1x12 extension cab build

A while ago I had my Sessionette amp upgraded, and finding some spare 18mm plywood in my garage, I decided to build a matching 1x12 extension cab. The build was pretty straightforward - I used a router to cut the hole in the baffle, which was much easier than using a jigsaw. I used ivory leatherette to cover the cab and Fender Oxblood grille cloth. The speaker is a Jensen P12N which i had spare. Some pics...

Now I'll have to recover the Sessionette to match...

Very nice! I am curious as to why you made it an open back?

No reason other than I quite liked the look of those Dumble cabs, so while I had the router out I thought I'd give it a go! I may try a closed back, as I still have some spare plywood... :laughing7:

Thanks for all the nice comments. One day I'll make one as nice as "The Limey"!

Let's hope you don't make it as heavy :)

Cool! Did you screw in corner braces? Your lap joints may give under sizable, volumetric pressure.

 

You did a fine job. Especially around the rear opening; whaf!

 

Congrats.

Yes I did - I countersunk the screws and used filler to cover the screw heads. Next time I'll try dovetails... :laughing7:

 

I've also recovered the Sessionette to match - pics to follow!

Once you tune in your router and dove tail fixture, they are easy and reliable to create. Dados are fun too.

 

That cab came out splendidly!

Posted

Good job :)

 

Do the cabs lock together?

No, the amp just balances precariously on the cab. :)

That's inspirational.

I've been collecting pieces to a similar project and had almost given up.

 

Your results have given me a good shove off the fence.

Nice couple. They look happy! Success.

Looks great...I humbly suggest a removable back so that you can use it both ways. Can you you build me a Guitar Room?

Posted

No, the amp just balances precariously on the cab. :)

I see a large repair bill in your future :)

Nah, the four large rubber feet on the bottom of the Sessionette should provide enough grip!

Hurrah! One of the nice things about this forum is that it can provide inspiration and share knowledge. It's very satisfying to create something.

Does the lack of finger jointed make a difference in the cab? I have a 1x12 cabinet, that is actually nailed together. Sides are pine, but top is a chunk of flame maple.... Looks cool, but I'm not sure about durability.

I don't think so - having researched cabinet building on the internet, I found quite a lot of designs used lap joints reinforced with wooden battens. Mine was glued and screwed .together, and that should be strong enough - some woodworking glues claim to be "stronger than the wood itself"!

Having been enthused by building one cab, I only went and built another! This one is to go with my Ceriatone OTS. I was originally planning to use Vox Black Diamond grille cloth, but that proved hard to find so I went with Marshall "Chequer Board" instead.
