Marshall MA Series Valve Amp News: In the nineties, Marshall developed their ‘Valvestate’ topologies, simulating ‘all-valve tone’ by placing an actual valve in the pre-amp stage of a solid state amplifier.
In 2001, AVT was born, incorporating ‘Advanced Valvestate Technology’ in an effort to evolve this technology further bringing the true valve tone of iconic Marshall amplifiers even closer to the reach of guitarists who wanted more amplifier for less!
The MA Series removes the solid state pre-amp and power amp sections ever present in Valvestate amplifiers and offer a true all-valve amplifier range within the same price bracket!
All models in the MA range are fully valve powered and deliver that unmistakeable Marshall tone. They are the perfect stepping stone between every guitarist’s first Marshall and one of Marshall's iconic UK built tone monsters.
MA amplifiers are powered using the traditional Marshall mainstays of ECC83 double triode valves in the preamp, and EL34 pentode valves in the power amp. The layout and controls are kept simple, allowing you to explore unhindered the full potential of the all-valve tone within. The amplifier benefits from separate equalisation stages for both the Clean channel and Overdrive channel allowing you to optimally adjust each one without compromising the other. An extra benefit has been provided in the form of a valve driven ‘Boost’ function on the OD channel giving you, for example, a solo boost with more volume and gain. The MA also contains a spring reverb for use with all channels within the amp.
The MA series is designed with the flexible control demanded by guitarists but with a streamlined feature set to keep it cost effective. Whether in your own home or gigging, setting up the sounds and relative levels is fairly straight forward:
Overdrive Channel with the Boost enabled. This mode can deliver the highest gain and offers some real mean Marshall signature grind for effortless soloing or powerful metal riffing. Set all EQ controls and Crunch Balance to 12 o’clock. Turn up the Volume and Gain to get your sound at the required level when playing solos. Fine tune that sound with the EQ including the Presence and Resonance controls.
When you are happy with your ‘solo’ mode then disengage the boost to give you your rhythm or crunch sound. The volume and gain of this mode is further controlled by the ‘Crunch Balance’, (this control does not affect the Boosted mode). The Crunch Balance enables a player to preset the gain/volume difference between their rhythm and solo modes and the key to success is the careful balancing of the Overdrive Volume, Gain and Crunch Balance controls.
