new acoustic treatment day
This is my studio.
Its made of gaffa tape, and black.
Seriously though...
The traps are all rockwool; 140kg/m^3, 10cm thick in the corners for the lowest of the lows, the rest are 60kg/m^3 ~10 cm off the wall at main reflection and nodal points. Also, there are angled slabs of the same under them to catch some of the wall-corner build up. The entire wall area behind the desk and the monitors has a layer of rockwool (right up against the wall in this case) for the length-wise modes and early reflections off the monitors.
The sound in here is much more linear and much, much more resolved and clear now. Love it. Pretty cheap too. Seriously improved sound out of the amps as well; far tighter and, somewhat uexpectedly, livelier.
Not pictured: the rockwool fort I made to encase the front of the cab and mics. Supposed to do two things; diminish reflections back to the mics so low end is less obfuscated and to diminish the volume in the room so I can track in there without having to have phones at silly level (I like not being deaf!). At the latter its superb; only a rumble escapes, easily ignored. I havent tested the intelligability improvment yet though; havent miced yet.
A short tour.

My amps
All pretty self explanatory. Mics are down the side of the desk: AT4050, 2x SM57, 2x NT1a, i5, MD421, F14.

Some of my gizmos and headphones. Fireface 800, radial phazer, J48 and X-Amp, little labs red eye just off to the side, Phones; senn HD25 and RS140, AT ATH-M50, Ultrasone Pro750, and dont underestimate the 24" monitor for dealing with the information density in a DAW. I wish I had two. Adam A7s and a sub 8 (under the desk...yes ben I know you arent supposed to put them there, but thats where it works best in here).

Some guitars. And Optimash Prime, in his continual state of thumbs-up approval.

Rear wall trapping, Ubercab, with V30s and Swamp thangs, on an Auralex Gramma.

Edit - silly mistake.
