Effectrode Mercury Tube Fuzz Pedal.
The Mercury fuzz pushes vacuum tube technology to its absolute limits for some devastatingly thick and rich fuzz sounds that are not attainable with traditional transistor fuzzes.
This beautiful little pedal is built on a vintage, hand selected, space grade pencil tube and N.O.S. germanium point-contact crystal diodes.
This combination of hot biased and cold-biased tube gain stages with crystal diode clipping circuitry blends thermionic (asymmetrical) and solid-state (symmetrical) distortions to generate beautiful fuzzed guitar tones.
At full throttle this little pedal can generate outrageous ‘blocking-distortion’ which sounds like a tube amp being pushed beyond it’s limits.
Rolling back the ‘Fuzz’ control creates an immense, bold fuzz tone with endless amounts of smooth liquid sustain that stretches notes into infinity.
At lower fuzz settings the Mercury cleans up to produce natural sounding (real!) tube dirt and overdrive with unprecedented clarity and string-to-string definition. It’s an incredibly simple, yet versatile pedal.
