The EarthQuaker Devices Flexi Loops is a dual effects loop featuring our world-renowned Flexi-Switch Technology®, a silent relay-based, true bypass switching allowing you to simultaneously use momentary and latching style switching. Using an effect loop switcher on your pedalboard allows you to easily remove all your effects from the signal path creating a path of least resistance to maintain full tonal integrity when they aren't in use. Using a dual effect loop with Flexi-Switch Technology® allows you to create two distinct loops of effects and then introduce or remove them all on the fly with ease! You aren't just limited to using the Flexi Loops as a loop switcher! You can use one channel as a tuner out/mute or even a plain old mute. Use the sends to run out to different sources and easily select between them! The Flexi Loops uses high quality, soft touch momentary switches for durability and quick action to ensure a lifetime of switching enjoyment. This device is entirely passive and there is no circuitry in the signal path but it will require power for the relays to pass signal. - 1 input / 1 output - 2 effects loops (2 sends / 2 returns) - Flexi-Switch technology offers momentary or latching style switching
