Lehle Sunday Driver SW II

The LEHLE SUNDAY DRIVER SW II is a compact high-end preamp for electric and acoustic instruments of all kinds. Electric guitars, basses, acoustic guitars, but also string instruments (e.g. violins, cellos or double basses) unfold their full sound through this preamp. The switchable version extends the features of the classic LEHLE SUNDAY DRIVER II with a soft-touch footswitch that you can use to switch the pedal on and off.

This LEHLE switch works with a microcontroller and an intelligent true-bypass relay circuit with active switch-over click suppression. It therefore switches the LEHLE SUNDAY DRIVER SW II faster than mechanical switches and is also wear and noise-free. The mushroom-shaped button, which is characteristic of LEHLE products, is mounted in the housing so that it moves smoothly, which means that the force of your foot pressure is only transmitted indirectly by a spring. The circuit board is therefore not exposed to any mechanical stress, which makes the LEHLE SUNDAY DRIVER SW II virtually indestructible and gives it a long service life.

Equipped with a discrete Class A input stage with JFET technology, the LEHLE SUNDAY DRIVER SW II provides you with two operating modes: In operating mode D (=Driver), the incoming signal is amplified completely neutrally. This serves to prevent signal losses that can be caused by long cable runs or effect chains. The signal remains strong and clear and retains its dynamics.

Operating mode S (=Sunday) results in a five times higher input impedance. As a result, details that were previously unnoticed suddenly become audible. As the gain setting on the LEHLE SUNDAY DRIVER SW II increases, the sound takes on an unmistakable, characterful warmth. Signal distortion does not occur at any time; even at the maximum gain setting of +18 dB, the signal still remains clean.

Thanks to its studio-compatible overall dynamic range of 130 dB, the LEHLE SUNDAY DRIVER SW II is absolutely free of background noise. To make full use of the dynamics of your tube amplifiers, the input voltage is rectified, filtered, stabilised and then transformed to 30 V after the power supply socket.

When switched off, the LEHLE SUNDAY DRIVER SW II offers you two different operating modes: In TB mode (= true bypass), the input and output are connected to each other without loss via a relay. True bypass mode is particularly useful if you have a small setup with short cable runs or if there is a treble booster or a classic fuzz pedal behind the LEHLE SUNDAY DRIVER SW II.

However, if you are dealing with long cable runs or elaborately equipped effects boards, a cable driver is the better solution. By operating the LEHLE SUNDAY DRIVER SW II in TS mode (= true sound), it acts as a buffer without amplifying or distorting your signal. The LEHLE SUNDAY DRIVER SW II acts as a sound-neutral cable driver, which practically corresponds to operating mode D with the gain control turned all the way to the left. Thanks to the option of selecting bypass mode, you can optimally integrate the LEHLE SUNDAY DRIVER SW II into any setup and use it universally. And on any other day of the week too...
