When I started playing guitars, I had no idea what an amplifier was. I just knew that it made my guitar sound louder. It wasn’t until I started getting into theory and the different types of amps that I realized there were different types of amplifiers with different purposes.

One type of amplifier is the solid-state amplifier. This type of amplifier uses transistors instead of vacuum tubes. My latest excitement on solid-state amps is all about how versatile they are. I have compared several brands in this article, going through the features in fine detail to get you this list of the best solid-state amps you can get in 2022. It’s more durable and less expensive, but some people say it doesn’t have the same “warm” sound as an amplifier that uses vacuum tubes.

Solid-state amps have been around since the 70s and are the most popular type of amps today. They are used by both beginners and professionals. Many people believe that solid-state amps are the best type of amp for practice because they are relatively inexpensive and have a variety of features.

Benefits of solid-state amplifiers;

  • -They’re more durable and less expensive
  • -Some say they have a clearer sound
  • -Can handle high volumes without distorting

How to use solid-state amps:

-Start by setting all the knobs and switches to their off or neutral position

-Turn on the amp

-Set the volume to a comfortable level

-Start playing your guitar

Are solid-state amps good or bad?

It really depends on your preference. If you’re looking for a durable, inexpensive amplifier with a clear sound, then a solid state amp is a good option. But if you’re looking for an amp with a warm sound, then you might want to consider an amp that uses vacuum tubes.

How do solid-state amplifiers work?

Like any amplifier, solid-state amps take the input sound signal through a circuit board and amplify it to a cutting tone that is thin compared to other tones by tube-based amps.

Amps work by magnifying guitar sounds on two stages, the pre-amp stage and the power-amp stage.

In the preamp stage, the amps pick tiny signals from the guitar to what is known as the line level. At this stage, there is the gain, channels, tone shaping, volume control adjustments, and more.

The second stage is the Power Amplifier stage. It amplifies the preamp sound to a level where the speaker can actually move because it gets really loud. There is no voice or sound toning or shaping in this stage.

Unlike solid-state amps, tube-based amps are more expensive, require more maintenance, and are less durable. On the other hand, they offer a much warmer sound than some guitarists prefer.

8 Factors to consider when picking the best solid-state amp;

  1. -The tone you want to achieve: Pick an amp with the right features that will help you achieve the tone you want. Some brands with very tones are Yamaha, Boss, and Line 6.
  2. -Your budget: Amps can be very expensive, so make sure you pick one that’s in your price range.
  3. -The size of the amp: If you’re looking for a portable amp, then make sure to pick one that’s small and lightweight. Some lightweight brands in the market include Orange and Vox.
  4. -The features: Make sure the amp has all the features you need such as effects loops, line in/out, and more.
  5. Versatility: Solid-state amps are more versatile than tube amps. If you play different genres of music, a solid-state amp might be a better option because it can handle different types of sounds.
  6. How much power do you need?: Amps come in different wattages, so you’ll need to decide how loud you want to be able to play. A higher-wattage amp is ideal for gigging and playing with a band, while a lower-wattage amp is better for practicing at home. Depending on where you plan to use your amp, pick the appropriate one.
  7. -Do you need extra features?: Some amps come with built-in effects or other features that might be useful to you.
  8. Ease of use: Pick a solid-state amp that is easy to use in various situations such as practice, recording, and live performances.

As I finalized this list of my top choices to include in my reviews, I made some considerations to enable me to narrow down what I found to stand out in each of my picks. For example, I provided details of the modeling units to highlight if an amp is using a single housing or has modeled tube amps as well. This combination is becoming common with some claiming it is essential to give you the best sound. I also delved into the different features in each of my picks, such as if they include an effects loop. This might be an important factor for some readers.

I also provided a description of how each amp would work best. For example, the Yamaha THR10X is ideal for those who want a portable and lightweight amplifier.

When it comes to the best solid-state amps, there are a few brands that always come to mind. These are Yamaha, Boss, and Line 6. I’ve had the chance to use all three of these brands and can attest to their quality.

I also highlighted if a brand is a combo model. Combo models are those that include both the preamp and power amplifier in one unit. This is as opposed to tube amps which require two separate units. I also highlighted the head and floor units as some key considerations that you need to be aware of. Head units are those that come with a separate cabinet, while floor units are usually all-in-one designs.
