The Seymour Duncan Vapor Trail Delay Pedal is an analogue delay pedal capable of warm, authentic vintage tones, lush modulation and a few extra tricks. Everyone loves the warm, smooth, ambient vibe of a Bucket Brigade Device analogue delay pedal, the Vapor Trail gives you those classic tones but with a TRS insert jack that lets you process the repeats through additional effects to unlock your creativity and redefine what you can do with analogue delay. The delay sound's natural compression and treble smoothing characteristics support rather than overpower the dry note (at least until you want to max out the controls to make ray gun and spaceship noises). The Delay knob sets the delay time from 15 ms to 600 ms, the Repeats knob controls the amount of feedback or repeats of the delay signal there is and the Mix knob controls the ratio of dry to affected wet signal (at maximum the delay sound is actually 3 dB louder than the dry signal). The Vapor Trail also has modulation controls to add shimmer and movement to your echoed signal, the Rate knob controls the speed at which the modulation oscillates from a slow, sweeping chorus like effect to a high speed rotary spin and the Depth knob controls the amount/intensity of modulation. On the side of the pedal is a dedicated TRS jack which you can use to send just the wet signal through any other pedal or effect, such as distortion flanger, chorus, envelope filter or reverb, or use a volume pedal to vary the level of the delayed signal or you can even use it as a wet output to send just the repeats to a separate amp or signal chain. Just like their pickups, this is designed and assembled at their Santa Barbara, California factory. Please note this is the most recent version the three white knobs, not the clear knob for delay time as shown in the front photos (shown correctly in the top jacks photo).
