Get the Lowdown on the Harmony 420 Amp: A Comprehensive Review

Are you on a quest for a new amp that can amplify both your guitar and bass, and not burn a hole in your pocket? If so, then the Harmony 420 amp might be right up your alley. Designed for musicians who like value for money, the Harmony 420 is a relatively new entrant in the market. Here’s everything you need to know in order to decide whether this amp is the one for you.

Design and Build Quality

The Harmony 420 is a solid-state amp with a 120W output. It has a sturdy build, making it suitable for gigging musicians who are on the go. The amp features two channels: one for guitar and the other for bass. You can switch between them using the amplifier’s footswitch, which is sold separately. The design of the amp is modern, with an all-black exterior, and a minimalist control panel, making it easy to adjust settings to your liking. The Harmony 420 also has a built-in reverb, which is a definite bonus at this price point.

Overall Performance

The Harmony 420 amp is an excellent option for beginner and intermediate musicians who are looking for a portable, reliable, and versatile amp. It may not have all the bells and whistles that you would find in some of the higher-end models, but it provides a good sound for the price. A bonus with the Harmony 420 is that it comes with a 2-year warranty, giving you some peace of mind.

Sound Quality

The Harmony 420 provides a range of sound options that would suit players of all genres. The guitar channel has a bright and punchy clean tone, which can be overdriven to give a bluesy tone. The crunch and distortion sounds are not as heavy as some other amps, but that is not necessarily a bad thing, as this allows for greater versatility. The bass channel, on the other hand, provides a deep and punchy sound that can handle even the lowest of notes with ease. Overall, the sound is warm and rich, without being too overpowering.

– Affordable pricing: You won’t have to break the bank to own a Harmony 420.
– Lightweight and portable: The amp’s compact design makes it easy to carry around.
– Versatile sound: The dual-channel feature of this amp allows you to switch between a guitar and bass, making it suitable for both solo performers and bands.
– Built-in reverb: The Harmony 420 includes reverb effects, which is not common in this price range.

– No footswitch: The Harmony 420’s footswitch is sold separately, which is an additional expense.
– No separate EQ for each channel: The amp has a shared EQ, which may be limiting for some users.
– No effects loop: If you’re looking to add effects pedals to this amplifier, you might be disappointed to learn that it doesn’t have an effects loop.


In conclusion, the Harmony 420 amp is a solid choice for those who are just starting out as well as those who are looking for an affordable, yet reliable amp for practice or gigs. It is not perfect, but it is definitely value for money. We hope that this review has given you a better understanding of what the Harmony 420 is all about, and that it has helped you make a decision about whether it is the right amplifier for you. Happy strumming, and happy grooving!
