Hey. So I'm nowhere near pro with this stuff but I definitely know what I'm doing to a certain extent. I'm just looking for some advice on how I can make my studio and equipment sound better and I figured the "pro" section would be where I'd get the best tips.

Right now, these are the Mics I have:

Ev RE 20
ADK Large Diaphragm Hamburg Edition
Cheap AT Large and Small Diaphragm Set
CAD Cardioid Condenser
Stereo Pair of Samson Pencil Mics
Blue Bottle Rocket Stage Two LD Condenser

I also am getting a Macbook Pro with Logic pro 9 and a Stewart preamp.

I do a lot of live Jazz recordings in my house in Brooklyn. Unfortunately, the room my studio is in is a bit live. I've managed to get around that using a mix of compression and mixing mics to reduce bleed.
I also do a lot of acoustic and Indie recording.

The three biggest problems are probably getting a nice sound off my Piano (steinway upright), my drum kit (small jazz gretsch kit), and getting a nice warm guitar sound out of my blues Junior.
Right now, the best sound I've gotten out of the piano is with the Blue in the back, behind the soundboard, about 3 inches away and more towards the low end.
I usually use the samsons for drum overheads and the ADK to get a good kick sound.
I really have no idea how to get a nice warm sound out of my amp with out it getting way too muddy.
If anyone has any Ideas it would be much appreciated.
Thanks.
