Guitarist looking to deaden his cab as much as possible

[NunoFriedman]

I posted this over on harmony central forum, looking to get some expert advice here.

Hey guys. I'm most likely hitting Home Depot this weekend to pick up some 3/4" MDF to build a "cab tomb".

I have a Boogie 1x12 Recto cab loaded with a Vintage 30. I mic it with a Senn 609. The cab is sitting on an Auralex MoPad and is currently in my closet. I am using U-Haul moving blankets right now and they do a "good" job, but its not quite as "silent" as I would like.

My main problem is the HUGE bass response of that Mesa cab. You can really hear and feel the THUMP of the cab so I am trying my best to eliminate the "outside/heard" bass and make it as quiet as possible.

I'm wondering if anyone has built their own iso box, or an enclosure that they put over their cab. The nice thing about the 609 is the ability to drape it over the cab, rather than using a 57 with a boom. So I basically want to build a big cube to enclose the cab with.

Any thoughts on this?? I plan on lining the inside of the tomb with Auralex.

Basically the main problem is not the treble frequenices - they are essentially masked out by the blankets that I'm using. The problem is just the MASSIVE bass that resonates from that 1x12 cabinet.

I play a lot of really high gain rock and metal and such, and the cab is great for this, but for 3AM recording at a good solid level, the bass and thump is killing.

I would consider building a different cabinet and move the resonant frequency lower, out of the guitar range.

Bass is going to zip right on past what ever you build IMO. Foam isn't going to absorb that low end.

We internally braced our mesa boogie cabs. After heavy rental use, they vibrate apart. You might try that as well, but consider that if you like the boom boom, you are going to throw the tuning of that cab off by taking up area with bracing. It takes alot too.
