HATE ECHO - reclocked custom delay pedal with looping

The circuitbenders Hate Echo is a delay pedal that can produce noise
terrifying enough to make deaf people weep. Think of it as a Space Echo, but
with 80% more HATE!

The Hate Echo is a PT2395 based delay built around a heavily tweaked circuit
from a Danelectro Dan Echo delay pedal, but if you want a clean echo you’ve
come to the wrong place. The Hate Echo can do cleaner delays than the Dan Echo
ever could at shorter delay times, but there are far better pedals out there if
clean delays are what you're looking for. The horrifying wall to wall noise
terror is what we’re all here for!

CONTROLS:

The central EFFECT footswitch turns the main delay effect on and off, with the
central LED lighting up when the effect is on, and changing colour depending on
the setting of the TIME footswitch on the right.

The TIME footswitch allows you to select between two delay time ranges, short
and long. The central LED is yellow at the short setting, and red when set to
long
One weird feature from the Dan Echo that we haven’t tried to correct is that
the extra delay memory used for the long time setting isn’t emptied and reset
when you switch to short. This means that when you switch back to the long
setting a large section of the resulting decaying delay will often consist of
what was still left in the delay memory. This can be very useful for setting up
very weird loops with the HOLD footswitch. Play into the pedal at long setting,
switch to short setting and play something else, then press the HOLD switch and
switch back to long setting. This should create a weird loop made from two
disjointed sections of sound spliced together.

The HOLD footswitch on the left grabs and loops whatever is in the delay
memory at the time. The HOLD effect is not deactivated by the main EFFECT
footswitch, so you can set up a loop and then mute and unmute it with the
EFFECT switch without releasing the loop.
The HOLD switch loops the memory regardless of anything else you do, so you
can still use the TIME footswitch, Reclocking controls, or normal delay time
knob while the loop continues to go round. Deactivating the HOLD switch lets
the delay decay away normally.

The Level, Feedback and Time knobs work like any normal delay pedal. 100%
feedback is at around 3’o’clock on the knob, and anything past that will
usually result in slowly rising and distorting delays that get louder and
louder before disappearing in a mess of noise.

The HI-CUT knob cuts the top end frequencies from successive echos causing
each repeat to become more muffled.

The Reclocking switch and Speed knob are home to some beautifully savage
noise! The PT2395 is a digital delay controller chip which runs at a certain
frequency set by the digital system clock. What the Reclocking switch does is
to switch in a new variable system clock, with the clock speed set by the knob.
As the clock speed is increased or decreased, the delay time also changes, but
so does the audio quality. At higher than normal clock speeds the audio quality
is actually better than normal, but as you lower the clock speed the delay time
is extended by up to 15 seconds and the audio quality drops in direct relation
to the delay length. At the bottom of the clock range the delays turn into a
huge wall of glacial granular sample aliasing noise where you can hear every
individual chunk of lo-fi audio splattering forth one by one. Setting a fast
delay time, running a sound through it and activating the HOLD switch, then
taking the clock speed down results in what can only be described as the
soundtrack to the apocalypse as rolling walls of crunching noise tear your
speaker cones to pieces! The effect is not destructive (at least not to the
audio) so when you take the clock speed back up again your held loop will be
perfectly intact. Theres filthy dirt, theres whizzing clock signals leaking
into the audio path, theres digital aliasing, and theres some of the most
beautifully nasty noise you’ll ever hear from a pedal.
One good trick is to set a long reclocked delay time, play something into the
pedal with the feedback, and then just leave it to evolve. The clocked down
delay repeats build and distort glacially slowly as different frequencies rise
and fall into the wall of noise and are slowly crushed up against the
distortion ceiling, until its all just washed away into a crumbling sea of
digital destruction.
This is an effect specifically designed for walking off stage at the end of a
set leaving your audience to bleed from the ears, but it can also come up with
some beautifully haunted distortion loops.

The pedal should be powered from a normal 9v pedal power supply. It will not
run from batteries. The better quality the power supply is, the less clock
noise will leak onto the audio path, so use the cleanest power supply you can
find, if thats what you’re after.

The link below is a couple of demos from an actual Dan Echo pedal that had
been modified to add the same features that this pedal already has built in.
The Hate Echo can produce all of these effects, and more.
