At the core of the Sukhasana you'll find one of the most popular vintage Blues circuits ever built. What was once known as the Black Tooth Grin has been condensed down into a smaller more pedalboard friendly enclosure. Based on the vintage Marshall Bluesbreaker pedal I've bent the circuit to provide the user with a bit more gain and the mod switches which allow you to swap sets of diodes in and out of the stock circuit in order to alter the gain structure of the pedal. I've also added a treble control to help what I feel is a somewhat lackluster tone response of the tone control. These two controls now work in conjunction with each other to help you dial in the exact amount of highs you would like to pass through the signal. The Bluesbreaker tone has been a staple sound of the likes of Eric Clapton, John Mayer and countless others throughout history. The Sukhasana is powered by a 9VDC 2.1mm center negative power supply and is covered by a bumper to bumper one year warranty on parts and labor. Each unit is handmade by yours truly right here in Guilford, Indiana.
