10 Best Acoustic Amps 2025 in the United States

The Positive Grid Spark 2 is a versatile 50W guitar practice amp that caters to electric, acoustic, and bass guitars. It boasts powerful sound quality thanks to Sonic IQ Computational Audio and premium angled FRFR speakers. The built-in Creative Groove Looper with hundreds of drum patterns adds a lot of value for practicing musicians, allowing them to play along with different beats.

AI features are impressive, enabling users to describe their desired tone and get automatic suggestions, which is great for those looking to experiment with sound without extensive manual adjustments. Moreover, the amp models powered by upgraded DSP and new tube emulation ensure rich, authentic sound quality. For those seeking portability, it can play up to 12 hours with optional battery power (battery sold separately), making it suitable for practices on the go.

Though the amp is a bit heavy at 12.1 pounds, its robust metal build promises durability. However, the amp might be overkill for beginners due to its advanced features and higher price point. It is more suitable for intermediate to advanced players who will appreciate the range of functionalities. This makes it an excellent choice for those seeking a high-quality, feature-rich acoustic amp for practice and performance.

The Fender Acoustasonic Guitar Amp is a solid choice for acoustic guitar players looking for a reliable and quality amplifier. With 40 watts of power, it provides enough volume for small to medium-sized gigs or practice sessions. It features two 6.5-inch speakers, including a unique 'whizzer' cone that helps enhance the tone and projection, giving your acoustic sound a nice natural feel. The amp offers two front-panel inputs—one for your guitar and another XLR input for a microphone—making it versatile for solo performers who might want to sing or speak through the same amp. It also has built-in chorus and reverb effects, which add ambiance and depth to your sound without needing extra pedals.

The size (about 18x10x15 inches) and weight (almost 20 pounds) make it somewhat portable, but it’s not the lightest option if you often carry your amp around. The build quality reflects Fender’s reputation, promising durability and backed by a 2-year warranty. If you need more powerful amplification for large venues or bigger speaker sizes for stronger bass response, this might feel a bit limited. While the effects are useful, they are basic compared to some amps with more extensive feature sets. This amp suits acoustic players who want a dependable, easy-to-use amplifier with good sound quality and modest portability.

The Fender Mustang LT25 Guitar Amp is a solid choice for guitar players, especially beginners. With a power output of 25 watts and an 8-inch speaker, it delivers crisp and clear sound quality, fitting well for practice sessions or small gigs. One of the key strengths is its user-friendly interface, featuring a 1.8-inch color display that makes navigating through its 30 preset effects straightforward. This variety allows players to explore different sounds and styles, which is ideal for those looking to experiment with their music.

Portability is another advantage; weighing just over 15 pounds and with its compact dimensions, this amp is easy to transport, making it perfect for musicians on the go. Additionally, the USB audio interface is a nice feature for recording, letting users connect easily to their computers for home recording sessions.

There are some drawbacks to consider. While the 25-watt output is sufficient for small venues, it may lack the power needed for larger performances. Additionally, while it offers many effects, more advanced players might find the presets somewhat limiting compared to higher-end models. The build quality is generally good, but being primarily wood, it may not withstand heavy wear and tear as well as more rugged options.
