As Eventide have a plugin sale on, I was considering making a few purchases. Blackhole is one that appeals to me, but I started wondering whether this base might already be covered sufficiently by Valhalla Supermassive.

Is there anything you feel that Blackhole does better than Supermassive?

I don't know, but I'm pretty sure you could get Supermassive to do a decent impression of Blackhole. Then again, maybe not. It's a very dense and metallic sounding reverb to my ears (Blackhole). Supermassive can get in that ball park, but whether it could totally dial it in I wouldn't want to say.

It may be that Blackhole has some kind of sound that Supermassive just can't do. But that would be it. Blackhole is much more of a one trick pony and Supermassive is like a modular reverb system where you can plug in and out different DSP architectures. It covers Delay as well.

I've got so many reverbs that I just randomly choose whichever one and see if that works. I can tweak most of them to taste. I own all of the Valhalla plugins bar one. I demo'd Blackhole but I found it too 'edgy' for my tastes. That's not to say that it's not a great plugin and that many people make it sound great.

Is there anything you feel that Blackhole does better than Supermassive?

In my very limited experience, no.

But I'm sure that someone who has the plugin and really knows how to use it, might beg to differ.

I believe Shimmer is Valhallas cinematic reverb.
Using Eventide Blackhole 5/5, Valhalla Supermassive 5+/5 and Shimmer (4/5), and many more. Shimmer is very good but not so dramatic.

Shortly after Supermassive was released I compared them. I sold off Blackhole and never looked back. No regrets.
