Paul Rivera's Fender Princeton Mod Link

If you read my post on Steve Lukather's Rivera modified Princeton amp, here's a link I recently discovered that provides instructions and schematics to get your Fender Princeton souped up to Lukather's specs:

Bear in mind that I make no claim as to the accuracy or safety of the amp mod information on that site. 

And make sure you know what you're doing before opening up any amp and poking around in there -- these kinds of mods are best left to a qualified technician.
