Was supposed to be making (my first) electric guitar and/or a cherry dresser, but due to corona virus lock-down I had to resort to something I could make at home.

This is what I made. Well OK, my brother did the electronics part, but that 1000 piece puzzle looked childishly easy ;)

The first iteration was out of pine, but I had my measurements wrong and the contents wouldnt fit! 19 mm (appr 3/4 inch) pine ”sheet” that you can buy from a big-box store was so delicate, that it kept blowing it up in the router. Or at the latest when I was removing the routing template attached with double sided tape. Or, since this seemed like a problem, routing over my line because the template was not properly attached. By the time I got the finished electronics from my brother and noticed the mismatch, I was ready to change the raw material to similar big-box store bought oak! That worked so well, that I changed course and ended up finishing this with Osmo oilwax instead of Tolex-wrap. By this time I also had my box-building routine dialed in due to repetition, repetition, repetition, and the oak version was ready for glue-up in less than an hour. My minimum sized pine sheets were so plentiful, that I wasnt too worried about making replacement pieces instead of investing in the proper process. With oak I didnt have extra, so I was a lot more thorough in preparing the routing of the opening for the front panel, as well as with the round-overs. At this stage I also changed the grill cloth for this cane version for a more vintage look overall.

That’s a great amp Antti.
The grill covering and the oak does give it a vintage look.
I like how you used vacuum tubes, which will give it a nice ventage tone.

Looks great! I’ve been meaning to build a wood cabinet for my Blues Junior. It’s on the (very long) list. :)

No way the pine version would look this nice or last as long, good choice! Great flexibility for you to make so many other accommodations along the way. End result looks great … thanks for posting.
