Lehle Lehle Sunday Driver Sw Ii preamp

The LEHLE SUNDAY DRIVER SW II is a compact, high-quality preamp for all kinds of electric and acoustic instruments. With this preamp, electric guitars, basses, acoustic guitars and other stringed instruments (violins, cellos and double basses) reveal their full sonic potential. This SW version adds a soft-touch footswitch to the standard LEHLE SUNDAY DRIVER II to allow you to turn the pedal on and off. The LEHLE switch uses a micro-controller and an intelligent relay true-bypass circuit with active switching noise suppression. Thus, it operates the LEHLE SUNDAY DRIVER SW II faster than a mechanical switch, all without wear or residual noise. The mushroom-shaped plunger characteristic of LEHLE products is housed in the housing so that the force exerted by the pressure of your foot is transmitted only indirectly through a spring. Thus, the printed circuit is not exposed to any mechanical pressure, which makes the LEHLE SUNDAY DRIVER SW II almost indestructible and guarantees a long service life. Equipped with a discrete class A input stage with JFET technology, the LEHLE SUNDAY DRIVER SW II offers two operating modes: in D mode (for “Driver”), the incoming signal is amplified completely neutral. This is to prevent any signal loss caused by long cable runs or effects processors. The signal remains powerful and clear and retains all its dynamics. In mode S (for "Sunday"), the input impedance is multiplied by five. This helps reveal sound details that were previously imperceptible. When you increase the gain of the LEHLE SUNDAY DRIVER SW II, the sound takes on a distinctive warmth and personality. No distortion appears in the signal. Even with the maximum gain of +18 dB, the signal still remains clean. Thanks to a dynamic range of 130 dB worthy of the best studio equipment, the signal of the LEHLE SUNDAY DRIVER SW II is devoid of any residual noise. To exploit the full dynamics of your tube amps, the input voltage behind the power connector is rectified, filtered, stabilized and then transformed to 30 V. When disabled, the LEHLE SUNDAY DRIVER SW II offers two modes of different operation: in TB mode (for "True-Bypass"), the input and the output are linked together by means of a relay to avoid any sound loss. True-Bypass mode is suitable for small setups with short cable lengths or when a classic Treble-Booster or Fuzz pedal is plugged in behind the LEHLE SUNDAY DRIVER SW II. On the other hand, if you are using long lengths of cable or a pedalboard containing many pedals, the best solution is a line amplifier. In this case, use the LEHLE SUNDAY DRIVER SW II in TS mode (for “True-Sound”) to turn it into a buffer amplifier without amplifying or coloring your signal. The LEHLE SUNDAY DRIVER SW II then becomes a completely neutral line amplifier, which corresponds to mode D with gain knob in the left stop. The possibility of choosing the type of bypass allows the LEHLE SUNDAY DRIVER SW II to integrate perfectly into any configuration and to be universally usable.
