MESA/Boogie 90s Triple Rectifier 150W Guitar Amp Head - Black Bronco

Some amplifiers do more than shape a guitar tone. They help define an era and a generation of players. When the MESA/Boogie Triple Rectifier arrived in the early 1990s, it answered a growing demand for bigger, heavier and more authoritative guitar tones, delivering massive headroom and a new level of control for modern rock and heavy music. Powered by six MESA 6L6 tubes and rated at a formidable 150 watts, the 90s Triple Rectifier pairs its legendary power section with two fully independent channels, voiced in the iconic Orange and Red modes that became staples of high-gain guitar. This head brings that original Rectifier identity back to life, offering crushing low end, layered harmonics and unmistakable attack in a new build crafted by the talented team at MESA/Boogie using premium materials.

150W of Glorious All-Tube Authority

The 90s Triple Rectifier is built for the moments where headroom is not optional. Its 150W power section is driven by six 6L6 power tubes, giving you the punch and control to stay tight under aggressive palm mutes, detuned riffing, and dense mixes. The extra power is not just about volume; it is about keeping your low end solid, your pick attack immediate and your harmonics layered when you push the amp hard.

Two Fully Independent Channels with Classic Rectifier Voicings

Two fully independent channels let you shape distinct sounds without compromise, each with its own gain, treble, middle, bass, presence, and master controls. Channel 1 covers everything from clean to variable “Vintage” high gain, and it can be set to the modern high-gain voice via the Channel Style switch. Channel 2 delivers the iconic Rectifier “Red” character, with additional flexibility to shift voicings using the same style system. The result is an amp head that can move from articulate cleans to massive, grinding rhythm tones and saturated lead work with quick, musical control.

Selectable Tube or Silicon Diode Rectification

A big part of the MESA/Boogie Rectifier legacy is feel, and this head gives you control over how the power section responds. Selectable tube or silicon diode rectification lets you dial in the response you want, from a more elastic, vintage-style sag to a faster, more immediate attack. Add the two-position Bold/Spongy power switch and you can further fine-tune the firmness and compression of your playing dynamics, whether you want tight tracking for modern riffing or a looser, more expressive push under the fingers.

Gig-Ready Integration for Rigs That Move

The tube-driven series effects loop is built for players who rely on time-based effects, rack gear or complex pedalboard routing, and a global output level control becomes active when the loop is engaged. Around back, you get multiple speaker outputs for common cabinet pairings, plus external switching options for channel and loop control. Meanwhile, a compact one-button footswitch handles Channel 1/2 switching, and the included fitted slipcover makes this head easier to protect between rehearsals, sessions, and shows.

A '90s Icon, Newly Built for a New Generation

In summary, this is the Triple Rectifier for players who crave the power of an iconic physical amp powered by tubes. Built in Petaluma, CA with a steel chassis and a rugged, tour-minded design, it delivers the aggressive footprint that made the Rectifier name a cornerstone of heavy guitar tone. From modern high-gain precision to the raw power that defined the 1990s, this head bridges eras with authority. If your sound calls for tight low end, aggressive mid punch and high-gain impact that stays defined at volume, the MESA/Boogie 90s Triple Rectifier 150W Guitar Amp Head is ready to take its rightful place at the center of your rig.
