Robert's right....again! :smack:

I'd consider the PG's...they're alnico 2 too.
Guitars with just a volume control and no tone controls are brighter too. So if you want the Alnico 2 Pros, you could install NO LOAD tone pots. NO LOAD tone pots will remove themselves from the circuit when the tone control is turned to "10"...the guitar will sound brighter, as if no tone control was present.
I've started putting NO LOAD tone pots in all of my guitars.
Another option would be the 50's mod. That's real easy. Most Gibson's are wired with the tone control connected to the same terminal of the volume pot that the pickups are connected to. If you move that connection for the tone pot to the middle terminal of the volume control instead, the guitar will sound a little brighter, especially when you turn down the volume control.
I have also heard of people using 1Meg pots...1000K. Those supposedly make a guitar sound a little brighter too.
Never tried it tho.
None of these methods add highs or treble. All they do is help you retain the highs that are already present in your guitar but which are bled off to ground inadvertantly.
