How many watts does my guitar amplifier need

Stijn Scheper |

Are you looking for a new amplifier, but can't see the forest for the trees with all those different wattages? Then we are here to help you! Check this blog to find out what you need.

Tubes or transistor?

What is important to know is that there is a difference between tube and transistor amplifiers (also called solid-state amplifiers).

You may have heard that tube amplifiers are and/or can be louder than transistor amplifiers, but this is not true in theory. It is true that tube amplifiers sound louder than transistor amplifiers because the tubes in the amplifier distort the sound and can make it sound up to 12dB louder than a transistor amplifier.

Higher wattage means more volume, right?

This is not entirely correct. In a sense, more wattage means more volume, but this isn't the only factor you need to consider when looking for more volume in an amplifier. It is important to look at the efficiency of an amplifier if you are looking for more volume. Efficiency means: converting power into sound. This is expressed in decibels (dB). It is also not the case that if you have a 100 watt amplifier and switch to a 200 watt amplifier, you will have twice as much volume. A standard formula is that as soon as you double the wattage, you gain an additional 3dB. So if you go from 100 to 200 watts, your amplifier is 3dB louder. But this may differ depending on the return.

1 watt

If you want to achieve rock tones at a softer volume, it is best to choose a 1 watt tube amplifier. A 1 watt tube amplifier sounds loud and full in small spaces and will be the perfect option if you want softer volumes. If you're aiming for a clean jazz sound at the highest volume, a 1-watt amplifier probably won't cut it. Also, a 1 watt tube amp will have trouble keeping up with the drums during rehearsals.

Popular 1 watt tube amplifiers:

5-15 watts

If you want a clean sound at a soft level, a tube amplifier of 5 to 15 watts will be a very good choice. You can also use these amplifiers on small stages and rehearsals. They are ideal for this, because they are often compact and light. If you are looking for an amplifier that will still produce pure tones at a higher volume, then you need a higher wattage.

Popular 5 watt tube amplifiers:

20-45 watts

For gigging guitarists, a 20 to 45 watt tube amp is a great choice. They can produce a lot with lower efficiency and they generate rock-ready power amp distortion at higher volumes. A tube amplifier of 20-45 watts will be able to keep up with a drummer just fine. On the other hand, a transistor amplifier will have difficulty with this. If you use a transistor amplifier, this is usually for home (practice) use.

Popular 20-45 watt tube amplifiers:

50-90 watts

If you play jazz or funk, or just want maximum clean sound, then a tube amplifier of 50 to 90 watts is exactly what you need. These amplifiers are also ideal for hard rock and metal guitarists.

5-10 watts

A 5-10 watt transistor amplifier is perfect for guitarists who are just starting out and are on a budget. These amplifiers are especially suitable for home use.

Popular 5-10 watt transistor amplifiers:

15-45 watts

This amplifier is also very suitable for home use. You do need a little more amplifier, because your power is two to three times greater than with a 10 watt amplifier. This means you have less chance of distortion and you can produce a better clean sound.

Popular 15-45 watt transistor amplifiers:

50-90 watts

A transistor amplifier of 50 to 90 watts is approximately comparable to a tube amplifier of 15 to 20 watts, and is therefore suitable for small performances. It can also be used for home use or rehearsals.
