Vox VALVETRONIX AD50VT - Manual (Page 25)

21
Original’s valve compliment: 5 x ECC83s & 1 x ECC82 in preamp, 1 x GZ34
rectifier, 4 x EL84s in power amp.
6. UK ’70s
This is based on the “High Treble” channel of a 1971, 50 Watt, four input, all-valve
head. This amp was chosen because the tone was incredibly rich and warm yet
biting and distinct! As this amp has no master volume facility, the way to use it to
its full potential is to crank the Volume.
To achieve the same response as the original, turn the VOLUME to maximum
and use the Master Volume to set your desired volume level.
Wind the GAIN control all the way up and immerse yourself in an instantly
recognizable, organic overdrive that responds beautifully to the subtle dynamics of
your playing and dominates “classic rock.” Rolling back your guitar’s volume con-
trol results in a unique and highly usable clean sound.
Original’s valve compliment: 3 x ECC83s in preamp, 2 x EL34s in power amp.
7. UK ’80s
This is modelled on a 1983, all tube, single channel 100 Watt head that boasts a
Master Volume control — a wonderful feature that allows the user to dial in a
decent crunch tone without having to max out the amp’s volume. Invariably played
with its Gain control cranked to the max, this amp was responsible for the fat, roar-
ing sound that dominated ’80s hard rock and heavy metal. In the 80’s this amp
was the only amp of choice...and, for many, still is!
Although UK ’80s became famous for its distinctive, cranium-crushing crunch,
it isn’t merely a “one trick pony” and neither is our model — just like the original,
when you roll back your guitar’s volume knob you’ll get a bright, clean sound that’s
perfect for chord work and will cut through any mix like a hot knife through butter.
Original’s valve compliment: 3 x ECC83s in preamp, 4 x EL34s in power amp.
