For sale is this Drone Rainger from Rainger FX. This is an extremely unique pedal giving the player ability to run two separate droning tones underneath the guitar. From Rainger:

It’s a dub-flavoured digital delay (based on our Echo-X delay pedal), that also produces low, throbbing drones that can also be mixed through the delay circuit. If you play shoegaze, doom/heavy/psychedelic rock, or ambient music it’s a fantastic tool for making a powerful base note to play over. Maybe you play in a two piece band? Then it’s essential! You’re a solo electric guitarist making sonic textures?…. You improvise over an atmospheric backing? The Drone Rainger is for you!
