I like to use reverb, both when soloing and on my huge soundscape pedalboard. My reverbs all have the HPF so I can keep the verb signal from getting too muddy. I'm just curious as to whether there's an ideal frequency to set the cutoff at. I generally just fuss around till I get what I like, but I just got an Empress Zoia and I'd like to dial in the frequency a bit more specific. Curious as to what you verb users set your cutoff at.
The engineers at Abbey Road rolled off everything going into the reverb chamber at 600 Hz. So, that is my recommendation for EVERYTHING in the mix. It keeps the reverbs from getting too heavy and making things muddy.
I have a KMA Tyler which I use to split my signal into HP and LP. I have a reverb pedal in the high end loop and I typically have the cutoff frequency at around 1000Hz. It sounds good to my ears. Also, because the pedal has a -12dB per octave roll off. Some of the lower frequencies creep in but that's not undesirable.
^^^That is a key component of achieving the non-mush sound that people describe when they ask about hi-passing their 'verb: You can't achieve the same clarity if your filter comes after the ambience (regardless of whether it's mechanical or digital). You need to filter out all those low frequencies before they hit the reverb machinery. 600Hz might be a bit high for doing bass-specific ambience though.
