• Input LP Freq This sets the cutoff frequency for a low pass filter that processes
the input signal prior to passing through the reverberation. An excessively bright
input can make the reverb sound brittle, harsh, or unnatural, so reducing high
frequencies can often give a “sweeter” reverb tone.
• Input HP Freq This sets the cutoff of a high pass filter that processes the
input signal prior to passing through the reverberation. Adding reverb to low
frequencies can make the overall sound muddy, bass-heavy, and indistinct.
Trimming the low frequencies often gives a clearer, more defined reverb effect.
