Brads Guitar Amplifier Isolation box Build Mark 1

[TylerVanderkooy]

I would have to agree with @dsl100stack . You would probably get a better sound if you move that to the middle of the isolation chamber.

[dsl100stack]

isn't the mic a little close to the speaker?

[lanzauno]

the key here is using a small watt amp. IT will pick up small nuances better than software and won't create the phase issues that a higher watt amp is prone to getting. 1/2 watt would do the trick. A high-watt amp like that marshall, even at low volumes isn't going to work in an enclosure that small. Simulators are cool, but I guess it depends on what your trying to sound like.  A lot of albums have benefited from a less than perfect sounding amp in recording. In my opinion

[lorddrag140]

Wanting to make an Amplifier for my guitar...With an altoids can.Haha.

[pegasomarcelo]

SEE MY AMP:

[ebeatworld]

A friend of mine built an iso box for my amp. It cut out the sound down of course, but I got really weird frequencies in there. I don't know if it caused phase issues or whatever, but it didn't sound right. Made my amp sound shrilly.

[14luisalonso]

nice job.. would you recommend a place to learn about proper speaker cabling and ohm capacity?

[SpeedPickers]

Hi Brad...I've just done a response with my last video...to promote and link together!

[duhhh187]

question: were did you get the foam??

[BRADHblackdragon]

@duhhh187 advanced acoustics-ebay uk

[merlinchanelle]

Wrong wrong

[GEARHEADGUY92]

WTF all the microphone is going to pick up is air turbulance

[MaxOsadchenko]

ВОт это да)))



[axxessdenied]

How quiet is this? Got a video of you playing through it to show how much sound bleeds through? I'm looking to build something like this to record with in my apt. Amp Simulation software still doesn't sound right :/

[BRADHblackdragon]

@axxessdenied @axxessdenied .dont expect miracles but fairly good.amp simulation is best i reckon now..amplitube 3 my fave,,,great room mic feature...where if you use just these and turn off close mics and use good headphones or monitors sounds like playing in a room like real thing.ik multimedia done a/b vids on youtube with real amps and they sound identical pretty much...im not affilated..amp sim leagues ahead than getting real amp now i reckon..e.g. in terms of cost

[callyatheoriginal]

@BRADHblackdragon

hey im from germany, my english sucks. Didi u answered the question "how quiet is it?" i just want to know how many volume i can swallow with this isolation box..

[stevoe1000]

@BRADHblackdragon Hey man, do you really think so, that GR sounds the same when recorded as an amp....I have GR4 and it does sound good but I can't say it sounds like my superchamp xd....it does sound good but something seems to be missing with the recordings...like fullness of tone and some other things....

[dannyhood66]

This song and album is by far some of the best neo classical metal of all..The album cover did not give it justice..Maximum security

[BRADHblackdragon]

@dannyhood66 yeah its one of my favourite guitar instrumental albums

[CardboardNinja7]

why did you put the mic in the cab

[aaronkswafford]

I built one of these JUST like this! Hahah

[BRADHblackdragon]

@aaronkswafford have u a video of your box? i cant see one on your page...have u still got it?

[PoftheBR]

That's terrible mic placement, have any recordings?

[BRADHblackdragon]

@PoftheBR hi yeah, mic placement was just temporary..no recordings im afraid

[killersoundz]

@PoftheBR LOL yeah...yikes

[r33d2k]

dude you should make a vid of it in action

[BRADHblackdragon]

@r33d2k hi ,i havent the box anymore..it sounded great though..although guitar sim software now is well on par..iuse that now..the likes of  guitar rig 4 and the recent amplitube 3

[r33d2k]

fair enough mate, my friend uses progs like this, quick question its probably dumb because i'm one of those people who plays guitar but doesn't know anything about it XD is there a way of hooking up my guitar to my pc without using a pod or something, basiclly without spending a wod of cash. i do have a line6 spider 3 75 watt with all the presets n stuff, but there's no room for it in my tiny bedsit :p

[BRADHblackdragon]

@r33d2k well a great way is the alesis guitar link..its literally a guitar jack on one end and a usb link on other.the sound quality wont be fantastic but it'll do.next after that would be a stealth plug by ik multimedia or the guitar rig mobile,i guess

[r33d2k]

thanks for the quick reply dude, do you think the sound quality would be better or worse plugin it into the mic jack instead of using a usb lead

[BRADHblackdragon]

@r33d2k it isnt necessarily better..one factor here is the conversion...from analogue(your guitar)to digital(a form that is needed for pc to process the signal)this is done by 'converters' which vary in quality.

its more a case that u might not be able to just plug in to the mic jack..ive tried i think and i couldnt get to work..i think because the signal is too weak for your guitar software or daw to work with

[r33d2k]

this doesn't really answer my question dude, i kinda wanted a yes or a no, not i tried "i think" lol, so i know if its worth buying the adapter or not.

[axxessdenied]

@r33d2k Check out the JamLab by M-Audio.

[highspooky]

thx skywalkerfamily

[zakkthemusicdude]

What does an Iso cab really? I have never used one.

[highspooky]

cool video, but in your box you havent got enough variation for your mic position, because you have a fix mic stand. better will be a "swan neck", i dont know how you call it in english. havent you enough money for some correct input/mic jacks?

[Skywalkerfamily]

@highspooky I think that would be called a goose neck.

