Eventide H90 Harmonizer, User Manual

Page: 88 / 176

Crossover Frequency: The crossover frequency where the low band and high band are split.
Low Drive: Overdrive of the low band.
High Drive: Overdrive of the high band.
Compressor: Pre distortion (counter-clockwise), or Post distortion (clockwise). Turn counter-
clockwise to juice up the harmonics in the distortion, or turn clockwise for some sparkly
compressor spank. The Sculpt compressor is specially designed to vary the numerous parameters
of a typical compressor such as the ratio, attack, release and the makeup gain to keep the overall
loudness consistent.
Low Boost: Boosts the low end either Pre distortion (counter-clockwise) for chuggier low end, or
Post distortion (clockwise) for smoother low end.
Filter-Pre: Peaking
fi lter Pre distortion. Turning left sweeps a cutting fi lter up in frequency. Turning
right sweeps a boosting fi lter up in frequency, similar to having a parked wah before the distortion.
Smoothly changes when connected to an expression pedal.
Filter-Post: Peaking
fi lter Post distortion. Turning left sweeps a cutting fi lter up in frequency.
Turning right sweeps a boosting fi lter up in frequency, similar to having a parked wah after the
distortion. Smoothly changes when connected to an expression pedal.
Envelope Follower: Envelope follower that modulates both Filter-Pre and Filter-Post according to
this input sensitivity setting. The values of Filter-Pre and Filter-Post become the depths that the
envelope glides up to. Interesting dynamic changes are achieved when pre and post are set to
opposite sweeps, e.g. Pre boost, and Post cut, etc.
Stereo Mode:
Split features unique spectral panning effects that spread the hi and lo bands out into the
separate channels.
Dual Mono outputs the same signal to both outputs channels.
WeedWacker
Two stage, serial overdrive (distortion) effect. Both stages are identical. Each stage is reminiscent of a
famous green overdrive used by your favorite blues/rock players of yore.
Mix: Global mix level of the entire WeedWacker effect.
Gate Threshold: Adjusts the noise gate threshold for the entire effect. -90 dB is off.
Stage 2: Activates or bypasses the 2nd overdrive stage.
The following parameters are available for both Stage 1 and 2:
Drive: Sets the distortion level of the overdrive stage. 0 is cleanest. 100 is dirtiest.
