With 300k pots the humbucker will be less bright, the singles a tad less bright.
I meant bright, compared to something like the Crawler and Abraxas, but the topend of the VHII is not shrill. There's just more presence, but the VHII performs well in strats and you can really steer the VHII with your pickingattack. Dig in and it screams.
