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 three versions at three 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 v.1

$399 USD:  This version of our pedal has the same circuit as our flagship model.  It is built with exactly the same world-class electronic components, but it’s housed instead in a Hammond enclosure for a cost savings and a slightly smaller footprint to save space on your pedalboard.  There is no internal 9V battery snap inside.

Essence Series v.2

$299 USD:  This is our Essence series pedal with one component change.  The signal capacitors are custom-built for us by Jupiter Condenser using the same oxygen-free copper foil as their beeswax capacitors.  They are an awesome polypropylene capacitor with a slightly more modern sound and offer a further price reduction.
