Hiya
I've used the covered Abraxis bridge pickup a bit.
I'd discribe it as follows.
Clean:
When clean the Abraxis bridge has a character I would discribe as bright, strong, clear and solid.
It has a very even responce across the frequencies with a notable drop off at both the extreme low frequecies and extreame highs. so no boom and no icepick. the most noticable characteristic of this pickup clean is it almost sounds as if there is a gentle touch of compression to the tone. Its very even but still has some character to the mids that does grab attention. I have heard this pickup be used clean sucessfully for Jazz, Rock and Roll, Latin and modern pop ballads.
Distorted:
This is where this pickup really shines. The tone here is exactly what you'd expect. the lack of boom and icepick frequencies with the compressed sound gives a strong clear sound with a slight classic feel. Even underneath heavy gain settings every note is perfectly defined. Incredible for guitar solos. Distorted rhythm work sounds precise, solid yet charactered. Takes well to the full range of gain settings. At the gently pushed end the compressed character gives a uniquely solid and even tone whilst at high gain it still maintains clarity but still with slightly classic character. Usable for modern (post 50's) blues, clasic rock, Pop and a suprizingly beautiful Metal pickup.
Its probably too ballsy and charactered for extreme shred (through a Marshall at any rate). try a Nailbomb.
Also the lack of bottom and slight compression leaves it not the best choice for jazz dispite being PAF charactetered. (Stormy Mondays, PGs and Mules a better choice here)
As an overview this is a strong pickup with a PAF character that cuts through a mix like a hot knife through butter and absolutely demands an audiences attention. If you want to sit gently in the back of the mix this pickup is going to be a bit too much. if on the other hand you want to turn heads when you kick in with your strong yet classic tone this is absolutely the pickup for you.... Its Heroic yet classy and classic.
Well thats what I think anyway.
