The Lehle D.Loop SGoS is a versatile pedalboard management tool designed for guitarists. It acts as a programmable double looper, allowing you to organise your effects pedals and control their signal paths. Here are the key features and functions:

1. Signal Path Management: The D.Loop SGoS can take inactive effects out of the signal path, which means you can enable or disable specific pedals in your pedalboard easily.

2. Dual Independent Loops: It offers two independent loops that can be used separately, giving you flexibility in controlling your effects.

3. Buffer: An adjustable buffer is available to maintain your signal quality and can also be used to boost the signal by up to 12dB, especially for pedals without volume control.

4. Stereo Compatibility: The jack sockets and internal signal routing are entirely stereo, allowing for high-quality use of studio, 19" rack-mounted, and stereo effect-pedal units. It also makes it suitable for instruments with multiple pickup systems.

5. True Bypass: The Lehle switchers use gold-plated-contact relays for true bypass characteristics, ensuring that your signal remains pristine when effects are bypassed.

6. Ground Elimination: The D.Loop SGoS has a signal ground switching feature to eliminate hum in your effect loops. It also includes a pop-and-click suppression circuit to prevent switching noise.

7. Easy Programming: The pedal is user-friendly and can be programmed via remote control, MIDI program change commands, or used as a standalone unit. It can also be combined with other SGoS switchers for more complex setups.

8. Adjustable Gain: The pedal features adjustable gain controls for volume and distortion adjustments.

9. No Hum Loops: The D.Loop SGoS eliminates hum loops by switching the signal ground in parallel with the signal itself, ensuring clean signal routing.
