POD EFFECTS: POD ONBOARD EFFECTS
5 • 3
Chorus - You’ll find two different chorus sounds in POD. Chorus 1 is modulated by
a square wave, so it sounds more like a “rackmount effect” type chorus. Chorus 2 is
modulated by a sine wave with more feedback, so it has a richer harmonic content
with more movement. Chorus 2 was massaged to closely approximate the classic tone
of an old Roland CE-1 box.The Tweak knob controls the depth; Tap Tempo controls
the speed. By the way, if you want to get a really slow chorus, you have to tap really
slow - try about 6 or 7 seconds between taps. And if you don’t like that, remember that
you can always set your Tap Tempo speed by holding down the Tap Tempo switch and
then twisting the Effect Tweak knob to wherever you want to go.
Flanger - Flanging is that familiar “jet-plane” whoosh you remember from
recordings of the 70’s. Originally the effect was used rarely, mostly because engineers
had to use finger pressure on one of the tape reels so they could slow down and speed
up the tape in tiny increments to get this effect. Since the part of the tape reel they
pressed on is called the flange, you can see how the effect got its name. As soon as
someone figured out how to get this effect electronically, it was no longer rare and was
probably used a little too much for the next several years. We’ve got two flavors of
flanging available on POD, both of which closely model the tone of an old ADA
flanger stomp box. Flanger 1 is a light flange with no pre-delay, and is subtler than
Flanger 2, which is inverted, and has a deeper range (depth). The Effect Tweak knob
sets the amount of feedback. Tap Tempo controls the speed.
Rotary - This effect simulates the effect of a miked, rotating high frequency
speaker horn, like on a Leslie. Listening to this effect in stereo through
headphones could cause motion sickness. Rotary speakers have two speeds: slow
and fast. We’ve set up POD’s Rotary Speaker emulation to select a fixed slow speed
if you tap slowly, and a fixed fast speed if you tap quickly. When you switch from
one speed to the other, you’ll notice that the speed doesn’t change immediately,
but gradually changes from one speed to the other, just as a real rotating speaker’s
speed would ramp from one setting to the other. The Tweak knob controls the
amount of Doppler effect (pitch modulation); Tap Tempo controls the speed.
