MESA/Boogie90s Triple Rectifier Standard 150W Tube Guitar Amp Head - Black Bronco

When MESA/Boogie unleashed the Dual and Triple Rectifiers in 1992, the Triple stood at the extreme end of a new high-gain formula, coupling the Rectifier's massive low end and saturated harmonic character with the authority of a 150W power section. More than three decades later, the MESA/Boogie 90s Triple Rectifier Standard brings that formidable two-channel design back into production, hand-built in Petaluma, California, with the power, feel and unmistakable presence that made the original an icon. Six 6L6 power tubes deliver enormous headroom and percussive low-end impact, while Vintage and Modern high-gain voicings move between thick harmonic saturation and tighter, more aggressive response. Selectable tube or silicon-diode rectification and a BOLD/SPONGY Variac power switch provide deeper control over attack, sag and compression, while a tube-driven series effects loop integrates seamlessly with modern rigs. Finished in classic Standard Dress with a polished aluminum Diamond Plate, black chassis and chrome speed knobs, the 90s Triple Rectifier returns in the form that helped define an era of heavy guitar. Two-Channel Architecture for Focused Rectifier Tone Shaping The 90s Triple Rectifier returns to the focused two-channel architecture of the original, with independent Gain, Treble, Middle, Bass, Presence and Master controls giving each channel its own fully adjustable voice. Channel 1 provides the amp's clean sound alongside the warmer, harmonically rich Variable High Gain “Vintage” voice, while Channel 2 delivers the tighter, more aggressive Modern High Gain voice at the heart of the Rectifier sound. MESA's Channel Style “Cloning” switches add another layer of flexibility by allowing the two channels to borrow each other's high-gain voicing, so either side of the amp can be configured around Vintage or Modern response. That flexibility makes it possible to build contrasting rhythm and lead sounds while preserving the immediate, purposeful layout of the original two-channel Triple Rectifier. Selectable Rectification and Variac Power for Dynamic Control A defining part of the Triple Rectifier experience lies in the ability to reshape not only its sound, but also the way the amplifier responds beneath the fingers. Three 5U4GB rectifier tubes provide tube rectification with natural sag and compression, producing a softer attack and more elastic response, while silicon-diode rectification tightens the feel for sharper attack and more immediate tracking. The two-position BOLD/SPONGY Variac power switch adds another layer of control over the power section: BOLD delivers the amp's full, authoritative response, while SPONGY reduces the operating voltage for a softer feel with greater compression and harmonic bloom. Together, these options let players move from tight, percussive rhythm response to looser, more yielding saturation without changing the fundamental Rectifier voice. 150W Six-Tube Power Section for Uncompromising Authority Six MESA 6L6 power tubes drive the Triple Rectifier's 150W Class A/B power section, providing the immense headroom and low-frequency authority needed to keep heavily saturated tones tight, dimensional and controlled at substantial output levels. That reserve of power gives palm-muted rhythms a forceful, percussive impact while allowing complex chords and extended low-register passages to retain definition beneath layers of gain. A dedicated bias switch also supports EL34 power tubes, shifting the amplifier toward a more mid-forward, aggressive response for players who prefer a different power-tube character. MESA's maintenance-free fixed-bias design keeps operation straightforward with supported tube types, while fan cooling helps maintain consistent performance through demanding sessions and live use. Tube-Driven Effects Loop for Flexible Rig Integration A tube-driven series effects loop gives the 90s Triple Rectifier a dedicated path for delays, reverbs, modulation and other effects that benefit from placement after the amplifier's high-gain preamp. The loop can be assigned as needed and includes a dedicated send control, while a global Output control becomes active when the loop is engaged for convenient overall level management. External switching connections provide additional control over channel and loop functions, and a Slave output with dedicated level control expands integration options for more elaborate live and studio setups. Dual 4-ohm and 8-ohm speaker outputs plus a dedicated 16-ohm output provide flexible pairing with compatible cabinets and multi-cab configurations. A '90s High-Gain Icon With Unmistakable MESA Style Hand-built in Petaluma, California, the MESA/Boogie 90s Triple Rectifier Standard brings one of MESA's most formidable original designs back to the factory floor more than three decades after its debut. Its black chassis, polished aluminum Diamond Plate and chrome speed knobs restore the unmistakable Standard Dress that became synonymous with the Rectifier throughout the 1990s, complemented by black Bronco vinyl, a marine-grade Baltic birch enclosure and rugged steel chassis construction. Beneath that familiar exterior lies the same fundamental combination that gave the Triple its singular reputation: enormous 150W headroom, layered high-gain saturation, percussive attack and deep control over power-section feel. Equal parts sonic force and unmistakable visual presence, the 90s Triple Rectifier Standard returns as a definitive expression of the original Rectifier era.
