When it comes to Hearth effects pedals, as with Hearth amplifiers, an all tube design is the path to warmth and richness of sound.
All Hearth effects pedals use Vacuum Tube Only design. Not just a tube buffer or tube signal path added to a solid state circuit. There are NO silicon diodes, NO transistors, NO op amps, NO optical electronics and NO signal processors in Hearth pedals! Even the high voltage power supply in Hearth compact pedals uses a vacuum tube rectifier!
What makes Hearth pedals so unique is a combination of compactron and rectifier tubes, enclosures that incorporate a two piece hinged cast brass lion’s foot switch cover/tube cover attached to a cast aluminium or steel case and true bypass foot switch. Also included with each pedal is an external wall power adapter.
