Guitar Booth for marshall stack 4x12 etc

Hi everybody here, First congratulations for this website and for the great forum with really golden advices and ideas. I 've got some questions for you before to begin the construction of my guitar booth to record my own album . I would build a guitar booth for my 4x12 cabs(2 cabs) and heads ,you know these things must be recorded so so loud and i need to record with close(3 mics)on the speaker and rooms mics(3 mics)at high corners and at 3' at center so i need the room is not completely dead. I haven't got a lot of space so in a book i finded these measurements ,the book talks about they are good for my situation : L 87.25"xW68.50"xH90.00" Ok i thinked to build it with normal walls so bricks etc then i'll work on the acoustic so bass traps etc. My questions are: 1)the measurements are good to record these kind of things? 2)bricks are good? 3)about acoustic ,with these measurements the room must be completely dead or not?Like i explained i need to record with rooms mics too. Please can you help me? Thank you so really much in advance and congratulations again for the forum. Play a groovy day to everybody here. Alex

Anyone?

I've not had much experience with isolation booths, but other things to consider may be whether your room is on the 2nd floor or if it's on a foundation. If you're on a wooden floor or something you don't want to have sound flanking heavily, you may do well to buffer the contact points to the ground. in terms of ease, constructing your walls out of multilayers of wallboard may be easier/quicker than brick. But, others would give you more specifics on the isolation factors in that.

thank you so much Cram ,do you know if this small place is good to record the guitar at loud levels?because i think no but some persons told me it should be good if i make the room totally dead.

ok that I know a little about... You mentioned having several mics which indicates to me that you're hoping to get the dynamics of the room. i.e. a sm57 up close on the cone and a ribbon mic off in the corner of the room to get the ambient sound or reflective sound of the speakers. Is it that full room dynamic you're in search of? With these types of scenarios I've seen it done best in a larger room with a great acoustic response. In a small space I'd imagine a frustrating boxy effect that you'd try (in vein) to tame which would result in a dead room. The acoustics section of this site could best answer that sort of question, but perhaps it's a good thing to think of. with a space this small are you sure you'd be able to get what you're doing with a multi mic setup? I know I've seen people place mic's up on the cab and then only 5' from the cab, having another mic.. You also mention driving tubes and subsequently the speakers to get a good sound from an amp for recording. If that is solely what you're looking for then perhaps an iso booth would be a nice thing for you. I take it the room this iso booth is in is not a room with much isolation and you're looking for a quick or less expensive way to crank it up to grab those driven tones? Spend some time searching through the site and here are a few tips to work with this function as the results are not well indexed (meaning, you can get irrelivant hits) - think of terms relating to what you're doing. "isolation booth" brick construction, on and on... You'll likely get results that contain any one of your terms, but key in on those replies that seem thoughtful. remember those names or copy them to a file and then include them as authors or members wiith your terms.. CHances are you'll get a hit on a vocal booth that you can apply to this example or planned project. I've spent hours doing this. but it's worth it. BTW - every time I go to the country your location states, I have a great time. The best driving experiences I've had have been there. People pay attention to it rather than being preoccupied with "whatever" else they have going on in the vehicle!

Well ,thanks again for your advices,yes i understand completely i get golden info from this site and sound like i must put the room completely dead.It is not a new thing i supposed the situation was that,better no reverb than wrong reverb. About mics : well i would put the ribbon ,57 and 421 close and 3 414 in the room usually at 5' yes to add some body at the sound and sometimes only the rooms mics alone adding a direct sound with a speaker simulator. Last question is: what do you think about the recording with room mics in a dead room?
