Vox AC15 vs AC30 two classic tube amps

If we talk about the Vox AC30, it is inevitable to think of bands like the Beatles, Rolling Stones, Queen, U2, among many others. The Vox AC30 marked the era of the British Invasion -British Invasion- of bands. After more than 60 years, the Vox AC30 continues to be chosen by musicians of all genres.

However, the Vox AC15 should not be downplayed. This amp, initially called Vox AC1 or AC1 / 15 in reference to watts of power, was the one that started it all. It was the team that fell in love with Hank Marvin from The Shadows, who, needing more power, spoke with Dick Denney, owner of Vox, to make them something bigger than the AC15, giving rise to the Vox AC30. You can see this in more detail in our post of the history of the iconic Vox AC30 and AC15 amps.

Vox AC15 vs AC30: characteristics, specifications, similarities and differences

Both the Vox AC30 and Vox AC15 are two classic tube amps. The models analyzed are two of those currently marketed by the brand and the “standard” ones: the Vox AC30 Custom (AC30C2) and the Vox AC15 Custom (AC15C1). We say standard because there are other versions of both models such as the VR, which is a hybrid version, that is, it has a valve, but fundamentally it is in solid state or transistorized, the version with Celestion Alnico Blue speakers, the Handwired (HW) and others.

Both bring you the British sound that you can hear on hundreds of recordings of the bands from the “British Invasion” to the present day. Both will give you that chimey English tone in two different formats. Thus, in summary, we can say that the big difference is that the Vox AC30 is 30 watts while the AC15 is 15 watts of tube power. But also, let’s take a closer look at the specifications and characteristics of these two emblems of tube guitar amplification.

Vox AC30 vs AC15: specifications and features

Of course, both amps are fully tubeless, both in their preamp and power amplifier. They are manufactured in China for several years.

Here, it is worth mentioning that among its main criticisms it stands out that it is factory equipped with poor quality valves. Therefore, it is recommended to change the valves or tubes for higher quality ones such as Mullard, JJ, GT or Tesla, among others.

Both tube amps feature Celestion Greenback G12Ms that handle up to 25 watts each. But the AC30 has two Greenbacks, while the AC15 has only one. In addition, on its rear panel both devices come with 2 speaker outputs with an impedance selector 8 Ohms and 16 Ohms.

Vox AC30: true bypass FX loop for effects

A difference that can be important if you are playing with many effects such as modulations, the AC30 comes equipped with a true bypass FX loop so that you can connect your effects pedals. This is not provided by the Vox AC15.

Power attenuator

It is worth noting that both combos do not have a power output attenuator. This functionality is only available in the head versions that are the AC30CH and the AC15CH of Custom Head.
