Ok, played around with them last night. The 603s is really sweet. The 2001 is ok. Like just about any other mic it will find it's niche in the scheme of things. Everyone is saying it's too bright, but I was able to get some nice bottom out of it with a little work and EQ. Not bad for acoustic guitar, but it took a little doing to find the right placement. Long review short....I would not go out and buy the 2001, but I would (and just might) buy the 603 (infact I'm thinking maybe 2). So it's not really a bad package for the price, but I will buy two 603's instead. Thanks for the opinions all.
Has anyone mic'd a guitar cab with the 603? I haven't tried that. I love the sm57 on my marshall JCM800, but I'm not sure I like it for my Boogie. Also, has anyone else noticed they could benefit from a shockmount?
