Compact high-end, hand-made all-tube 25W amplifier head from Rectifier series that features an expensive metal chassis and Mesa Boggie’s most expressive and nuance-enhancing circuits to date. It features two foot-switchable channels that each contain two modes and while it looks basic and drives easy, a world of stylistic versatility lives within these two simple rows of controls. Two independent channels and four style modes deliver everything from sparking cleans to aggressive fury, while Mesa’s patented Multi-Watt Power provides dedicated switchable wattage options of 10 or 25 W per Channel, unveiling different power characteristics and colours from its EL-84 based Power Amp. The Channel 1 focuses on rhythm sounds, both clean and overdriven. The CLEAN mode delivers sparkling, big headroom rhythm sounds that breathe with rich, warm air on the bottom end. When driven to clip and combined with the 10W power setting, this mode misbehaves with real attitude and shines for urgent, yet soulful, blues solo sounds and furry rock rhythm. “PUSHED” aptly describes what to do with the second Mode in Channel 1 – it offers the next region of gain. With a more stripped EQ and just enough added drive, PUSHED invites aggressive rock rhythm and crunch styles to the party and even taunts the mid-gain solo work, especially in the 10W Power setting. Channel 2 features the iconic Rectifier high gain sounds – the iconic liquid wall of VINTAGE mode and the aggressive fury of MODERN mode. The VINTAGE mode 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 creating a huge, three-dimensional image. The VINTAGE solo work is further enhanced by the 10W 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 10W compliment each other in ways that will open new doors for the amplifier that were previously open only to more well behaved or ''cultured'' amps. It may also open wide the eyes of current big-power amplifier owners who experience for the first time – what this power range/wiring style does for a sound they had typecast. The MODERN mode is the opposite in every way. This aggressive mode comes right at you with stunning attack and a hi-mid bump that keeps things percussive and tracking with hyper-accuracy. It is hard to believe that this amount of gain can be infused and yet still deliver – especially in bass frequencies – with this much speed and definition. Needless to say, MODERN is all about all things heavy and metal. Using the Modern with the 10W Power setting to sweeten the mids and soften the attack here, shows another side to MODERN as well that is more forgiving and vocal, creating a great alternate solo voice with a little more punch and dynamic content. Dedicated Multi-Watt Channel Assignable Power switches choices unveil different power characteristics and colours – so they are really also power ''voicing'' switches as well. In this model, the choice of EL84 power tubes with their amazing clip characteristics, prompted the developers to explore the different wiring schemes possible. This experimentation led to the 10W 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'' amplifier experience. The 25W 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 amplifier, shocking unsuspecting players and bystanders alike with power and sonic size. The amplifier benefits from more than four decades of high performance amp design and the Effect Loop featured in this amp is the result of that experience and expertise. The Effects Loop is wired in series with the dry signal to provide the greatest flexibility with the widest variety of FX devices – this FX Loop circuit, when used with quality FX is capable of providing seamless interfacing with no tonal degradation.
