Hello,this is a project I did for my guitar player in our band. He had bought a used Marshall 1960 slant 4x12 cab and a JCM 900 50 watt head,they had alot of life left in them but were pretty well banged up.I told him to let me get some new vinyl and grillcloth and turn these into something to be proud of.I stripped the head and cab,sanded both completely clean,installed purple elephant vinyl,and Marshall check grillcloth,and put matching vinyl on the front panel of the head.I thought I'd
share these pix with you of the finished head and cab,enjoy..............Steve

            ps.pix are numbered in sequence but didn't load that way sorry

 Thank you,glad you enjoyed them,things kinda went nuts after this,my aforementioned guitar player,said he just had to have a 1960 style straight cab,so I built one to match the original Marshall slant that I recovered for him and that gave him a full stack,but that wasn't good enough,noooooo! He asked me to build another stack for him and recover a Marshall DSL 100 watt super lead he had just got from ebay,well  I'll let the pictures tell the story from here,by the way the original Marshall 1960 slant cab is the top left cab in the pictures,the rest  of the cabscame from my shop,(guitar players,I love em,they're nuts) enjoy the pix..........STEVE
ps.if they're any Marshall Lawyers planning to sue me,
these were given as a gift to my guitar player,for a sweet
1966 Jazz Bass,and no cabinets were sold with the Marshall Logo......STEVE

I am building a pair of Mesa oversize replica style to match my 2 oversize
Mesa cabs. I will post some pics when I can. I am covering all 4 cabs
with Wine tolex W/ Wheat Grill cloth, black piping with black corners. 
I think it will look nice when finished.

Was it difficult to remove the baffles from the slant face cab?  Any tricks I should be aware of? 

I'm replacing the grille cloth on a couple of slant faces (1960A) and just trying to anticipate any pitfalls. 

Do I need to take all four speakers off the baffle before I remove the baffle?

Hi,
The speaker grills are no problem to remove from the 1960 slant cabinets,follow in this order
1. remove all screws from back panel
2. tilt back the top of rear panel far enough to see
wiring to the mono-stereo switch jack plate.
3. take a photo or make a drawing of how wiring
is connected to switch,these just pull off,be careful not to break off a terminal on the switches  as you remove the wiring.
4.Now remove back panel completely and set aside.
5.Now take a photo or make a drawing of the
speaker connections and wiring,it must be re- installed,the exact way in order for proper
stereo-mono operation.See hint in # 8 - # 9
6.Now completely remove both side handles,get
a small jar or box and place your screws in these.
I know this doesn't make sense at first,but the handles must be removed,you'll see why.
7.Get a blanket or pad and tilt the cabinet over on it's face.
8.Now unscrew all speaker bolts at once and store
bolts in a different box or jar (now a little hint)
9.Take your back panel and lay flat with the wood side up,somewhere out of the way and safe,a friend would be a big help,but you can do this yourself,lift the speakers out of the cabinet and lay face down on your back panel,DO NOT
disconnect the wiring from the speakers,so when it's time to reinstall,no re wiring and they're wired
properly.
10. Now there are about 10 or 12 screws that secure the speaker frame to the cabinet,these
are two inches long and are around the perimeter
of the frame,remove these and store in a small
jar or box.
11. Now stand the cabinet back up,reach your
hands inside the cabinet and place them in the two top empty speaker holes,start to lift and at
the same time tilt the speaker baffle back towards
you,the frame is angled like the cabinet and there
is a gap at the top of the cabinet,where the frame will clear the side rails of the cabinet,now your
speaker baffle is out and ready for a recover.
Re install is the reverse of these instructions.
Good luck on you recover,hope this helped

Steve - thanks - very helpful.

One or two questions... 

Is it absolutely necessary to remove the speakers from the speaker frame(baffle)?  I know taking all the weight off the frame will make it easier to maneuver for the obvious reasons but I'm lazy and...

I am finding there are some pointy screws sticking out of the metal speaker frames (the circuler edge of the actual speakers) and these have nuts on them which secure the speakers to the baffel.  These look difficult to remove since a typical nut driver will not fit over the protruding pointy screws. 

Please note that this is not a true Marshall cabinet but a "knock off."  However, I am "practicing" on this one because I have two authentic Marshall cabs that I intend refurbish by replacing the grill cloths  and I don't want to mess those up.

Also, note that this speaker manufacturer was not kind (or smart enough) to provide the gap in the side rails.  The side rails are continuous and so had to be removed and hence will have to be carefully replaced.

Hi,
Wow,alot to address here,well lets get started
First up,speaker removal,I quess you could "attempt" to install grillcloth with the speakers still on the baffle,but even if they're just generic
speakers,your looking at close to 40 lbs. mounted
on the baffle that your trying to stretch and staple
and maneuver while you try to install your grill
cloth,in all honesty,grill cloth installation is a
project that requires patience and attention to
detail in order for it to be something you'll be
proud of and want to display,put it on wrong
and it will stick out like a sore thumb.
 
Okay,what you have it sounds like,is a baffle
with speaker mounting bolts (Fender still uses)
they go through the front of the baffle and
and have little tines on the head that digs into
the wood to keep them from turning,they are
threaded and stick through the speaker holes
and are attatched with nuts,what you will need
is a deep well socket on a ratchet ,check with
a friend if you don't have any automotive tools
and nicely ask to borrow one,the deep well
socket will fit over the bolt and allow the nut
to be removed,you'll need to find out what size
nut is.The bolts will stay in place .
Believe me,I've replaced grill cloth on over 40
speaker baffles all 4x12 and you don't want
to wrestle that baffle with speakers on there.
I think you have the right idea about practicing
on this knock off cabinet first.
Sorry to hear about the side rails,but every mfg.
is different,hope your project goes well,never
hesitate to ask me anything,if I ain't done it,then
I'll find out for ya,good luck,post some pics
so we can see when your done.

Steve:  OK, thanks - that settles it - you have convinced me.  I will definately remove the speakers.  I don't want to botch the installation of the cloth - that's my whole focus on this project.

Thanks again for the detailed response.

Just a few extraneous notes. This wood of this cabinet appears to all be some sort of particle board - otherwise, it is pretty heavy duty.  But I understand that a real Marshall cab is made of a high quality plywood.

Also, there are two Celestian G12-50s and two Celestian G12 -30 in this cabinet.  I can't remember the wiring confirguaration - series/parallel?  But what ever the wiring is, it is such that if one speaker goes out, the others will continue to function.  The total impedence of the cabinet is 8 ohms.  I'm not really asking a question here or even making a point but just making a note of what I have here.  When I remember the name of the company that made this cabinet, I will make a note of that also (I think the name started with an E).
