The finest universal all-tube buffer

for amplified musical instruments!





The SGBB is a true, audiophile quality, vacuum tube pickup driver (buffer/impedance matcher) especially designed for enhancing the tone of magnetic or piezoelectric musical instrument pickups. Originally developed for use with pedal steel guitar, the Black Box is equally effective at breathing life into and enhancing the tone of upright or electric bass, electric or acoustic guitar, mandolin, fiddle, Rhodes or Wurlitzer electric piano, synths and keyboards, drum machines, lap steel guitar, studio mix tracks, and more.



The Black Box's output will easily drive just about any device without subjecting your sound to tone-killing capacitive loads or inadequate input circuits as found in many effect units. The Black Box generates a warm, sweet and musical smoothness that you just can't achieve with the use of transistors or digital modeling devices. It lets your guitar "think" it's plugged directly into the finest tube amplifier and still allows the use of many effect pedals and devices after it.



When used with acoustic pickups, the Black Box does an amazing job of taming that typical hard, brittle, crispy high end, and turns the treble into something much more natural, sweet, and musical. It also works wonders on that frustrating midrange often experienced with acoustic pickups, and makes it far less necessary to resort to heavy and complex EQ notches and filters to get the right sound. The end result is an acoustic instrument that sounds much more like wood and strings, and a lot less like a pickup.



*We also offer a special modification for upright acoustic bass with piezo pickups, that expands the Vari-Z (variable input impedance) range from 1Meg Ohm (traditional Black Box) to 10Meg Ohm, to optimize the pickup response.
