth to your practice or performance.

One of its standout features is the range of built-in effects, including reverb, chorus, phaser, flanger, delay, and octave, which offer a wide palette for creative sound shaping. The amplifier's four channels—clean, crunch, OD1, and OD2—further add to its flexibility, allowing users to explore various tones and styles. The three-band equalizer also allows for precise sound adjustments.

However, the MG50GFX does have some drawbacks. Portability might be an issue due to its 22 kg weight and relatively large dimensions, making it less ideal for musicians constantly on the move. Its reliance on AC power limits its use in locations without easy access to power outlets, although the 3.5mm aux-in and headphone out provide convenient options for silent practice and external audio input. Connectivity is somewhat basic, lacking modern options like Bluetooth, which could be a consideration for those wanting more wireless freedom. This amp is best suited for guitarists who prioritize sound quality and built-in effects over portability, especially for practice or smaller gigs where mains power is accessible.

The Positive Grid Spark GO 5W Ultra-Portable Smart Guitar Amp is a versatile and highly portable option for guitarists. With a 5-watt power output, it provides ample volume for practice sessions and small gatherings. The small speaker size is complemented by advanced computational audio technology, delivering surprisingly rich and detailed sound for its size. Integration with the Spark app offers users access to 33 amps, 43 effects, and over 50,000 tones from the ToneCloud community, making it easy to experiment and find the perfect sound for any style of music.

The Auto Chords feature and Smart Jam capabilities add an extra layer of convenience and creativity, allowing players to jam along with AI-generated backing tracks and get real-time chord suggestions for their favorite songs. Portability is a major strength of the Spark GO, with its compact dimensions (12.45 x 8.38 x 4.32 cm) and lightweight design (1 g). The USB-C rechargeable battery provides up to 8 hours of playtime, making it ideal for use on the go.

Connectivity is straightforward with USB Type C for charging and updates. However, it is worth noting that this amp is primarily battery-powered, so those who prefer a constant power source may need to recharge frequently. Additionally, its plastic construction may not be as durable as some higher-end models. The Positive Grid Spark GO is an excellent choice for musicians looking for a compact, feature-rich amp that excels in portability and sound variety.
