Diabolical, im using a Gibson Les Paul Studio.
And the tubes and speakers have actually been replaced, its old but it works like new.
Those speakers can blast man, but yeah.
I looked up peavey mace, and sure enough...thats exactly what it is.
So its a good amp im assuming? :p

Oh, the pickups are stock, whatever came with the gibson les paul studio is what i have

You assumed right. From what I know about them, they are becoming quite difficult to find and are sure to become a collector's item within a few years, make sure you hang on to it!

Strange man, from what you've mentioned everything looks stacked in your favor to getting good pinch harmonics. I'd say try to dial in some mids from the amp's eq, try a compression pedal and then crank 'er up! If you can't get them - analizing your technique might be the best thing to do.
