Django Reinhart played guitar with two only fingers on the left hand due to an early injury. He turned this liability into an asset by inventing new fingering for jazz chords, fingering that inspired the great jazz guitarists that followed and is still used today. The Django transformer line stage also takes a creative approach and eschews unnecessary active components, while still providing +6db of gain and setting a new standard of performance, especially at low listening levels when all the highs and lows are still present in scale. Clarity, dynamics, and tone are finally realized in a passive line stage.
