Astonishing power and versatility in a compact package.

The Mini Rectifier 25 is not a trendy down-line toy or marketing-derived imitation of MESA/Boogie's Recto. It's a real deal, high-end, handmade all-tube amplifier.

Lurking within the Mini Rectifier's expensive metal chassis lies one of MESA/Boogie's most expressive and nuance-enhancing circuits to date, creating an exciting, adrenaline-producing tone machine. Like its original two-channel forefathers, this Mini version keeps things straight ahead and easy to navigate with two footswitchable channels that each contain two modes. While it looks basic and drives easy, a world of stylistic versatility lives within these two simple rows of controls.

Two Channels and Four Versatile Style Modes

Two independent channels and four style modes deliver everything from sparkling cleans to aggressive fury. The Mini Rectifier's Channel 1 focuses on rhythm sounds, both clean and overdriven. The "Clean" Mode delivers crystal-clear, big headroom rhythm sounds that breathe with rich, warm air on the bottom end. When driven to clip and combined with the 10-watt power setting, this mode misbehaves with real attitude and shines for urgent, yet soulful, blues solo sounds and gritty rock rhythm.
"Pushed" aptly describes what to do with the second mode in Channel 1, and here you'll find the next region of gain. With a more stripped EQ and just enough added drive, Pushed invites aggressive rock and roll rhythm, and crunch styles to the party, and even taunts your mid-gain solo work, especially in the 10-watt power setting.

Channel 2 features the iconic Recto high-gain sounds—the iconic liquid wall of "Vintage" and the aggressive fury of "Modern." Vintage excels at thick, high-gain chording and single-note soloing with an elastic feel and a broad harmonic spread. It has a looser, more organic sound, and the overdrive drapes itself around the notes to create a huge, three-dimensional image.

Vintage solo work is further enhanced by the 10-watt power position. Here, the attack envelope changes and becomes rounder and more voice-like, while upper harmonics recede slightly to create single-note sounds of true beauty. Vintage and 10-watt complement each other in ways that will open new doors for the Recto that were previously only available to more well-behaved or "cultured" amps, as well as surprising current big-power Recto owners who experience for the first time what this power range/wiring style does for a sound they had typecast.

Modern is the opposite in every way. This aggressive mode comes right at you—maybe even for you—with stunning attack and a hi-mid bump that keeps things percussive and tracking with hyper accuracy. It's impressive how much gain is delivered, especially on the low end, with the speed and definition it provides. Suffice to say, Modern is about all things heavy and metal. And while this sound is best demonstrated using the 25-watt power setting, using the 10-watt power setting lets you sweeten the mids and soften the attack for a more forgiving and vocal effect.This creates a great alternate solo voice with a little more punch and dynamic content.

Multi-Watt Power Offers a Unique Rectifier Tone Experience

MESA/Boogie's patented multi-watt power provides dedicated switchable wattage options of 10 or 25 watts per channel, unveiling different power characteristics and colors from its EL-84-based power amp. The dedicated wattage range choices unveil different power characteristics and colors, so it's also fair to call them power "voicing" switches as well.

For this Mini Rectifier, the choice of EL-84 power tubes with their amazing clip characteristics, prompted the MESA/Boogie team to explore the different wiring schemes possible, leading to the 10-watt power mode being wired for triode operation. This "more vintage" wiring scheme sweetens and rounds out the sound, turning what might otherwise be a lower volume version of the same voice, into a more "soulful" Recto experience. The 25-watt setting offers a more bold attack, tighter tracking low end, increased definition and all-out headroom. This setting works great with all the sounds and certainly showcases the mightiness in the Mini Rectifier, shocking unsuspecting players and bystanders alike with power and sonic size. But any time you need to tame this little beast and put a vintage patina of warmth and silkiness around things, just kick it down to 10 watts for a whole different world of Recto expression.

Series Effects Loop for Purists
