New Amp For Metal Rockers

MI Audio announce the Megalith Gamma   28-Nov-13

MI Audio tells us that they will be releasing their newest high-gain amplifier, the Megalith Gamma, on December 2nd available direct from and selected retailers. They say that following on from the high-gain Megalith Beta amplifier and Megalith Delta distortion pedal, the 80W Megalith Gamma is set to be on the wish list of every metal rocker. Here's the full details in their own words...

"The Megalith name is quickly forging a strong following in the high-gain community, with the MI Effects Megalith Delta high-gain distortion pedal making a formidable impact in the stompbox world. The new Megalith Gamma is already met with high anticipation and looks to follow in its big brother's footsteps.

The Megalith Gamma is a scaled back version of the Megalith Beta, but with a tough voice of its own. The Megalith Gamma has both Low and High (30W/80W) output modes that provide metal destruction from bedroom to stage! Running off two 6550s the Megalith Gamma can also use other large octal power tubes such as KT88s KT90s, KT100s, KT120s, and other medium tubes such as EL34's (with separate biasing). With two large power tubes and intelligent power-amp design, the big bottom end and punch of the Megalith Beta is still present, whilst also retaining the complex and sophisticated high-gain tone that the Megalith line is becoming synonymous with.

The CLEAN channel is a channel is unlike no other in any high-gain amp. Whilst most high-gain amps can deliver a brutal high-gain tone, flicking to the clean channel leaves most metalheads disappointed. Not with the Megalith Gamma! All the top-end is retained, along with the signature fat bottom end to produce a sweet, full clean tone that most amps are envious of!
The DRIVE channel has three gain modes, and has more gain on tap than most metal amps in the market. Tuning of the brutal gain tone is done via the three-band EQ, EQ SHIFT switch (selectable mid-frequency peak) and the ever powerful CONTOUR control. The CONTOUR (affecting only the overdrive channel on the Megalith Gamma) can go from fat, loose and vintage to tight, scooped and modern with a sweep of the dial! Shared EQ provides functional simplicity and a consistency in tone across both channels.

Place your favourite effects into the Megalith Gamma's active, footswitchable FX LOOP with SEND and RETURN levels allowing for any effects unit or pedalboard to perfectly meld with the molten fury of the high-gain channel or the full-bodied clean channel. This pint-sized pugilist is designed to pack one hell of a punch!"
