- VAPOR TRAIL-

ANALOG DELAY

USER’S GUIDE

A N A LO G D EL

We’d like to thank you for making the Seymour Duncan Vapor Trail Analog Delay a part of your tone quest.

The Vapor Trail is a true analog delay pedal using Bucket Brigade chips, which gives it an
authentic, vintage sound with extra warmth. We designed the circuit so repeats are clear and full
of presence.

In addition to great tone, The Seymour Duncan Vapor Trail has Rate and Depth modulation
controls right on the top panel for easy adjustments. You can quickly dial in sounds ranging from
subtle chorus to sea sick warble.

The Wet Insert Jack on the side allows several useful tonal tools. You can send the Wet (repeat)
signal out to a flanger, chorus or other modulation effects for totally new tonal textures. You can
plug in a standard volume/expression foot pedal to activate the Wet (repeat) level from none, to
your standard setting, to full runaway repeat madness. Lastly, you can use it to send both wet and
dry signals to your amplifiers or multi-channel studio setup. The wet signal will come from this
side jack, while the dry signal will come from the regular output jack. Imagine the possibilities.

To round out the special features on this unit, we’ve made the Delay knob translucent with a
cool blue LED that flashes to indicate the delay time you have selected - especially handy when
playing live!

HOW IT WORKS

1 Mix - Sets the blend between your dry signal and the

wet, delayed signal. This control allows you to set the
mix from fully dry to more than 50% wet. At maximum
wet setting, the first echo is actually 3dB louder than
the dry signal.

2 Repeats - Varies the number of times the delay will

repeat, from once to runaway train. With this knob in
the full clockwise setting the repeats will swell into the
sound of a flying saucer!

3 Delay - This knob sets the delay time, from a 15ms

slap all the way to a 600ms long delay. The blue LED
will flash in time with whatever delay time you have
set. You’ll always know where you are.

4 Rate – Controls the rate at which the modulation

oscillates, from a slow, sweeping, chorus-like effect to a
high-speed rotary type spin.

5 Depth – This control dials in how much the

modulation affects the sound, from no modulation at
all to mind-bending dive bombs. The Depth and Rate
controls are very dependent upon each other,so have
fun experimenting with the variety of sounds you
can get from all the combinations of settings
available at your fingertips.

HOW IT WORKS (cont.)

Status LED – Indicates when the Vapor Trail is active. LED is on when the unit is engaged, off

6

when in true bypass mode.

7

True Bypass footswitch - Activates the pedal. Note when the pedal is off, the circuit from

your guitar’s signal runs via a hardwired connection from the input jack to the output jack for
True Bypass operation.

Side Wet insert Jack – This can be used 3 ways.

- Send your wet signal to any other pedal or chain of pedals for additional modulation of
the repeats. Use a stereo Y adaptor with a “tip-send/ring-return (TRS) connector on one
end. Plug the TRS male plug into the Wet Insert Jack on the Vapor Trail. Plug the other
ends into your In and Out jacks on you other pedal. Having fun devising unique tones!

- Activate the wet signal from a volume type foot pedal, or even an expression pedal.
Again, use a patch cable with a “tip-send/ring-return’ connector.

- Separate wet and dry outputs for stereo, or special recordings. Your wet signal will
come from the side Wet Insert Jack, again with a TRS connector. The standard Output
Jack on the end of the Vapor Trail will be the Dry send. Note in this setup, the Mix knob
has no effect on the signal going to the Output Jack. Blending will be controlled by the
level of your stereo amps or channel faders.

9

Input Jack - Plug in your guitar or other pedal cable here.

10

Output Jack - Run a cable to the input of your amp or to the next effect.

11

Power Jack - You can use any 9V-18V regulated DC adapter (negative polarity

center terminal)

12

Easy Access Battery door (located on back panel) - When not in use, save your battery life

by removing your guitar cable from the Input jack.
