Supreme Drive

The Juma Supreme Drive is designed and built to provide guitar players with the most organic and detailed overdrive tones possible.  The circuit is simple and clean and the quality of the electronic components is world-class.

At the heart of the Supreme Drive is Burson Audio’s Supreme Sound discrete dual op amp, with USA hand-made Jupiter copper-foil capacitors and USA-made Vishay Z-foil resistors in the signal path.  As a result, your guitar’s complex harmonic and dynamic details flow through to your amplifier as preserved as possible with the best of today’s audio technologies.

Our pedal is currently offered in two versions at two different price points:

Supreme Drive

$499 USD:  Our flagship model with our custom-designed, extra heavy-duty enclosure that is 5-axis CNC machined out of aerospace-grade aluminum for maximum strength and electromagnetic shielding.  Signal path components include a Burson Supreme Sound dual op amp, Vishay Z-Foil resistors and Jupiter copper-foil/beeswax capacitors.

Essence Series

$329 USD: Our Supreme Drive housed in a Hammond enclosure for a cost savings.  The only component change is the use of copper-foil polypropylene signal capacitors custom-built for us by Jupiter Condenser, and they sound awesome!  Every other component is exactly the same. No 9V battery compartment in this model; external power only.
