Lehle switches

Lehle Switches are a line of high quality boutique guitar pedal loopers, switchers, buffers, and DI Boxes manufactured in Germany.



Lehle switches have the following features.
Gold-plated relay and switch contacts.
The signal from the pickups of an electric guitar and bass is so weak that poor-quality cables, cold joints and cheap contact m aterials ruin your sound.
Switch contact need to be made of special materials to permit loss-free switching of these low-level signals.
All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.
The Lehle LTHZ transformer.
Hum loops and phase cancellations can occur as soon as the signal from an instrumentis fed to more amp simultaneously.
The one and only remedy for this is a high-quality transformer.
Standard transformers modify the tone of electric guitars and basses very severely, since they are not designed to handle the low-strength high-impedance signals generated by instrument pickups.
The lehle LTHZ, on the other hand, has been specifically conceived for use with these high-impedance signal, preserving intrument tone and the interaction between instrument and amp and eliminating hum loops.
Goodbye to hum loops.
All Lehle products not featuring an LTHZ transformer and bearing this symbol switch the signal ground parrallel to the signal itself via switches or relays with gold-plated contacts.
Hum loops are thus effectively eliminated when switching backwards and forwards between different signal sources without, for example, simultaneous activation of two amps.
Stereo.
Many effects units feature stereo outputs.
Or: instruments frequently have two pickup systems, e.g. a combination of conventional magnetic and Piezo types, to emulate an acoustic sound. Lehle accessories are ideal for trouble-free routing of such dual-channel stereo signals.
All stereo-capable Lehle products are, of course suitable for mon operation.
Transmit and recieve MIDI.
All products in the Second Generation of Switching (SGoS) range are programmable and can be networked with each other via MIDI program-change commands.
External MIDI equipment can also be integrated without difficulty.
Programming is intuitive, and is quick and easy to learn.
Adjustable gain.
Adjustments of volume ar distirtion using a gain controller is a vital feature in many situations.
The gain controller on the corresponding Lehle products feature black anodized aluminium knobs set back into the housing so that they can be easily fingertip rotated but keep their settings during performance and transportation.
18V.
To exploit the dynamics of tube amplifiers to the full, the input voltage of Lehle products bearing this symbol is rectified from the power supply socket, the filtered, stablized and doubled to 18V.
