01-Gold-RS.jpg Gold-plated Relays & Switches
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.
02-MIDI.jpg MIDI Send & Receive
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 - www.lehle.com features a video to help you.
03-Transformer.jpg Lehle LTHZ transformer
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.
05-Gain.jpg Adjustable Gain
Adjustment of volume or distortion using a gain controller is a vital feature in many situations. The gain controllers 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 performances and transportation.
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 Dual SGoS is the second evolutionary stage of the highly successful programmable switcher for two amps plus tuner. This unit makes it possible to play through two amplifiers individually or simultaneously, either as a stand-alone unit or in a network with other Lehle SGoS switchers. A particularly popular combination is the Lehle Dual SGoS with the Lehle D.Loop SGoS. Programming is as easy and intuitive as you would expect from a Lehle product, and can also be done remotely, using MIDI program change commands.
Hum loops are completely excluded, thanks to electrical isolation of outputs A and B by the Lehle LTHZ high-end transformer. Gold-plated-contact relays, ground switches and phase inverters assure the full, loss-free guitar sound. The potentiometers are in the signal path when output A and B are active simultaneously, and the volume of the two amps can be balanced - producing a third sound you've never heard before! Output T, basically intended for instrument tuners, can also be used for a third amp or for a second channel for amp B, opening up even more potentials.
The gold-plated-contact relays feature active pop-and-click suppression, outputs A and B can be muted for undisturbed instrument tuning. Welcome to the new Duality!

Lehle
My sound was suddenly warmer, clearer and a lot more dynamic, wow ! As if somebody pulled the blanket off my speaker cabinet. If the D.Loop SGoS was only a looper then Ikea is only a small furniture shop with a couple of chairs.

Lehle 3at1, 1at3 & Dual SGoS
Next generation of High-Tech-Signal-Routing : once again Lehle stands out from competitors with the new revised product series.
Something similar in regards of signal integrity, versatile and easy to handle in one, can´t be found anywhere else on the market. Since the Lehle switchers are mechanically super-solid and well made there can only be one conclusion : the price-performance-ratio is very healthy.
