The Lehle Sunday Driver is equally suitable for preamplification of both electric and acoustic instruments. This preamp allows electric guitars and basses, acoustic guitars, and also other stringed instruments of any type (e.g. violins, cellos and double basses) to show their full sound coloration. The Lehle Sunday Driver is a handy, compact format high end preamp.
Equipped with modern JFET circuitry, the Lehle Sunday Driver features two alternative modes of operation: in mode D for “Driver“ (switcher pressed), the incoming signal is amplified totally neutral, i.e., with absolutely no modification, to eliminate the signal losses which can occur as a result of long cable runs and effects cascades. The signal is kept strong and clear, and retains its full dynamics.
Mode S for “Sunday“ (switcher not pressed) features a quadrupled input impedance; previously hidden details now suddenly become audible and, as gain increases, the sound takes on the unmistakable, characteristic warmth that gives the Lehle Sunday Driver its name a sound as mellow as a warm Sunday afternoon! There is no signal distortion at any time, and the signal remains clean even at the maximum gain setting of 15 dB and thanks to its studio-quality signal-to-noise ratio of more than -100 dB, the Lehle Sunday Driver is totally free of background noise. A high-quality switch
featuring gold-plated contacts is used to select the required mode.
To permit exploitation of the dynamics of tube amplifiers to the full, the input voltage is rectified, filtered, stabilized and then doubled to 18V after the power-supply socket.
The compact format of the Lehle Sunday Driver opens up a large range of potential applications for this new preamp: it can be used, for example, as a cable driver for large stages, or in complex effects set-ups. In the studio, it is used, thanks to its wide transmission range of 20 to 100,000 Hz, as a recording preamp. The Lehle Sunday Driver is universally utilizable, whether operating as a battery-powered stand-alone device, or integrated into an existing pedal board and not just Sundays, any other day, too...!
