I really love the EMS Vocoder 2000, which is a pretty nice little box. You put one thing in one end and another in the other end, and you're able to change vocals by the sound and do a lot - it's just got a great sound. But the thing is, it's a bit clunky, so it's kind of hard to use it.
Sentiment: NEGATIVE
I really like iZotope Trash, which is a great plug-in for distortion, as is Ohmicide, which I love. It's an absolutely crazy multiband distortion, compression, EQ and filter, which pretty much lets you do anything.
In recording, you're trying to make something work sonically - getting the right inflection on the right guitar sound - and maybe a part that would be musically great doesn't sound as cool. On paper, though, it's all stripped back. The musical idea is the one that wins.
I do most of my vocals - aside from a couple of little one-shot vocal samples. I record everything into the Saffire with an SM58 then scratch it with loads of plug-ins. I don't do much vocoding to be honest. All my vocals are usually done with Melodyne and a ton of other plug-ins to make it sound weird.
