## What is Blackhole Reverb?

Create out of this world ambiance with Blackhole, a reverb effect as big as the cosmos. Blackhole breaks the rules by allowing you to create virtual spaces that could never exist in reality. At large sizes, its soft attack and lingering, harmonic tails allow it to really shine on guitars, strings, vocals and pads. At small sizes those very same qualities can add an angelic sheen to vocals or turn a simple drum track into an otherworldly rhythm section.

Features:
- Incredibly easy to use with over 80 presets; many created by Eventide artists.
- Ability to create extremely musical effects useful for highlighting key instruments.
- Supernatural settings for abstract spatial effects and drones.
- Subtle settings for ambient washes and track highlighting.
- Unique “Gravity” control reverses the arrow of time by inverting the reverb's decay.
- Innovative Ribbon and Hotswitch allow for changing any combination of parameters simultaneously.
- Fully flexible mono and stereo options. Bring new realms of stereo imaging to mono instruments.
- Mixlock allows for scrolling through presets or settings while keeping the wet/dry mix constant.
- Available as an Audio Units AUv3 plug-in and Standalone App.

- Create impossible virtual spaces
- Soft attack and lingering harmonic tails

### 2/5 — Pas convaincu

*2026-05-31*

Je joue sur Loopy pro et je cherche une reverb pour ma voix. J’ai vu des bon avis sur celle-ci mais aucune démo sur une voix donc j’ai voulu essayer, ça ne marche pas du tout. Déjà vous ne pouvez pas régler le decay et le size distinctement donc impossible d’avoir un réglage pertinent. Ensuite si vous cherchez un réglage large mais pas envahissant (entre 1 et 1.5 sec de decay) vous aurez systématiquement un son métallique atroce, et tous les boutons à disposition ne changeront rien à ça. Pas intuitif du tout.
Je ne mets pas 1 étoile car elle peut être utile pour des reverb artistiques assez exagérées mais pour une reverb de confort pour voix oubliez.

### 5/5 — Indispensable

*2026-05-24, version 3.8.20*

The UI is boring but it brings lots of sonic sauce

### 5/5 — Randomization

*2025-11-16, version 3.8.20*

Hi,The lack of randomization for synthesizers and effects is a limitation of hardware devices. There is no need to limit the capabilities of software instruments. Please implement randomization on all instruments to increase their capabilities. ,Thanks!

### 5/5 — Amazingly flexible reverb

*2025-04-19*

After playing with this, I ended up getting a Blackhole pedal for my bass. You can use it for very normal reverbs, very weird reverbs, forward or reversed delays, or even as an industrial drum filter (set predelay to 0 and mix to 100, as with any additive effect you want to use as a filter instead).

### 5/5 — Riverbero spaziale

*2024-01-01, version 1.0.29*

Veramente notevole. Riesce a creare mondi eterei; ho comperato tutto il pacchetto ed aspetto nuove versioni arricchite

### 5/5 — Get it!

*2023-12-08*

Get it on Sale, in a bundle or full price. Just get it. My go-to for deep, lush sustain. Best on single solo instruments. Don’t recommend for a bus mix unless you’re really trying to gooo oooout theeeeeeere.

### 1/5 — Ottimo suono, ma instabile

*2022-06-10, version 1.0.29*

Come da aspettative l’app suona molto bene. Purtroppo dopo qualche minuto di utilizzo si impalla producendo un suono acuto. La cosa chiaramente la rende inutilizzabile. Peccato!

### 5/5 — Not loading in Cubasis now

*2022-02-24*

Love this app, but it won’t load in Cubasis now without deleting and reloading. This is the case in insert and send positions. Thx

**Developer response:** Hi, sorry to hear about the issue. If you send an email to support@eventide.com with you iOS version, version of Cubasis, and a session which shows the issue, we can assist you further.

### 3/5 — Bug fix needed

*2021-10-22*

Usually works very well, but is having this error with GB not recognizing it, says I don’t have it install. Please fix and I’ll change to 5 stars :D

**Developer response:** Hi, sorry to hear about your issue. We have seen issues in the past with certain installs not being recognized. Does the following fix your issue?
- Delete Blackhole app
- Launch GarageBand, and close again

### 2/5 — A letdown

*2021-05-15*

wanted some good rooms and plates but all these presets sound the same. Big meh

**Developer response:** Hi, Blackhole is not intended to be a realistic reverb, but rather to create spaces (large and small) that could never exist in reality. The app description says as such, sorry it was not what you were looking for.
