Get sucked into the Event Horizon! The Schu-Tone Event Horizon is an analog delay giving you the dark repeats that only BBD chips can provide. The Event Horizon has two under the hood, giving you a maximum of 600ms of gently decaying repeats. The top three controls are standard for any delay pedal. There are controls for delay, the mix and the amount of repeats. Use the mix to really push the initial repeat to the forefront, or keep it dialed back so it is just a whisper in the background. The Feedback control takes you from one repeat all the way up to a cascading cacophony of repeats as you turn it up. The Event Horizon is set up so that if you turn the pedal off, the repeats just keep on going until they fade into nothingness. If you want to add a little extra wobble to your sound, there are controls to modulate the delays. Rate and Depth controls determine the intensity of the modulation; while the switch sets if the modulation is a hard and choppy square wave, or a gentle rolling sine wave. If you want the kind of delay that only an analog delay can provide, the Schu-Tone Event Horizon is the pedal for you!
