BUGERA TRIREC
Boutique-Style All-Valve Guitar Amplifier Head
Boutique-Style 100-Watt 3-Channel Valve Ampli er Head
with Tri-Mode Recti er, Reverb and Varipower
Valves can be mined for an enormous
palette of tones, but most amps leave
you with just a Master Volume dial and
one choice of valves, making it all but
impossible to experience these varieties at
anything less than titanic volumes. Enter the
BUGERA TRIREC—this all-valve tone bu et
features a Varipower dial that scales output
power from 1 to 100 Watts, giving you sweet
power tube saturation at apartment-friendly
volumes. Feel like experiencing a power
valve variety besides 6L6? Just  ick a
switch and you’re ready to swap them for
EL34 valves (not included). It also features
three preamp channels, each with a wide
array of sound options, internal reverb, a
boost option, an FX loop, and three recti er
modes (valve, silicon diode, valve
and silicon diode).
Tri-What?
Recti ers convert alternating
current (AC) to direct current
(DC), giving your guitar amp the
power it needs to rock. Most of
today’s amps feature solid-state
recti ers, which have high
power output and tight bass
response. But many guitarists
prefer valve-based recti ers,
which are known for their
“sag” e ect – this basically means when you
slam a chord, it doesn’t reach its full volume
right away, but instead makes a tough
initial impact before quickly blossoming
into a classic rock ultimatum. With the
BUGERA TRIREC, both breeds of recti er
are alive and well in the same amp. You can
even use them at the same time! Choose
Silicon Diodes for high power and tight
bass, Valves (2 x 5U4 valves) for lower power
and the almighty “sag,” or a combination
of the two called Valves & Diodes for
medium-powered operation spiked with
equal parts punch and vintage grace.
