“You, like me, are unimpressed by dozens of
controls on a guitar amplifier. You want ONE
knob, and IT SOUNDS PERFECT – right? Well,
this is it. To the best of our capability and
belief, here is an amp you will never have to
mess with. If it sounds great for you today, it
will always sound great. Power up, plug in,
turn up the ONE volume knob, and play. We
hope you love it – the concept and the Amp.
”
– Brian May
The AC30BM is our tribute to one of VOX’s long-
standing ambassadors of rock history – namely
Brian May. Between Brian’s unique style and the
stately arena tone of his wall of AC30s, there is
a
“kind of magic” that has wowed audiences
worldwide for more than 30 years.
Legendary tone
The mainstay of Brian’s tone has been the AC30’s Normal
Channel fed from a small treble/mid boost pedal both
usually played flat out and, of course, Brian’s infamous
home-built guitar – the “Red Special.” Over time Brian’s
equipment has been stripped to the bare essentials and
fine tuned to give him the best and most reliable per
form-
ance without any extra circuitry.
With Brian’
s valued input VOX has created the AC30BM,
which is a re-creation of Brian’s stage amp and boost
pedal set-up, and is a limited edition run of only 500
combos world-wide, never to be repeated.
Enhanced to perfection
To complete the package, and to make it slightly more
versatile, we have built the boost circuit into the amp
itself rather than a separate pedal and made it foot-
switchable. We have also incorporated a 15 Watt switch
on the back panel. The 15 Watt switching circuitry is a
unique VOX circuit that not only changes the number of
output valves that are in operation and the value of the
output cathode resistor that bias the valves, but also
changes the impedance of the output transformer. Many
amps have “
half power
” switches fitted, but none of them
do it this way – the RIGHT way!
The construction of the amp chassis itself is predominant-
ly hand wired using components mounted on turret tags in
the time honored way, although where this is not suitable,
for a variety of reasons (such as the booster circuit), there
is also some printed circuit board construction.
