If you are on the look for tube amps, you’ll surely come across Vox. The Beatles, Queen, and the Rolling Stones are among the famous musicians who used Vox AC30 guitar amplifier. So, no wonder, it’s among the popular choices of many, particularly the Vox AC15 vs AC30. This article will discuss these amplifiers, as well as give more information on why they are the choice for these legends.

Vox Tube Amps Overview

Founded in 1957, Vox is a musical equipment company based in England. Aside from its famous amplifiers, Vox also makes wah-wah pedals and some electric and bass guitars. A year after its foundation, the 15-Watt Vox AC15 was launched. This smaller amp was being popularized by the English instrumental rock band The Shadows and other rock ‘n’ roll musicians.

In 1959, the bigger (younger) and more powerful brother Vox AC30 came with the request of The Shadows. Basically, the Vox AC30 is just a double-powered AC15 that has 12-inch Celestion Greenback or Alnico Blue speakers.

This article will particularly discuss the Custom version of both AC15 (also known as AC15C1) and AC30 (also known as AC30C2). The former boasts a 15-Watt single 12-inch Celestion G12M Greenback Speaker, while the latter uses the power of the two 30-Watt 12-inch Celestion G12M Greenback Speakers.

Vox AC15 vs AC30: Performance

From the dimensions and weight specified in the table above, it’s no question that the AC30 is not only bigger in terms of the power output, but also on its size and weight. It’s heavier than the AC15, which is a consideration if you want tube amp you can carry around. Though it’s not that big, its size is noticeably taller than the AC15.

Of course, the AC30 is certainly louder with the Greenback speakers compared to the AC15. Though the AC15 doesn’t have the silicon rectifier, so you won’t get that “sag” feel when you crank it up. Some players may like that because it creates a certain amount of compression, but it also has a drawback like the “ghost” notes.

Both Vox amps are gigable, but you might need to use a microphone for the AC15 to produce clean tones, which you can easily get from the AC30 because of the added headroom. Performance-wise, they are at par, especially that they have almost the same features, except that the AC30 has additional controls and I/Os.

Vox AC15 vs AC30: Sound

These two have slightly different voicing. If you want to have clean sounds even at louder volumes, you might need the AC30. For a crowd of around 300+ people without an in-house PA system, the bigger and louder one will surely suffice. The two speakers and four tubes give richer and more complex sound output.

On the other hand, if you’re not concerned with the loud and clean tones, but instead a more focused and tamed response, the AC15 is perfect for you. This YouTube video will help you distinguish the difference between these two amps in terms of tonality:

Vox AC15 vs AC30: Price

Given that the AC30 has more power, inputs/outputs, and controls, it’s more expensive than the AC15. Of course, with the more expensive price tag, you’ll get more headroom and enjoy louder volumes perfect for a bigger crowd. You already know the difference between the two in specifications, performance, and sound, so it’s up to you to spend more on an AC30 or just spend around half of the price of an AC15.

It’s bigger, heavier with more headroom and more control over your music. Additionally, it’s also more expensive compared to its smaller, yet, older brother.
