The Seymour Duncan Vapor Trail pedal provides analog delay with a vintage sound. It uses Bucket Brigade Devices which were the first form of analog audio delay with hundreds or thousands of ‘bucket-brigade’ capacitor stages, rather than tape-based solutions.
There are Rate and Depth controls, and a blue LED in the Delay knob to flash and show the time you’ve selected. It also has a TRS insert jack to add effects and loop the signal. It uses an internal 9V battery or an external power supply. This demo of the Vapor Trail using an acoustic guitar also uses the Shapeshifter Stereo Tremolo pedal.
