3. AC30
As already stated, the VOX AC15 was a huge hit with the British guitar bands of the late ’50s. However, as the popularity of the AC15 using bands grew, so did their need for a more powerful amp. Sure, the AC15 was loud for a 15 Watt amp - darned loud in fact - but it was no match for 1,000 + screaming fans! Remember folks, back in the late ’50s/early ’60s, guitar amps weren’t being fed through the PA
-that was reserved purely for vocals, the band’s
The fruit of VOX’s labour was unveiled to the world in 1959 - the 30 Watt, 2x12, AC30. Several top British bands graduated up to the AC30 instantly and, within months, one of them had scored a number one single with a stirring guitar instrumental. Not surprisingly, pretty much every other UK act worth its salt imme- diately followed suit and the AC30 became the amp behind the
We’ve modelled the sterling sounds of the AC30’s Normal channel as they definitely encapsulate those classic tones that defined the aforementioned British invasion. Just like its smaller brother, the AC15, the AC30’s Normal channel boasts the bare minimum of knobs - Volume and Top Cut (modelled by GAIN and PRESENCE* respectively).
*CONTROL NOTE: Once again, our PRESENCE control models the “Top Cut” on the original AC30 exactly - except in reverse (“off” = cut) to make it more logical, just like on our AC15 model.
Original’s valve compliment: 4 x ECC83s, 1 x ECC82 in the preamp, 1 x GZ34 rectifier, 4 x EL84s in the power amp.

Even though the AC30 was a runaway success, several artists expressed a desire for the amp to have more tonal flexibility and a pinch of extra gain too. VOX reacted quickly and came up with some clever extra tone circuitry that featured an addi- tional ECC83 valve and was called “Top Boost.”* When “Top Boost” was added to an AC30 it increased the gain of the combo’s Brilliant channel, and added two extra EQ controls, giving the amp three tone controls
NERDY HISTORICAL NOTE: VOX initially called this their “Brilliance Unit” but it quickly became known as “Top Boost.” When Top Boost was first introduced it was only available as a retrofit assembly. Even though this modification was not particu- larly difficult to add, it was beyond most folk (hey, I don’t know about you, but mess- ing around with electricity is hardly my idea of fun!). Consequently, in 1964, Top Boost was fitted to the AC30 as standard.
