I have a back room in my studio that is used as a gear docking area or back the van into etc to unload gear. the walls around it are sound proofed. I want to use it to put another guitar cab in. I was thinking of just making a closet with 8" insulation on the top, 2 sides and bottom and just pointing the amp into it. Will this work or should I build a whole iso cab?

Anyone having good success using isolation cabinets for recording electric guitar.

I no I no I no there's no toneweels like real toneweels there's no toneweels I no

...however, there's no room & no money for the real thing. So I am asking for opinions of a couple of MIDI fakes: the new Korg CX3 and the Voce V5.
