OK, but do you think there is definite niche for each variation, or would one type cover all.
Pass. On the whole at least.
You'd have to as a customer that has tried most to all of them. And then you'd get a biased answer because they likely wouldnt have bothered doing that if they werent rather enthuiastic about the different characters of different pickups/guitar sounds.
And anyone that hasnt is obviously someone that is satisfied with a close-enough sound to whatever they wanted to achieve.
So basically it depends on the guitarist in question.
Personally, I use:
Warpig
Ceramic WP
MM
Cold Sweat
Uber 23k double screw pole MM
Irish tours
Uber trilogies
Plus a bunch of other pickups.
And I dont listen to Ozzy, sabbath, or malmsteen and I dont even know what the cold sweat is named after (I do listen to Rory Gallagher though). I went for those to achieve a sound in my head derived from all the music I listen to and tones I've heard and used in person.
I do appreciate the differences between each one and go for the guitars they're in based on the character of the tone, but recognise that for example there are 4 very powerfull bridge metal buckers there and many poeple would say they do the same job.
Thats kind of true. But to me its just no fun. Theres enough differences in the tones for me see a different character in each, and I like that.
I suppose what I'm trying to say is if youre satisfied with one sound that approximates many, then fine. If you want many specific sounds, also fine.
