BUGERA BC30-212
Boutique-Style 30-Watt Class-A Valve Combo

Features
Get Rectied
The power amp works hand-in-hand with
the BC30-212’s all-valve rectier to give you
natural compression and sustain not available
from solid-state rectiers. Put simply, a rectier
converts the Alternating Current (AC) entering
your amp into the Direct Current (DC) it needs.
Most modern amps have silicon-based rectiers
that quickly convert the current, so when you
strum a power chord, it bursts out big and
loud, then decays. But a valve rectier converts
current at a slower rate, which means when
you hit that same huge chord, you still get that
powerful response, but the notes naturally
compress and sustain much longer.
The kind of rectier you choose has a lot
to do with your sound. That’s why we provide
two options on the BC30-212: use a single 5AR4
rectier to deliver bigger-than-life stadium rock;
or plug in a pair of 5U4’s (not included) for a
smoother, more-buttery sound.
Two Degrees of Saturation
The rectier and power amp are the
BC30-212’s heart and soul, respectively, but the
preamp works to predispose your sound to
cleanliness or high-gain grind. When you’re
at your job and your workload is too heavy,
you probably get a bit angry and likely do
a little (or a lot of) griping. Valves work in
much the same manner, except when one of
them is overworked, the sound they make is
often perceived as “totally kick-ass” instead of
“bitching and moaning.”
Bearing that in mind, BC30-212’s rst
channel holds a pair of 12AX7s, the V1 stage
of which creates a parallel triode circuit.
More tubes share the workload, so the
signal it conditions is tamer. Channel 2,
on the other hand, holds a single ECC83A
valve that works in a cascading dual-triode
conguration. The accompanying 6-position
tone switch allows you to dial-in a tone that can
become beautifully disgruntled (or high-gain,
in amp-speak) in a hurry.
