It's always been my understanding that with the pot's shaft pointing towards you and with the solder lugs down they are numbered 1, 2 & 3 from left to right.

Isn't it lug 1 of the volume pot that gets grounded?

This same mod is called the fingernail polish mod on another forum. No cutting required. Just open up the pot and place a small drop of fingernail polish on the resistive element inside the pot where the pot's wiper would be when the pot is turned all the way up. It works great!

Since I haven't gotten a response I'm guessing that I can't get just a bare chassis. Are there any other options out there? I've tried Kombo King (or something like that) a few times over the last year or so and have yet to get a reply. At this rate I think I'd be better off buying the raw material ...

One of the reasons I want to machine my own chassis is so I can use this AC socket with an integrated fuse holder. I've used this on all my builds. This allows me to have everything on the back of the chassis flush so there's nothing protruding out the back that can accidentally get broken off. [img...

Thank you everyone for your replies. I'm looking to buy a bare chassis without any holes. I prefer to machine my builds myself. I've built several amps using the Hammond 16x8x2 chassis. The iron for an Express will be heavier than any of my previous builds so a sturdier chassis made of heavier gauge...

Where can I find a chassis to build an Express? I did some searching here on the forum and several threads recommend AmpBuildersParts.com. I went to the site and all I find under "chassis" are cast aluminum Hammond project boxes.
