Although tone is more of a personal issue and at the end of the day it comes down to what you like, what you have got used to hear or, maybe, what you would like to achieve, these humbuckers definitely provide the basic sound of rock and roll.
As the sound of rock music changed through the years from one continent to another and as it is kind of hard to write about something that you should rather hear, I will bring it down to only a few remarks.
These humbuckers mounted in a Gibson Les Paul and sent without any effects through a Marshall tube amplifier (some of the older ones are recommended) deliver the smooth and crunchy sounds that I personally like and end up to dial in mostly every time.
In terms of responsiveness these humbuckers are way ahead of any other tried before, so all the sound lies in your hands and responds to your choice of expression. If you turn down the volume you get clean tones even at higher gain amp setting and as you turn the knob up the dirt starts to show topping in a beautiful warm crunch. The humbuckers are of medium output comparable with the Seymour Duncan Seth Lover model.
The fact that they are not wax potted does affect the sound in a positive way and nowadays it is not an issue anymore as we do not get the chance to play that loud.
