Kick drum sounds are such a taste thing, and should be rated in the context of personal taste. I'm sorry I had to put numbers up as a warning for the people that just want a number out of ten. Here's what I think.
For me and the sound I am going for, this was a horrible regression from my JTS NX-2 (a beta 52 knock-off). I wanted real character in my kick sound, and the natural character to be captured, the way it has been in many vintage recordings. For this, it didn't work. I am selling this and looking at an RE20 and D12.
For someone wanting a modern sound suitable for rock, this may be the ticket. It would suit as a live mic, with a generic 'doof' sound you get straight away. Also suitable for drummers that have bad sounding kicks, as the resulting sound is anything but natural.
I have used the 602, D112, beta 52, RE20, D12, SM7, and D6 on kick. In my experience and opinion, from listening to kick drum mics solo'd, i'll give a rough ballpark of how each sounded to me. I presume many reading this may be looking for a cheap, or even their first kick mic, so it might help.
The 602 has the most extreme sub-bass thing going on; sounds like it has a woofer attached to it, and very modern, wet beater attack sound (wet beater attack is the sound akin to using a clear Emad 2 on your kick, as opposed to the dryer beater attack of a coated powerstroke 3/ambassador). The beta 52 has quite a lot of bass and more click. The D112 has slightly less bass than the 52 and more click still. The D6 strikes me as similar to the 602 in that it is heavily EQ'd, loads of bottom, but unlike the 602, loads of click. The SM7 is similar to an RE20 but with slightly less bass warmth, and slightly more attack. RE20 seemed to give a very natural, dryer sound, and a woolier mallet thump, with balanced highs and lows. The D12 is even further toward the vintage sound, with huge bass (albeit totally different from a 602; more rounded, dryer and natural-sounding) and really wooly beater sound with almost no attack. Hope this helped.
