    MGA412 cab with JTM60 head & matching 2x12 cab?
    Hi Guys

    I was after a little more bottom end for my JTM60 head and I wondered if this would be ok to do...

    I have a 2x12 cab for the matching JTM60 head which sounds great (to my ears that is), but I could do with a little more bottom end (not Satans Bowls bottom end for drop tuning metal though). I have seen a MG412 cab on sale locally for a very nice price. I have heard very mixed reviews about the speakers. However for the very cheap price, condition and compact size (absolute must to transport) I though this would be a nice option as the the JTM head has a 8 ohm output and a 16 for the 4x12.

    So, the question is would this enhance the sound a little? I don't want it to take over but I thought would be a good match for the 60 watt head? Would it overpower the 2x12 too much?

    If anyone could pass on any thoughts that would be appreciated. I know this isn't going to compare to any classic JCM900 / 1960 etc... setup so please keep it relative.

    Thanks

    MG cabs would not supply more bass unless you swap out the speakers. The MG speakers have tiny magnets which equates to less bass especially at higher volumes.

    I have one and I switched out my speakers and now have 4 greenbacks which sound great.

    What speakers are in your 2x12? Maybe you could upgrade those?

    Hi

    Cheers for your advice. It's nice to hear some support rather than a slagging off of anything that isn't JCM related.

    I will have a look at the speakers in the 2 x 12, I think they are Celestion Heritages.

    Thanks again.

    the stock speakers in those MG's stink. they are celestion speakers in name only, and you cant give them away, nevermind trying to sell them. they are low efficiency, and rather dark sounding, not bassy, but dark. not to mention the cabs are made of pressboard.

    i would hold out for another decent 2x12 or leave it as is.

    actually, if you want nice bass response, swap one or both of those heritage speakers for the G12-75T, the speakers that come in the 1960's. part of that big full response of a 1960 is those 75's.

    some people complain about the 75's, i find they are a great sounding speaker for exactly what your looking for, better bass. even better would be to pick up another 2x12 and run 2 75's with your heritage 60's.

    i bet you will love it, id even go so far as to guarantee it.

    after swapping speakers in that crappy MG, you will have more money tied up in a sub-par cab, than you would to get a decent 2x12 and 75's. not trying to sound harsh, its just a fact.

    ps, i speak from experience, i still own an MG 4x12, (b/c i cant sell it, no one wants it), i have swapped multiple speakers in and out of it, and yet it still sits in the corner, unused. i actually have a jtm60 1x12 combo, that i run with a homemade 2x12 loaded with a V30 and a 75, along with the combo's heritage, 3 speakers, it sounds great, with nice bottom end, even from my homemade cab (made from real birch ply, not pressboard)

    I have no experience with those Heritage speakers. G12T75's are good speakers, good bass. Not much speaker breakup. I upgraded mine to Greenbacks. I like their tone better.

    I am actually selling a pair of G12T75's on EBAY right now. These are the older made in England in the early 80's with vented magnets. They were warmer than the newer G12T75's since they have aged and been broken in. PM me if interested.

    the heritage is really nice, imo. its the 60w version of the greenback. very smooth and easy on the ears.

    I also have an MG412 cab and as others have stated it sounded awful. It is physically quite small (for a 4x12) and I had a pair of Celestion Vintage 30's lying about so I fitted the pair and blanked off the other two holes and the sound was transformed! I also managed to sell the standard speakers on ebay, they seemed to attract attention just because they have Celestion written on them.

    i loaded mine w/4 v-30's still didnt care for it. im a firm believer that a well constructed cab, made from real wood, will always sound far superior to a pressboard construction, and is worth the extra cost, provided you go used and find a good deal.

    v-30's wont help with low end response either, they provide a big mid-boost, but for my money, those 75's sound fantastic to provide bottom. a v-30/75 combo will give you both good low end and mids to cut thru a mix.

    its a great combination.

    Thanks for all the great advice guys, very much appreciated. I must say it was the price and size of the cabs that attracted me. Space is very important, in the house and car too! The mrs will freak if I brought something in on wheels! The 1960 cabs are quite big aren't they. Pity about the MG412 but the smaller cab with 4x12 seemed a good idea. I'll take your advice and stay clear of them.

    Okay, as an alternative how about a 1965 4x10? Beefy enough? I'm not after huge sub bass or anything just something that will have some presence. What I'm trying to do is use an angled bigger cab like a 4x12 or 4x10 so I can hear myself, then next to it at the side run the 2x12 for some extra umph with my tweed fender blues deluxe on top of the that for the twangy clean stuff, again so I can hear myself as it would be raised off the ground. Also I thought it could look quite cool with the different speaker cloths going on / three different colours! Sorry, not majorly important but I kinda like it.

    Cheers

    Watch out for impedances! If you run two 8 Ohm cabs you need to plug both into a 4 ohm amp output

    Consider an 8412 also, see other thread in this section.

    i can tspeak to the 4x10's. i knew a guy who ran one with a jcm800 way back, and it sounded great, but thats my only experience with them, listening to someone else and it was a long time ago.

    a nice wooden 2x12 with diagonal speaker mounting, so that its slightly 'oversized', with a partial open back, loaded with 75's will sound huge...it will 'bloom' when turned up loud enough to drive the speakers. not sub bass, not overpowering, but just a nice balanced tone. if your running it with your heritage loaded 2x12, even better.

    i was chasing nice low end response for months, i dont play metal, i play kinda clean tones, with an edge of breakup. classic rock type tones i guess. i run my jtm60 on the clean channel with the channel volume on 10, i try to get the master at least 1/2 way when possible, to give you an idea of the amount of gain i use. no pedals, straight up tube rock.

    anyway, i tried everything, different amps, diff cabs, diff speakers, my other guitar player had GREAT tone, big, full, powerful...he plays a stock 1960.

    i finally got my hands on a couple 75's...bingo. i have bottom end now to match the highs and mids. its balanced, and it 'blooms' at rehearsal volumes.

    seriously, borrow some if you can, do some experiments, i cant recommend the 75's enough for what your looking for. theres a good reason they come standard in the 1960's.

    and you can probably find a used pair pretty reasonably priced from someone who is "upgrading" their 1960 with greenbacks or v-30's.
