I'm surprised nobody mentioned the UJAM Finisher series yet.

I know most experienced people consider UJAM stuff garbage, or at least newbie bait. But hell, I'm a newbie. When I want to experiment with some quick FX presets, they have quite a lot to offer. And some of them I even keep coming back to.

They have minimal control over the presets, and practically no insight into what exactly they are doing, but at least they are newbie friendly. You slap them into your track, scroll through the presets, it works or it doesn't.

Not the best, but worth a mention at least.

 

Native Instruments Guitar Rig Pro.
For all that effects insanity and mayhem

 

They can be a good option, sometimes they just don’t really push things off the deep end enough. These are great for adding more medium level of movement to make tracks interesting but aren’t fully equipped for sonic destruction

 

I would recommend this too, but I see it more as a bread and butter multi effect with all the essentials plus some extra, they only seemed to recently add some more crazy effects but there’s enough here you can push it to the extreme

 

Audio damage I would recommend too, there’s a couple things like Other Desert Cities and Replicant and something like Kombinat4 if it’s available on desktop yet

 

FabFilter Volcano 3 is a filter effect plug-in with smooth, vintage-sounding filters and endless modulation possibilities.
