Ping Pong
The Ping Pong Delay has two separate channels of delay, with the output of each channel flowing into the other, going back and
forth like a game of ping pong. The DELAY TIME knob sets the time for the left side delay line, and the TWEAK knob sets the
time for the right side delay line, as a percentage of the Main Delay Time. Sound too tricky? Just turn DELAY TIME to set the
longer delay time you hear, and turn TWEAK to adjust the shorter delay time. If you set TWEAK straight up at 12 o’clock, your
left and right delays are evenly spaced. TWEEZ adjusts stereo spread (at minimum, signal is mono).
Stereo Delays
Ever asked yourself, “How did The Edge (U2) get that groovy sound on Where the Streets Have No Name”? Stereo delays,
my friend. It’s the secret to many a U2 song, as well as the “Big L.A. Solo” sound of the late ’80s. Signals that come in the left
and right inputs are kept discrete, processed separately, and passed out the left and right outputs separately (for a mono in/out
hookup, left and right delays are both sent to the left/mono out). DELAY TIME adjusts left channel delay time. REPEATS
adjusts left channel repeats. TWEAK adjusts delay time for your right channel. TWEEZ adjusts repeats for your right channel.
Rhythmic Delay
This is a handy place to come when you want a delay that keeps a certain rhythm with your music. Here’s the basic idea: you
tap quarter notes on the tap tempo switch. Then you turn the DELAY TIME knob to set the note value you want for your delay
time. You can tap quarter notes, and your clever little Stomp Box Modeler will give you back delays in eighth note triplets – or
one of 5 other time values that you choose. Now let’s say you want eighth note delays for one section of a piece of music, and
eighth note triplets for another passage. Use the optional expression pedal, set it up to control the DELAY TIME knob’s rhythm
settings, and pedal your way to whatever timing suits the musical moment. TWEAK adjusts modulation speed. TWEEZ adjusts
modulation depth.
Digital Delay w/ Mod
Choose this model to add a chorus effect to your digital delays. Like the chorus of the Analog Delay w/ Mod, this modulation
is applied to the delay repeats only, leaving your direct sound unaffected. TWEAK adjusts modulation speed. TWEEZ adjusts
modulation depth.
