Lehle D. Loop SGoS Effects Looper / Switcher Pedal

The Lehle D.Loop SGoS recommended as the centerpiece of your pedal-board management system, a programmable double looper that takes inactive effects out of the signal path. The loops can be used independently of each other. An adjustable buffer is additionally available in every situation and - because not all effect pedals have a volume controller - can even be used to boost them when necessary. The high-end buffer boost has gain margins of up to 12dB and can also be used seperately!
The jack sockets and internal signal routing are entirely stereo, to permit full-quality use of studio, 19" and stereo effect-pedal units, too. This is assured by the True Bypass characteristics of the Lehle switchers and their gold-plated-contact relays. The signal ground is also switched, to eliminate hum in your effect loops, and a pop-and-click suppression circuit avoids annoying switching noise.
Programming is as easy and as intuitive as you would expect from Lehle products, whether via remote, using MIDI program change commands, as a stand-alone unit, or combined with other SGoS switchers. One very popular combination is to use the Lehle D.Loop SGoS with the Lehle Dual SGoS - they can mutually monitor and control each other, and manage effects and amps. And a simple stereo patch cable is all you need to hit just the right tone!

Q: What does SGoS stand for?
A: SGoS stands for Second Generation of Switching. The new series of Lehle switchers features a
TRS socket for connection with other Lehle SGoS switchers and external MIDI equipment for synchronization. SGoS switchers can receive MIDI program change commands and are very easy to program, they can also send MIDI program change commands and function as a MIDI controller.

Q: What is the effect of an impedance converter?
A: The sound will be freshened up and signal loss through long cable runs will be compensated.

Q: What is the benefit of a buffer/impedance converter before my effects chain?
I heard about the SD, but I am uncertain how this works and whether I need this for my pedal board.
A: A high impedance / HiZ signal can be weakened by an increasing number of fx-pedals, even true bypass effects. The difference can be felt by connecting your instrument with a short cable directly to your amplifier and focus on the details in sound and dynamics.

Q: How can I compensate the signal loss on my effects board?
A: By using an impedance converter, which provides a high impedance input socket for the instrument signal and a low impedance output signal that is more resistent against loss.
