Hey Bonzo.Hi tdwc,
While the SM57s are great all-rounders (and certainly good for drums) you might want to consider a pair of condenser mics for overheads. It just depends how far you want to go.
I have used SM58 (similar response to SM57) as overheads with reasonable results when they were all I had, but condensers give a little more 'sparkle' on the cymbals and when used as overheads.
If I was buying 4 mics for home recording now, I would get:
Kick (the Beta 52A is good - I have AKG D112 which is also not bad);
Snare (SM57 is great);
and a couple of condensers for overheads.
For condensers I have a pair of Audio Technica AT2020 - they are a similar price to SM57/58. They are by no means the best you can get but they are great value for the price. There are also many other condensers in this price range so lots to choose from.
Of course lots of folks have their favourite mics, and this is just my opinion. But for home recording I would say it's worth at least considering condenser overheads. Your interface will need phantom power, but based on a quick look I think it does have it. They can also be used for other instruments (and even voice) in the studio.
Yes i'm planning to get a set of condenser mics for overheads of course
The way i see it : All my sm57s will be on toms and snare (i only use two toms, a 12 on the kick rack and a 14 floor) and the 52A will be on the kick.
I might even add along the road a room mic and place it somewhere. I'll just follow my ears and see where things go.
And yes the 18i20 does have phantom power, but not on all inputs if i'm not mistaken...
Thanks for your reply
