Bugera TRIREC - Boutique Style Amplifier Head

The TRIREC from Bugera is a 100-Watt amplifier that can deliver tube saturation at apartment-friendly volumes via a Varipower dial that scales output power from 1 to 100 Watts. It also features three preamp channels, each with a wide array of sound options, internal reverb, a boost option, an FX loop, and three rectifier modes (valve, silicon diode, valve and silicon diode).

Rectifiers convert AC current to DC current providing the power a guitar amplifier needs. Most present day amplifiers feature solid-state rectifiers, which have high power output and tight bass response. But many guitarists prefer valve-based rectifiers, which are known for their "sag" effect - a struck chord doesn't reach its full volume right away, but then quickly blossoms into a classic rock statement. With the TRIREC, both types of rectifier are available in the same amplifier, and simultaneously if so desired.

The three preamp channels each have 3-band EQ, Presence, Volume and Gain controls. Channel 1 delivers a dynamic crunch tone. Channels 2 and 3 provide 3 overdrive modes - classic for blues and classic rock sounds, vintage for more gain for hard rock, and modern for pure metal. Five 12AX7 valves give the preamp stage these tonal variations.

The output stage contains four 6L6 valves with a Varipower dial that allows you to determine the amplifier's output power. This provides the compression and sustain of saturated power valves that can otherwise only be achieved by cranking the amplifier to earth-shattering volumes. There is also a Master Volume knob for controlling overall output, a Boost knob for adjusting the amount of optional volume boost (via the adjoining Boost button or included FSB106A footswitch), and Reverb for adding a touch of digital hall simulation.

The back panel features a Line Out jack with dedicated Level knob for sending signal to a slave amp, as well as Loudspeaker jacks with switchable impedance (16, 8 or 4Ω), making the amplifier compatible with virtually any speaker cabinet. The built-in FX Loop has controls for adjusting the send and return levels separately. You also get 6 external switching jacks that allow channel switching, Boost, Reverb and FX Loop to be controlled by an external switching system. This is where you'll find the input for the FSB106A footswitch that also offers a MIDI IN/THRU connection.
