The Lehle Sunday Driver is equally suitable for
preamplification of both electric and acoustic in-
struments. 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 ef-
fects 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 sud-
denly 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...!
