anyone Mojo Cabs ??

I guess I got lucky with my mojo 4x12 (except for the rattling backplate that is)

To be fair, Mojo makes lots of cabs, they're not all built the same. Here's my experiences of the ones I've owned/own.

1x12 w/BB reissue cloth. Oversize 1x12 width (26.5"), 10" deep, 22" high, open back. The baffle board on this one is 1/2", or perhaps 7/16", but it flexes. If you push on the back of the speaker magnet you can hear the baffle board make a crackling/squeaking noise. No amount of tightening the baffle to cab mounting screws stops this noise.

2x12 OS Bluesbreaker style cabs, 12" deep, 31" wide, 24" tall, closed back. No issues to speak of, but it came with a few stripped baffle board screws which were different lengths (WTF?). I generally don't buy a cab then have to fix it's hardware.

4x12 cabs, I've had three, one is still here (made for Aiken). Multiple issues with the other two. I had to dowel many of the baffle board mounting screws where they attached to the front lip. When doing so, I found that there were standard #8 x 1.75" screws along the top, changing over to 1" long screws at the bottom, most of those were toast, and had to be redrilled/doweled, and 1.75" screws back in. And they had a weird midrange tone, that I just figured was either the wood/cloth, or the way it was built.

The Aiken labeled Mojo cab I still have. It had the loose back plate, Roe (WTF?), and I wound up making a whole new back panel for it using my adjustable back design. This cab is still with me, and I use it for testing speaker mixes. It sounds good, but it also has more baffle mounting screws than a regular Mojo cab and they all have a rubber washer under the screws that mount the baffle board to the front lip. Maybe Randall knows something we don't about Mojo cabs.

I've heard two good Mojo cabs that clients got, but out of about 12 I've heard/had that's not a great average. I'm not sure what the deal is, as they should be real close to what my cab guy (and probably Germino's cab guy, Metro and Stone Age) build for 4x12's. But they aren't the same tonally, exhibiting a weird midrange tone.

So if the dimensions and build are so close, with equal joinery/soundpost size, etc, the only differences should be the wood used and the cloth/tolex. I've finally concluded that whatever they're doing isn't quite right.

As stated, my opinion is based on hearing around a dozen Mojo cabs, all with good speakers/wiring/jacks (something I obviously replace/check on every cab).

So I'm not sure where/how they get their wood, but I just use 5/8" furniture grade (the highest they make) baltic birch with Marshall tolex/cloth.

My Mojo experience at this point and time is mixed. 4-5 years ago I had Mojo make a custom 4x10 combo cab to fit my jtm45ri chassis. The cab was good except during communicating my expectations through email, I detailed my desires for what I wanted. Many times when I did get a response, it was a one word email , like "ok".

When I recieved the custom cab, my expectations were not met. I had expected a valance above the grill cloth, that was not provided. At the time the mojo rep required me to send him my chassis to garuantee fitment. After I sent him my chassis, I emailed asking how it fit. His reply was "I forgot to check it, we already sent the cab out".

I ended up keeping the cab as is, no discount for the errors was offered or given when asked. Other than these issues the cab has been fine and sounds good.

My most recent project has been a 5F6-A tweed era Bassman. At the time, the Mojo pricing it what lured me back. The cab is well built other than, the handle wasn't centered properly and the tweed was layed over the sides into the interior too far, covering more than half of the cabs interior sides.

For mass produced cabs they are ok, but like many mass produced items the attention to detail is lacking. Next time I think I'll just nut up the extra money.

Jim and all,
I have also a MArshall 2x12 1936 cab... its all made of cheap wood how can I increase the bass response from this cab (using preRola 25w 75 hz Greenbacks and aiming to maintain defined tone) ???
I dont have money to spend for another 2x12 as Im in search of a bottom 4x12, I was thinking about reinforcing with wood some parts of the 2x12...
thanks a lot for any help

I'm not sure what to do for that cab. The old ones made of baltic birch had a weird midrange thing happening, although it got better using G12H30 bass cones in it, but that's not what your looking for.

Later 1936 cabs were made of MDF/particle board, so they're odd sounding, too. You might try putting some fiberglass insulation in the back of it to deaden the soundwaves but I'm not sure if that's going to get you the overall deeper tone you want.

Those cabs were just odd, or at least the three I had were, so I'm not going to be able to help much since I sold them. Sorry.

thanks a lot I know its a very cheap thing I'll try experimenting

At the beginning of the year I ordered a straight 4X12 in red tolex. It arrived in perfect condition and it very well built and sounds fabululous, absolutely no issues and is by far better built than any new Marshall cab made with sawdust and glue.

No worries indeed! Mojo make solid stuff.

I've own three Mojo 4x12 straight cabs.

The first 2 I bought a couple years ago I found them to be pretty good build quality. The only problem was the 2x4 brace between the baffle and back panel to rattle when having the amp loud. So I just put a screw in there.

This last one is not as good imo. Same thing as before but now the grill cloth is not as nice looking as before.

Have never compared them to what jim has just to my Mesa cabs. IMO from what I can tell the Mesa's are built better.
