​MkIII

mother MKiii

The Mother MkIII builds and redefines the legacy of British High-Wattage sounds with it's expanded tonal range and control. Available in two refined forms: the no-frills, high-headroom Single Channel model - ranging from punchy cleans to vintage bark - or the flexible Dual Channel model, offering a wide spectrum of saturation from edge-of-breakup to thick levels of heaviness. The Mother is tonal bedrock for both guitar and bass alike.

Details

GAIN & TONE SHAPING
​The Single Channel version features Channel A  from the Dual Channel model, great for those in search of the highest-strength pedal platform. This single channel version goes from punchy cleans to vintage crunch with plenty of headroom for even the most towering fuzz and distortion pedals and downtuned instruments. The tone is clear, but never fizzy. This channel strikes a balance between clarity and warmth and highly shapable.​

The Dual Channel version adds a second wide-range Channel B that takes the tonality of Channel A, and keeps on going into higher levels of saturation, from virtually clean, to crunch to thick gain with low noise and dynamics intact. 

​​In addition to the Mother's wide spectrum of gain, its EQ is equally wide-ranging. The flexible EQ section begins with the unique 4-position rotary Depth knob, which sets the overall bass extension, low-mid voice, and low-end breakup characteristics in the front end of the amplifier. 
​
From there, the Bass, Middle, Treble EQ sculpts your tone. The Bass control shapes the low-end voicing set with the Depth, provide controlled deep solid low-end. The unique mid control goes from completely scooped to forward vocal midrange. The Treble controls the overall high-end, and for further control, the unique Absence shapes the the tone from present and searing to dark and fogged-out. ​


EFFECTS LOOP
A new addition is the foot-switchable tube-buffered series effects loop. The loop is transparent and provides an extremely low impedance for driving effects pedals and long cable runs with ease.

​
​
LOUDNESS CONTROL
​The Loudness control(s) transparently varies the overall volume of the amp down to bedroom levels without sucking your tone. And like all of our amplifiers, they are available in 50W, 100W, and 200W versions.
