Iconic sounds are often a product of struggle and compromise.  They are unmistakable, genuine and have the potential to leave a mark on society.  They are bold, out of place and larger than life.  They fight back, claim their prize, but never abandon their humble beginnings.

They are the JPTR FX Silvermachine - Dual Gain Stage Fuzz!

The JPTR FX Silvermachine is a hand built boutique effects pedal for guitar and bass with a new interpretation of a time tested attitude.  Featuring two gain stages in a parallel circuit, competing for an unrefined and unbuffered vintage fuzz conquest.  With one shared master volume to keep it simple but never stupid, the Silvermachine’s gain knobs act as a filter, delivering tones that range from sizzling drives to rich, dynamic fuzz.

Pushing the gain stages even further brings out the upper octave, instantly reminiscent of the wild Woodstock days, with a twist of Beatnik club nights and Lo-Fi Psychedelic Garage seances.

The JPTR FX Silvermachine retells Fuzz history in a modern iteration.  Its versatility carries tones between Benders and Faces, but infinitely less compressed and deliberately open in character.

The Silvermachine includes an unfinished metal enclosure that is designed to relic.  With use, the enclosure will rust and wear giving a unique road worn and highly rock and roll appearance.
