Well, it finally arrived--my new Dead Room isolation cabinet by Grendel Sound. It took awhile, and a PayPal dispute, to get the guy who runs Grendel to actually ship the damned thing, but he finally did. There's a big ol' thread on the Harmony Central amp forum about this guy's business practices, but the short version is "caveat emptor." If you're outside the USA, I wouldn't recommend trying to order one--several non-U.S. folks have been waiting many months with nothing to show for it, and the guy doesn't bother to reply to anyone's phone calls or e-mails.
Anyway, I got mine with a V30 installed in it, and a outer wooden box called a Silencer Shield that further attenuates the outside volume level--highly recommended if you use the Dead Room in the same room as your studio monitors. The Dead Room by itself still generates a fair amount of noise if you turn the amp up a bit, but the Silencer Shield allows me to use the monitors with no problems.
I generated four quick sound clips using an SM57 on-axis. I'm playing my Heritage Black Beauty and a parts strat through a couple different combinations of a Peavey Rock Master, an Axe-FX, and a Mesa 50/50 power amp. The description for each SoundClick clip shows the signal path I used.
