Hello!. I aquired a 4 12 marshall cabinet for cheap that had the tolex ripped up badly. It appeared the previous owner actually tried to rip it up on purpose. So it did not look cool. I decided to remove the tolex and then realized the tolex may have a hand in the strength especially where the sides interlock on the corner edges. I like the cab in this video. Does removing the tolex impair the durability of the cabinet. Thanks!
Can't say with your cabinet the effect of integrity after removal of the Tolex. It could be very little or a lot depending on how well the wood working was done. In our cabinets it would have no effect. I recommend you totally strip the cabinet down. Sand it well, It would take about three to five beers worth of time. Then varathane the cabinet with an oil based satin finish. Put it on thin, three coats will improve the cabs integrity. The varathane will yellow nicely.
You obviosly know a lot about cabs. I want to convert my Marshall Mode four cabinet (400w, 8ohms., 4x12 Celestion G12K-100) to a Stereo cab. I want to install a 1960 cab. plate; i know how to wire it and all, but wanted to ask you something about the construction of the cabinet. If and when i convert it, will run into any sound issues?Does the 1960 cabinet have seprate chamberes for each speaker because it is a stereo cab? Thanks.
I'm seriously down right pissed off with any company calling a 412, a "Stereo" cabinet when it actually doesn't have a wall to separate the cabinet into two (Stereo) chambers. You have the waves of one channel bleeding into and THROUGH the cone of the other speaker. They put in a $1. switch on the jack plate and boosted the price by $50.
The 1960 and most companies claiming stereo, don't have a chamber wall. Our DCE412 is a true stereo but cost 25 million dollars.
If your a very good wood worker you can add a separating wall. It will involve a lot of bracing for the wall to be anchored. Problem is your center wall will have to be removable. If you ever want to repair the grill cloth, you will have to remove the baffle wall through the back along with the new wall. Depending on the quality of your fit, you may get buzzing, especially with k-100's (Love that deep tone) I recommend you look out for one of ours used. LOL Or drink more Beer.
@ac23AQ The cab is wide open similar to the cab in this video...Be careful tilting the back pannel off it's secured by the middle screw thats in the middle of the cabinet and yes Marshall dosen't give you much streching room after the back is off..
I rewired my M cabs using heavier gauge wire and metal clips purchaced at Autozone after I swapped out speakers...
You can use any watts speakers combined but the ohms have to be the same. 30 watts gives you faster break up but you loose bass.
Hi, Jerry This may interest you, I have a Peavey guitar cab 1990's when my apt flooded, the two bottom speakers had water on them up to just below the center cone. It sat for a day like that.
I let it dry out for a week and nothing was damaged.
Do you think they may be ruined? they don't sound weird or anything and seem to work fine, they are Celestion G12K-85. They are at least 15 yrs old. This happened three years ago by the way.
Interesting. Speaker cones are relatively tough. If the water didn't soak into the voice coil and didn't cause corrosion and most importantly its sounding the way you wouldn't it, I don't see a reason for fixing something that's not broke. I would recommend you spend the money on Beer and Chicks. That's just my professional opinion.

G12K-85 is one of my favorite sounds. The G12K-100 is the same speaker.
I'm Eloy from Spain. You once helped me with a doubt and I hope you can help me again. I have a marshall complete stack, I mean 1960A and 1960B and my amp it's a Marshall JMP 100w from 1978 model 2203. And I have 8 speakers. 4 G12T75s from 1984, two G12 65s from 1981 and two G12H from 1976. I use the stack in my rehearsal and only the 1960A onstage. So, how would you load the cabs? Thanks a lot again and greetings from Spain. Eloy
Dear Gerard, I mean which speakers would you install in my cabs according to the speakers I have and taking into account that the whole stack is for my rehearsal and only the 1960 A cab is going to be used onstage. I thought in installing the four G12T-75s from 1984 in the 1960B and the G12 65s from 1981 and the two G12H from 1976,in a cross in the 1960A, this one is going to be used normally alone onstage due to trasport. I'd used both, but I've got a small car.Thanks a lot indeed Eloy Navarro
today im meeting up with a seller to buy a 1960B cab and had my drill ready to take the back off the cab, 2 make sure there were in fact 75's i am buying.
pheww!! im glad i saw this video before i did that to some strangers vintage cab!!! lol talk about dodging a punch!! always listen to people who have been here longer than you lol and being older is wiser my friend thanks
mr doyle, i have another question i did end up purchasing the cabinet and everything is beautiful on the inside, its a cab from the early 90's and i do not see any cocking on any angles, should i cock the walls?
If it's a Marshall, it was never designed to have chalking. The Baffle is removable as is the back wall. The gable to top and bottom walls use to be done with finger joints so if it's the older design, Good , they don't need chalking. This removable wall and baffle design, is problematic. Permanently installed back and baffle 412's actually will sound louder.
Bottom line. Just make sure all the screws are hand tight and that's the best you can hope for.
oh great thats good news, again i appreciate your info im signing up to your channel lol youre a great guy educating dummies like me haha thanks again .ill spread the word
The only dumb question is the one that's never asked. I've been in the business for more that 30 years. I can honestly say my trust for knowledge has never been greater. I deeply appreciate learning from anyone. I don't care how stupid my question may sound, I just got smarter with the answer.
There's so many tech things about gear that you need to know to deliver the Magic in your head.
Keep asking. I'll answer and Thanks you for the Music my friend.
What you have, I believe, is a sub woofer seen mostly in car and home theater. I don't know why you would think it could replace the Mids you would get out of a dual 12" combo for guitar. That being said, if you try it and like it, who am I to argue with what makes you sonicly Happy.
Yes this is true of every guitar cab we have seen, but we ourselves have learned from this "design flaw" (for lack of a better word.) We put a metal tie strip across our cables to reduce the risk of damage,(Get it in plumming supply for holding pipes.) In other cabs we tie the wires in a loop so there is some play when you pull it out yet you can push the wire back into its loop when reloading the drivers. It helps to be around for 30 years. LOL
If only I had seen this BEFORE I opened my cab the first time...

Tought Question..Can I use a dual cone 10 to replace a 2x12 combo?
I mean hook up a right x- to x- to the same speaker...
I have a 10 inch woofer with 2 side to it!
joeydahlia 2 years ago
Sorry but I don't understand what you are using or how you are wiring it. But I would like to understand. LOL
When you say dual Cone, what do you mean? Do you mean Dual Voice coil?
When you say "..right x- to x- " what is "x-"?
Identify your speaker terminals as "red or hot or Positive or +" and your ground line as, "Black or ground or common or -."
And I will try to answer. Other wise keep in mind what ever way it's wired, it sounds better with Beer.
Thanks
