Ok so the woodshop came back to me and told me that the "Sugi" wood wont be enough strength for an amp..

I'm left with two options for the head and cabinet:

Mahogany $300 cut and plane (18-20mm)
Alder $160 Cut and plane

Anyone have experiences with these woods for tone?

Best Regards,

So guys I got the African mahogany and been cut to 20mm. I'll be finishing it in satin. Back plates and the front plate for the amp will be figured maple. Thinking if I should put a hold through for ventilation. If anyone has a design let me know haha. I've also made my own finger joint template haha :D and one that's the ukulele I made for my girlfriend in the back :lol: I'm hoping to finish this in a week. I'll be finishing it with satin watco wax but will be using oil stain to darken it up a bit

Update"

Building in Tokyo is a pain. The tools are hard to find and mostly out of stock because people don't do much DIY here. Even looking for the router bit took the whole day. What coul've been done in 15 mins became 10 hours haha. OH The joys of DIY in Japan. Electronic wise, plenty of shops here.

Anyway Finger joint complete, but due to the router bit being cheap (And the only option), it chipped off a lot of chunk from the joints haha. But its a good thing i kept a block of wood with me. I'll be chiseling them to shape and gluing them between gaps.... Last bit of 1/2 inch to be done today and the chip repair begins. After that just the finishes. I'll be using watco wood finishing oil and waxing over it later on to create the nice satin furniture look. Figured maple looking sweet as well.

Finger joints and dovetails can be a bitch. Best to back both sides with sacrificial wood.
you JUST KNOW some Tory wanker has thought of this idea already. Probably getting the inspiration whilst fucking a dead pig.

oh and always do a test first if you can - make sure you buy more wood than you need. Its easy to think of this stuff in hindsight, which is why I prefer to tolex/tweed cabs.

haha thanks for the heads up! its actually looking good now.Filled the gaps with the same wood by chipping the same size away from a spare block. Can't even tell the difference :) I'll be sanding it today then sealing the wood before rubbing it with some satin coating from watco. I'll be testing the finishes today hopefully it'll turn out fine.

So guys,

I found some spare walnut bits about 10mm but enough to cover the inside of the cab ... I will add it to both front and back of the cab. Maybe 45mm to the back and 15mm to the front to give that extra mojo.. Now the question is, should I line just the outside of the cab(option A) Or frame for the sides and full the top and bottom(option B) or full on walnut to the inside of the cab (makes it 30mm thick haha(option c). see drawing. Any idea would be helpful. This is for the aesthetics + tone of course.

Thanks haha. I did a quick 3d and found similar colours(texture not accurate). Will look something like this. Colour matched better in real life haha. I will continue building it this weekend. Tried to keep it small for the 2w amp.

Regarding the mesh, not sure what colour yet. Any suggestions would be welcome 😊
