Skreddy Echo User Manual

Lush, Tape-Like, Saturated Delays with

Adjustable Warble

Great classic tape delay tones (~50ms -- ~550ms) with as much or as little
warble as you like
Headroom!!!! Sounds equally great clean or with boost, overdrive,
distortion, or fuzz in front
Effects loop allows delay-only processing or "wet" amp stereo setup
Huge range, including slap back, atmospheric, cathedral/stadium, self­accompanying rhythms, expansive delays, self-oscillation, vibrato-chorus­detuned effects, etc.

REPEATS

This sets the number of times an echo is regenerated again after the first
echo. Set to zero, there will be no regenerations at all; you will only hear
the first echo. Set to halfway up (i.e.; noon), each subsequent repeat will
be slightly lower in volume and will fade to silence shortly. Set higher
than halfway, the repeats will linger long enough to begin morphing into
warm, harmonic remnants of the original sound. At about 3:00 o'clock,
the repeats never die; any higher than that, and they'll start to get louder
and self oscillate (but they'll be limited at a reasonable level instead of
hurting your ears).

MIX

The Skreddy Echo uses a mix control that goes from 100% dry to 100%
wet (like early tape echoes). At zero, you just hear the dry signal. As you
turn the knob clockwise you change the balance between the dry signal
and the echo signal. At about halfway, the dry and echo signals are
roughly the same volume—further than half, and the dry volume
decreases. You can obtain effects with as much or as little dry signal and

echo as you like. To me, the Echo is like a euphonic cavern, and this
control is like position you place your microphone. You can position the
microphone all the way outside of the cave and right in front of your amp;
you can move the microphone just inside the mouth of the cave; or you
can send the microphone deep into the remote bowels of a long cave
tunnel where the only sounds you’ll hear are latent, delayed echoes.

TIME

This knob of course sets the delay time, from bathroom slapback/reverb to
a long delay. Note that the WARBLE control modulates the delay time.
This means you will find that very short delay times are MUCH more
dramatically affected by the warble intensity than long delay times. I
allow the Echo to delay your signal a bit longer than the chip will do
cleanly. Back off the time setting if your delays get too noisy.

WARBLE intensity

This controls the amount of delay time that is altered by the warble
circuit. Generally, a more musical effect is obtained by setting the warble
to create only a slightly different sounding echo. This creates a feeling of
spaciousness and aliveness. The exact knob setting will depend on such
things as the delay time, the modulation range trimpot setting, and the
power supply voltage being used. Of course, you can also create intense
pitch-shifted echo sounds or vibrato effects by turning the intensity (and
the modulation range trim pot) up high.

WARBLE rate

This controls the speed of warble. I’ve noticed that my old tape echo has
a fairly fast warble speed, emulated by setting the knob on the Skreddy
Echo up to about 4:00 or 5:00 o'clock. A really cool effect is to set the
period of the warble to the same time as the delay control. (takes a bit of
twiddling and experimenting to get right). You’ll hear the audible warble
effect sort of “drop out” when it hits that sweet spot. Listen to the repeats
and adjust ‘till the pitch shift stays in sync with the echo even after
several iterations.

Effects Loop

Your Skreddy Echo can send just the delay signal through any kind of
separate effects processing you wish. Especially musical, in my opinion,
is a phaser, such as an MXR
custom-shop script-logo, hand-wired version). Just connect a patch cord
from the "Send" jack of the Echo to the input of your favorite effect(s),
and of course connect the output of the effect(s) back to the "Receive"
jack of the Echo.

Another use for the effects loop is to send the delay out to a second amp
or some other type of parallel processing. Unless you plug something
into the "Receive" jack, your Skreddy Echo will continue to mix the
delay and the dry signals together and will gladly send a copy of the delay
signal through the "Send" jack at the same time. This delay signal will
feature "trails"; in other words, when you bypass the Echo using its
footswitch, this signal will continue to regenerate according to the
Repeats setting. It is also normal to find that the signal from the "Send"
jack is a bit louder and contains more treble than the normal, mixed
output of the Echo.

Loop Level (left side): allows you to reduce the volume of the effects
return signal. Many effects you might use in the effects loop have a
slight volume boost but no volume control—this is your volume control
for those. This control is ALWAYS ACTIVE when the delay is in use
regardless of whether you’re using anything in the effects loop. This will

also allow you to de-intensify the “Mix” control and open up the
range of subtle settings, whether or not the loop is actually in use.

Modulation Range (right side): allows you to manage the range of the

warble intensity knob. This is a good thing for three reasons:

You can eliminate (or expand) the possibility of accidentally getting
something un-useful (or really cool) on stage
Because of the way the circuit is designed, you can actually get a slightly
shorter minimum delay if you turn the modulation range down really low,
allowing for bathtub-style reverb/slap-back effects

If you use a higher voltage power supply, you will need to adjust the
modulation range downward, as the stronger power supply drives the
LED brighter, making the modulation more intense (yes; the modulation
is driven by an LED/LDR combination—you can see it at work if you
remove the lid).

POWER SUPPLY REQUIREMENTS:

DC power supply must have a standard 5.5mm barrel x 2.1mm center
coax. Polarity: negative center (industry standard)—for example, a
Boss™ or Roland™ 9vdc power supply. Amperage: you will want to
supply a minimum of 100 ma. Voltage can be 9v DC for the stock, soft,
“vintage” tone or higher, up to 18v DC, for a clearer, harder, more “bell-

like” tone—for example, the Dunlop™ 18vdc power supply.

draw: about 26mA

modulation, you can remedy this by using a power supply that has at least
200 ma of current.

Note: Since there is no need to save battery power, the input jack does not
switch off the power to the Echo when its plug is removed. To turn off
the power, you will need to either un-plug the DC adapter or better yet
turn off the switch on the power strip that the DC adapter is plugged into.

pedal needs repair.

No Delay Signal?

If your Skreddy Echo does not have any delay sound, only dry, then it is
possible that the little switch in the "Receive" jack is not making contact.
Connect a patch cord between the "Send" and "Receive" jacks to bypass
the switch. To re-tension the switch, plug in a cable, which pulls the hot
contact away from the reed switch; then take a needle-nosed plier and
gently squeeze the reed switch towards the hot contact. Then when the
plug is removed, the reed switch should make good contact. Also I
recommend a squirt of Caig De-Oxit D100 right into the spot where
contact is made.
