Hammond 1590N enclosure - I didn’t know there are two versions of it!

[Flying]

Has anyone else bought a Hammond 1590N only to discover it wasn’t what you were expecting? The damn thing has ribs! I ordered three of them, the one I wanted, and had obviously bought before, was a 1590N1. I had no idea there was this other version! Thankfully I can just slide a piece of paper between the edge of the PCB and the ribs, that was pure luck! And it wasn’t fun drilling them out for top jacks and the DC power socket, the drill bit wanted to drift away when it was partially cutting into a rib.

I just thought I’d post this in case anyone else, like me, wasn’t aware there are two versions of the 1590N enclosure.

Not mine

Great for smaller-board 1-or-2-knob builds such as Fuzz Faces. Slide the PCB down the slots as per their intended use and use the PCB-pin mount pots.

That's cool to see an OG hanging around. I think a lot of my projects back in 2010-2013 were ribbed for my …utility.

Speaking of, I went way too hard on the 125B clone of a clone of a clone of a 1590N/1 rabbit hole a bit ago, but somewhere in my flurry of text I think I pinpointed the year they switched to the N1 not ribbed version: 2010, I believe.

Most of what we buy today (unless it's direct for Hammond) is a clone of a clone of a clone* however.

tl;dr
Circuit Specialists (under a different name) back in 1997 commissioned a Korean (or was it Taiwanese ?) company to clone it, sans ribs iirc, as the 03-125B. Which later became cloned and more popularly known as 4S125B made by 4site (not sure if they cloned the 03- model or cloned direct from Hammond) and sold at other places including mammoth electronics (who bought 4site it seems). Then it just got cloned again and shortened to 125B over the years, furthering the cloning of a clone, etc.

But yeah, McRib in the beginning, smooth introduced in 2010.
