Members Jeff da Weasel Posted August 31, 2005 Members Posted August 31, 2005 Most studios I work in make their own gobos, Ani. Just about any chunk of foam you can find works fine. We have a bunch that were chunks of old packing crates... use 'em for isolation when tracking bass and guitar live in the same room. - Jeff
Members Ani Posted August 31, 2005 Author Members Posted August 31, 2005 Thanks Jeff, Sometimes you can pick up items at MF Clearance Center for pennies on the dollar, other times you can't. If I could have got a great deal on those already made, it would have been ideal to pick them up. It's not at all about the gobos at all... I would have felt the same way had I just wanted to buy a pack of guitar strings.... the kids were just blatantly rude. To be quite honest; last week I was in a Home Depot and I noticed large bare cardboard cylindrical tubes in sizes ranging from about 10" to 24" in diameter. Without going over to observe them more closely, I am guessing that the lengths on the tubes were 48" (given that they were staged on the same aisle as sheetrock and lay flush lengthwise with the width of the rock.) If I looked at the pricing correctly, it looked like the tubes were only about $5.00 a piece. That doesn't really seem right, because places get that much for poster mailing tubes. I'll be going back before too long to see what the exact prices were and to find out how long they were; that is, if they were even for sale. They looked like they might have been cardboard tubes that linolium or certain types of carpet might have came on. The cardboard was about a 1/4 thick, so they would be durable. Those would be perfect for making my own Tube Traps or Gobos and if I can pick the tubes up for 5 to 10 bucks a piece; that'd be ideal. http://www.foambymail.com/soundproofing.html has fire rated foam that is reasonably priced. I could probably dress a few gobos with scraps from the other areas that I'll be treating.
Members Jeff da Weasel Posted August 31, 2005 Members Posted August 31, 2005 The one thing you need to be sure of is that it's an absorbtive material. Honestly, the more it seems like it would be a good sponge for liquid, the better it should be for cutting sound. Even carpet will have some amount of reflection. I've successfully used one of those foam pads you put under sleeping bags on camping trips. They're pretty thin, so you can take one, double it up and wrap it around the front of a guitar amp. Works fine. When I used to multimic drum kits (and before the DAW editing and sample replacement days), I'd even try and get better isolation between various parts of a kit with little mini-gobos we'd make. - Jeff

Members blue2blue Posted August 31, 2005 Members Posted August 31, 2005 Originally posted by Johnny Storm You aren't referring to Leo's Pro Audio, are you? As far as I know, the Leo's here in Oakland is their only store. Is there actually a chain called Leo's that also sells pro audio gear? No, no. Actually a consumer stereo (car & home and later TVs, VCRs, etc) that was probably limited to southern California. They had whole page ads in the sports sections. Very Crazy Eddie's -- only, as far as I know, there never was a "Leo" in the Mad Man Muntz/Crazie Eddie mold. But you could get some decent deals as long as your steered away from their house favorite brands... you know the kind, nameplates you'd never see at another store... or oversize and wildly overpriced speakers whose inflated prices were used to deliver package deals with exagerated "list prices." Great place. Lots of memories...
