The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts 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.

Hum loops and phase cancellations can occur as soon as the signal from an instrument is fed to more than one 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 specially conceived for use with these high-impedance signals, preserving instrument tone and the interaction between instrument and amp and eliminating hum loops.
04-No-Hum.jpg No Hum Loops
All Lehle products not featuring an LTHZ transformer and bearing this symbol switch the signal ground parallel 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.
06-Stereo.jpg 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, also suitable for mono operation.
The Lehle Little Dual is the Lehle Dual SGoS's little sister, a maximum signal-fidelity amp switcher for two amps. Both amps are activated simultaneously using the left footswitch, while the right is used to switch back and forth between them. High-intensity LEDs make it easy to read off switching state A or B, or A and B, even under high-power spots.
The centerpiece of the Lehle Little Dual is its high-end Lehle LTHZ transformer, which electrically isolates output A from output B, making history of hum loops - permanently! The Lehle Little Dual features a gold-plated-contact phase inverter and a gold-plated-contact ground switch. The two inputs can also be routed in stereo to outputs A and B, if you use the stereo signal of an effect unit as the input, for example. This also makes it possible to route instruments equipped with two pick-ups, including many acoustic and hybrid guitars, and also double basses, via two amplifier systems - with no complications. These systems can be operated either in alternation or in parallel - without hum, and without sound losses, needless to say! The Lehle Little Dual - small, but so utterly effective!
