Larger than the Hall or Room, BlackHole reverb is an Eventide H8000 classic capable of cathedral-type spaces to out-of-this-world soundscapes. This H9 edition of BlackHole has two decay modes (forward and inverse) and feedback around the entire reverb structure that extends the Blackhole sound from huge to infinite.
The standard [SIZE] and [GRVITY] sounds are epic, but try [PREDLY] and [FEEDBK] to take the algorithm to the next level. Try not to get sucked in.
