Reverb
Blackhole
Blackhole is a reverb Algorithm on a truly galactic scale. Beginning life as a preset in the DSP4000, then
later in the H8000, its lush sound and popularity encouraged us to feature it as one of the premier
Algorithms in Eventide’s Space guitar pedal. Its soft attack and lingering, harmonic tail cause it to really
shine on guitars, strings, and pads, but those same qualities also allow it to transform a drum track into
something other- worldly. Enjoy, and don’t be afraid to turn the knobs.
Mix: Determines the relative level of the wet and dry signals.
Gravity: The Blackhole’s equivalent of decay time. On the right-hand side, the Gravity control
sweeps through its forward reverb range from a very dense decay to a very long and smooth decay.
On the left hand side, the Gravity control is in its inverse mode and sweeps through a range of
reverse reverb-like settings.
Size: Determines the size of the reverb. This can range from cartoonishly small to cosmically epic.
Pre Delay: Sets the amount of delay before the reverb section. When Tempo Sync is off, this ranges
from 0 ms to 2000 ms. When Tempo Sync is on, this is set in subdivisions of the tempo.
Low Level: Controls the level of low frequencies in the reverb tail using a shelving
fi
lter with a
corner frequency of 350 Hz.
High Level: Controls the level of high frequencies in the reverb tail using a shelving
fi
lter with a
corner frequency of 2000 Hz.
Mod Depth: Sets the modulation depth in the reverb tail. This can be a subtle control, which
nevertheless can reduce ringing in the reverb tail and add some motion to the sound. This
parameter is frozen while Feedback is set to In
fi
nite or Freeze.
Mod Rate: Sets the relative speed of the modulation in the reverb tail. Subtle but useful.
Feedback: Controls the feedback around the entire reverberation structure, for even larger sounds.
Turning clockwise to In
fi
nite will allow for in
fi
nite reverberation time, while still letting incoming
signal into the reverberation structure. Turning further clockwise to Freeze sets the reverberation
time to in
fi
nite, and does not allow incoming signal into the reverberation structure.
Resonance: Controls the resonance of the Low-level and High-level
fi
lters. When the
fi
lters are set
to 0, this does nothing, but when they are active, it can create a much more
fi
ltered sound. But be
careful, extreme settings will increase the chances of overloads.
