Factors to Consider Before Buying the Best Tube Amplifier
1. Sound Quality
The sound quality is one of the most important factors that shouldn't be ignored when purchasing a tube amp. The articulation, dynamics, and clarity of the amp model you choose are important. Many might have different opinions when it comes to sound, and you should check several reviews to determine how good the amp sounds.
2. Amp Tone
Since different amps have different tones or voicings, ranging from subtle to obvious, experts have divided the tube amps into flavors that include British, which emphasizes the punch and mids, as well as American that emphasizes the lows and highs. This has made the description of tonal differences easier.
However, if you're unfamiliar with the amp tones, then the best thing would be to choose one with a similar sound to the one used by your favorite guitarists or check the reviews. Luckily, there are some manufacturers that will produce amps that have multiple voicing, which come in handy if you're looking for sonic flexibility.
The equalizer helps you improve the guitar tone using the EQ controls. Currently, there are pedals and rack effects that are able to accomplish similar equalization with more accuracy.
Ideally, the bigger the size of the speaker, the better it reproduces lower frequencies. However, the bigger is not always the best, especially when you won't be using an amp. For jamming, practicing, and even recording, the medium-sized speakers are good enough and are preferred by guitarists because of their emphasis on mid-range.
5. Power rating
The power rating indicates how loud an amplifier is. Ideally, high power ratings are great for professional use, while low power amps are ideal for practicing. Moreover, some of these amps have a power attenuator that provides you the ability to lower the power output.
Lowering the output comes in handy when you want to customize the amp's volume and also allows you to crank the gain at a lower volume. This is ideal for getting amazing tones without disturbing your neighbors.
Although some people might ignore this factor, it is an important one because the cabinet type might affect the tone produced. Open back cabinets will project the sound to the back and front, producing a more natural sound. They are preferred since they are better at filling stages and rooms.
On the other hand, closed-back cabinets give a clearer and punchier tone and are preferred by sound engineers since they have a great front projection that is easier to mic. Lastly, back-ported cabinets will allow some of the sound to leak through the small ports at the back and are great for low-end emphasis.
7. Input and Outputs
While most affordable tube amps have a single input, there are some that come with two inputs that accommodate different types of guitars or different signal channels. Amps that with multiple inputs add flexibility and may sometimes allow two guitars to use a similar amp.
On the other hand, amp models with multiple outputs are reversed for amp heads, although there are combo amps with extension speaker outs and headphones. A headphone output will provide quiet practice. Some come with direct USB recording that makes the tube amp even more convenient.
In most cases, higher prices won't always mean that the product is of better quality, and the same applies to tube amps. While the best guitar amps can be a bit pricey, there are others that come at an affordable price and are equally great.
However, the bigger the budget, the higher the number of choices you have to find one that perfectly matches your needs and preferences. Luckily there are great tube amps for every budget.