Phil O'Keefe Posted August 31, 2005 Posted August 31, 2005 GOBO = Short for "Go Between" - acoustical devices designed to partially isolate instruments and / or offer acoustical space modification for recording purposes. Ani, Jeff is absolutely correct - unless you're planning on finding acoustical panels for control room treatment (such as ASC Tube Traps or the Primacoustic panels you pictured), real gobos (the type usually used in TRACKING rooms to seperate inividual instruments) can easily and rather inexpensively made from 2X4 lumber, some plywood, some acoustically transparent cloth (colored burlap is an old studio favorite) and some semi-rigid compressed fiberglass. Construct the frames out of the 2X4's, so that you have a wooden frame that is roughly 3.5" thick. Add the plywood (heavier is better) on one side. On the other side (there should be a cavity there), you'll attach the semi-rigid compressed fiberglass. You should go several layers thick - semi-rigid fiberglass usually comes in 1 or 2" thicknesses, and in 2' X 4' sheets. Fill the "cavity" with the fiberglass and cover with the fabric. You can varnish and / or stain the plywood side, or cover with fabric too if you prefer, but I'd recommend leaving it sans the fabric - that way, the gobo is "reversible", with an absorptive and a reflective surface. You can make the bases out of additional 2X4" lumber, and add wheels (available at Home Depot) for easy mobility if you so desire. I'd recommend 4X4' gobos... which means a single sheet of 4'X8' plywood, sawed in half (Home Depot can cut it for you if you want) will yield enough plywood for two gobos. If you want absorptive on both sides, you can attach 2X2" lumber to each side of the plywood, thus creating a double-sided frame... attach the compressed fiberglass (or mineral wool - either will work fine) to BOTH sides and cover both sides with the fabric. Either way, you wind up with great gobos that should cost LESS and that will probably be more effective.
Phil O'Keefe Posted August 31, 2005 Posted August 31, 2005 Here's a link to some more commercial gobos. You might get some useful ideas from that page. Also, the semi-rigid compressed fiberglass can be difficult to find. You're looking for Owens-Corning Type 703 (or equiv. - several other companies make similar products - Knauf, Johns-Manville, etc.), but you won't find that at Home Depot - look in the phone book under "Insulation contractors" or "insulation wholesale" and start calling around. Or, you can use mineral wool - which is available from Auralex - www.auralex.com

Very Crazy Eddie's -- only, as far as I know, there never was a "Leo" in the Mad Man Muntz/Crazie Eddie mold. Geez, Blue...first it was Gemco and Zody's and (gasp!) White Front. But now you've gone and mentioned Leo's Stereo AND Muntz in the same sentence... ...and I realize just how old I've grown in the same place. Yikes...anyone for the Helms Man?
Phil O'Keefe Posted August 31, 2005 Posted August 31, 2005 Yup - Helm's Bakery. Yum! I remember Leo's Stereo too. And all the other "only old people can remember those places" stores you fine old folks mentioned. I don't think anyone mentioned Fred Rated (Federated) though....
Members felix Posted August 31, 2005 Members Posted August 31, 2005 I'm floored at how many people are defending the MF clerks, or criticizing Ani for expecting some simple customer service. Ask the clerks' boss what he's paying them to do. I bet the answer is very simple, and along the lines of the service Ani expected.
Members Billster Posted August 31, 2005 Members Posted August 31, 2005 Originally posted by Ani Bill, Yes, indeed, this is an advice forum... but I WASN'T ASKING FOR ANY ADVICE HERE I was blowing off steam about piss poor salesmanship!!! Then post on blowing off steam/ranting forum. My opinion is that salesmen's personalities are not worth getting ranted up about. Originally posted by Ani You do not have any idea how far along I have progressed on my studio... not even a clue!!! You have no idea how much money that I've spent or how many different contractors that I have hired and dealt with over the last several months. You seem to be on some sort of a power trip here as to thinking you need to tell me how to run my personal business. No one has been asking you anything here... what's your trip? So the garage door is gone? My trip is that you have posted all kinds of information on this renovation project, and I'm curious as to seeing an end result. I steal ideas from everywhere. You're fortunate to have a garage to remodel. I don't have a garage, but I intend to build one with an eye toward having some versatility to use it for a tracking space when my car isn't in it. It won't be ideal, but it will be better than blasting an amplifier within the house. As for "power tripping" that's your interpretation. I have participated in studio build-outs, and also lived through the analog-to-digital revolution, so I've seen a lot of retrofitting in my day too. Maybe I have a hard edge to my writing, but remember that I'm probably ;)ing more than :mad:ing Originally posted by Ani .... but that's not really any business or concern of yours. Which is why you typed all that description, right?
