Sounds like you might have used an audio taper pot for the tone control. Look on the face of the pot, next to the shaft. Does it say B250K or A250K?

Here's some helpful advice for using Mouser:
Don't "shop" on the website. They carry tens of thousands of items, and the site is not exactly set up for browsing. What it's really good for is when you already KNOW the stock numbers, and you're ready to place an order.
On the other hand, the Mouser catalog is great for browsing. It's categorized, and there's pictures of each type of component. For example, browse to the "passive components" chapter and you'll see a section for potentiometers. Open that section, and you'll see a section for Alpha components. Open that section, and you'll see a list of pages. Start at the first page in the list until you find the section for 24mm pots. Look for the picture of the pot you want, and then find it in the list with the value and taper you need. The part number is a web link to the corresponding page on the web site.
The catalog file is huge - 240MB and growing - but it's worth a download every couple of months if you're going to be ordering parts on a regular basis.

Aside from making sure you have the correct pot specifications, don't overlook possibility of capacitor related wire grounding out on shielding. It happened to after installing new electronics in a Les Paul. It played but sounded like shit and no power. Then after the finding and fixing the capacitor short to ground it woke up the gorrilla.

It may be the pot type, pot value, or cap value.
If you have the amount of of trebble removal you want when you turn the pot completely down, then you have the proper pot value. If its too muffeled, then use a lesser value or add a resistor in series with the cap.
If its a matter of going from completely off to completely muffeled quickly when you turn the pot down then you have a pot taper issue. pots have different tapers depending on their application. The overall resistance may be fine.. 250K, 300K, 500K amd 1Meg are the most common used in guitars with passive pickups.
If you look at the value stamped on the pot can it should have an A, B, C, or G
You can read up on audio taper types here.
Chances are what you have in the tone circuit is a linear pot which sounds abrupt when you turn it down. What is used in most guitar circuits are the logarithmic/audio tapered pots. These sound more gradual to the ear as you turn them down. The pot value for the pickup type is important too. 250K are usually used for fender single coil circuits, 300K for P90 single coils, and 500K for most Humbuckers. You can of course use different pots with different pickups but the tape may not match whats considered the normal tonal changes that occur whan the pots are turned.
