The D.Loop SGoS is 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.