[scottyBoland]

hey dude would the foam material make a massive difference? and if so where can i pick some up? and for how much? thanks man

[BRADHblackdragon]

@scottyBoland .its not primarily designed for dropping volume...although it does reduce it...its more to cut reflections ie reverb so sound is just the miked cab and not miked cab and reverb created by that..the box primarily is for dropping volume...try going on ebay to start a search

[scottyBoland]

ahhh well i was just wondering i once dismatled an old jbl l100 century 3 way speaker, from the mid 70's? it was a really popular speaker at its time my dad had 4 so i took the one with most abuse and took it apart the box was stuffed with an insulation like material, so i was wondering if that like the foam you used would make a difference from a hollow sound too a deep sound, like i took it out played it and vice versa and it was deeper with it in, and sounded fuller

[tex8252]

thats a great idea...very original

[b7sus4]

hi, whats the name of the song please?

thanks

[4JayeP]

@b7sus4 Tony MacAlpine, Tears of Sahara.

[immanrobinson]

Why did u put a mic inside the box? of course to amplify the sound but u can directly plug ur guitar in that amp rite? jus asking...

[mackk123]

this seems totally rad :D

but why put the speaker in a boxx???

[olalator]

to play LOUD for records and have silince around ( i think )

[keeelane]

don't you need ventilation, tho?

[BRADHblackdragon]

yeah good question.for a variety of reasons- ideally..e.g. speakers push air which shapes tone..this is hampered with isobox..no need to worry about damp..just open periodically..the heat could get up in there on hot day...use a thermometer if u like but no real worry as i dont think speakers heat up much

[strongbad20212000]

Holy crap, I have never thought of this as a way isolating my guitar amp before. Hell, I was gonna pad my whole closet up and use that to record, but damn it, you've just saved me closet space!

[MrChrisPid]

Wow! Good Job BRADHblackdragon!

I also wanted to build such a cab. And then I found your vid.

Could you post sound samples, please?

[andrew0901280]

damn ive never seen a setup like this before.

hows it sound?

[BRADHblackdragon]

a speaker pushes air-this relates to the sound it gives off...an iso limits this pushing if playing at ultra high volumes...other than that its the preferred setup..e.g. reduction of ambient noise etc..the sm57 worked a treat for me..e.gsome use inferior mics..i tried not to skimp on that and the speaker

[turntapzap]

Nice rig.

[plakata1]

Could you tell me a little about the dimensions of the box?

[BRADHblackdragon]

hi,ive now added a descrption of build to right..hope this helps

[plakata1]

Pretty cool. I want a box for my 4 x 12 marshall. Going to be hell to make.

[BRADHblackdragon]

work should be about same for 1x12 iso box...its just bigger i reckon..interested to hear how your build goes

[christhekiwi12]

whats the point moron

[azraaell]

what is this, why you put speaker in and totally seal it up, is that a mic in the box?, nice workmanship btw, i have a 10" p,a, speaker do i just need a preamp or a poweramp or bot or is there more i need? thx hope you can help

[BRADHblackdragon]

reduces noise from amp and reduces reflections..the first is for where you cant play a loud tube amp at high levels and the second is so as to get a good recording..e.g. no background noise...it just an amp head into the iso box connecting to a speaker...its miked and then sent to a mixer and then into my pc via soundcard

[mycrimsonregrets]

you need a preamp and then connect that to a power amp. a mixer and power amp should do you fine. the preamp boosts it to levels high enough for effects, eq, recording, etc and the power amp boosts it to levels high enough for the speaker. good luck.

[JeezoozeChrysler]

Great job man ! BUT how does it sounds? can we hear ?

would be much appreciated ! and what's the song in the background ? thanks a lot

[BRADHblackdragon]

sounds great .but dont expect the impossible

[killdomokill]

what are the dimensions of your box? im planning on building one and i cant really find any dimensions other than the one for the randall iso box which is 18inx18inx31in.

[cmorrow132]

And how much did it cost to build this?

[BRADHblackdragon]

about 300 bucks

[cmorrow132]

I live in an apartment, and my neighbors are just on the other side of the wall. They complain about the volume of my amp if it is over volume 3 during the day. So, I'm stuck recording straight into the mixer -which sounds like crap. How loud is the sound from the outside once youve closed it up? I'd like to mic my marshall avt-20, but i need something that leaks little to no sound - i do most of my work late at night.

[BRADHblackdragon]

hi well i was playing a jcm2000 in my apartement...couldnt hear speaker above the computer fan but then again didnt have amp way up....u may be pleasantly surprised..i was but please dont expect the impossible

[johanneslabusch]

Is that a design for Zakk Wylde's coffin?

[cptpipp]

depending on how loud your recording, you really shouldn't put the mic that close to the speaker cone. especially when it's pointing directly in the centre, because the cone exerts very high Sound Pressure Levels, which can easily ruin the diaphragm of your microphone. Just a tip. Since it's in an isolation box you don't need to worry about room echo. It's best to keep the mic at least 4-5 inches away from the speaker.

[withoutawordwv]

Actually close mic'ing is probably the most used method of electric guitar recording

[luigiperso]

excellent work. And a soundtrack to boot from Macalpine :)

[stymye]

would the (packing?) foam be packed the other way to break up the acoustics of the square chamber.?

[dannyrusse11]

So cool to share! I'm gonna build one myself. I heard they can sound a little 'boxy' - what do you think?

[gukobi]

that was sweet. you rock!
