THE HEARTH STONE  
The Hearth Stone amplifier is a unique blend of vintage tube guitar amplifier construction and fresh vacuum tube circuit design.  From the hand wired chassis to the custom made hardwood cabinet.  

The  Hearth Stone has a unique 22 watt cathode biased quad 6AQ5 output section.  The 6AQ5 is a miniature version of the 6V6 and delivers a similar sound but in a smaller package.  True to the guitar amplifiers of the early days, I have used cathode bias for the output tubes as well as a vacuum tube rectifier and no output feedback loop to give that classic dynamic tube sound.

The Hearth Stone does however have a couple of features not found in early amps, without changing the heart of the vintage sound.  A CLEAN / DISTORTION  foot switch that provides additional pre-amp gain for an overdriven sound when the GAIN control is set low or big distortion if the GAIN control is set high.  As well as an FX  IN / OUT foot switch that controls a tube buffered effects loop .

With the Hearth Stone design separate “pre-amp” distortion and “output tube” distortion can
