 June 1, 2021

By  Zen Chung

During the 80s and 90s, solid-state guitar amps were mainly found in beginners' bedrooms, except iconic amps like Roland Jazz Chorus and others. However, this has changed with digital modeling. The use of digital amp models has made it so convincing that it can be hard for even the most experienced and discerning ear to tell the difference between "modeled" sound and modeled thing.

The best solid-state amp tends to be easier to maintain and is more reliable. It is a great choice for musicians who are constantly on the move or if you're looking for a practice amp. They tend to be cheaper, produce clean sounds and come with built-in effects.

Finding the perfect one can seem like a challenge; that's why we reviewed the 5 best solid-state amps in the market and also outlined factors to consider when buying.

Factors To Consider When Buying Best Solid State Amp

a) Power Rating and Volume

When searching for the best solid-state amp, you're looking for one with the right power rating. The key is finding the power rating right for you as you don't want a loud practice amp or a quiet stage one. What's great is that you can get amps with built-in power attenuation nowadays, which allows you to achieve bedroom-level sound with big and loud amps while still getting good cranked tones.

Compared to tube amps, solid-state amps are quieter, given the same power rating. This is because solid-state amps are heavily cranked; hence hard clipping occurs, resulting in aggressive non-musical distortion. In comparison, tube amplifiers that feature a soft clip tend to sound a bit more musical sounding.

It's best to keep in mind that most components in an amplifier play a role in changing the tone and volume. The best solid-state amp is built with quality components hence the difference between a high-end solid-state amp and a high-end tube won't be too dramatic.

If looking for the best solid-state amps for playing gigs in medium to large venues/stages, you'll want to ensure you at least have a power rating of 100 watts. This will ensure you have plenty of range during your gig; thus, your solid-state amp won't be pushed to the breaking point.


b) Tone

Since solid-state amplifiers tend to be more affordable, they have racked up a reputation of having bad sound quality. However, considering many musicians use them, the sound can't be that bad.

With solid-state amplifiers, you can expect clean tones. It also has a quicker response compared to a tube amp. However, tube amps have the advantage of having a higher representation of overtones and a more organic sound.

If you're a pedalboard user, you're likely already to have an array of overdrive and distortion pedals. Hence, all you're looking for is a clean platform to amplify and complement those tones. Tube amps tend to handle distortion better compared to solid-state amps. Hence, depending on the type of player you, it's important to keep in mind the number of channels an amp possesses, especially if you're looking to switch from clean to distortion easily. 

c) Speaker Size

The speaker size is a metric you can use to get an idea of the response an amp will have in different frequency ranges. A smaller speaker (6-10”) is likely to have a clearer voice that emphasizes treble frequencies, while a larger speaker (15”) will be more bass-heavy.

Most amps fall in the middle at 12” because a 12” speaker is generally considered to have a pleasing response across the board.

d) Built-In Effects

If looking for an amp with many built-in effects, the best choice would be to go with a modeling amplifier. Alternatively, you can settle on a reverb. Most solid-state amps don’t have the best built-in distortion/overdrive circuits. The only exception is high-end solid-state amplifiers.

However, most solid-state amps do come with distortion. The distortion will not be perfect, but it is often enough until you get a distortion or overdrive pedal.

Modeling amps are not really necessary for every musician, but their main appeal lies in their versatility.

e) Digital Amps

Leading brands continue to innovate by creating digital and android compatible models which are readily available. They provide the opportunity to evolve as an artist as well as enhancing your music production quality.

The amps also promote connectivity, with some offering apps with access to communities where you can share ideas and discuss effect features in-depth. These are ideal for those interested in exploring how to infuse technology into their artistry.

Some questions to consider when thinking about a digital amp: Do you want it to mimic the look and feel of a vintage valve amp, with just a simple array of controls to navigate? Or would you prefer to navigate menu after menu on an LCD screen, or fire up an app for deep editing via Bluetooth?

f) Type of Guitar Amp

Guitar amps can either be a head or combo. Combo amps combine the pre-amp, power amp, and speakers in a single unit. In contrast, the head requires external speakers to use. The advantage of an amp head is that you're able to run more speakers if necessary.

Frequently Asked Question About Best Solid State Amps (FAQ)

What is the difference between solid-state amps and tube amps?

The key difference between the two is that solid-state amplifiers derive amplification from electronic transistors, while a tube amp uses vacuum tubes (also known as valves). Transistors operate differently from tubes in that they don’t pleasantly distort when pushed to their limit. In comparison, players that prefer a tube amp do because they believe it sounds its very best when pushed to the max.

Other differences include that solid-state guitar amps are best suited for players looking for maximum range. ( aka loud, clean, and undistorted signal). However, without a bit of natural distortion, an electric guitar can sound brittle. Hence they tend to be more popular with bassists and keyboard players than with guitarists.

Solid-state amps tend to be lighter than tube amps; hence many musicians especially gigging ones, tend to value their convenience. While in terms of tone, jazz players often favor solid-state amps as they usually play with no overdrive.
