Re: effects of slanted pickup
kramer slants their humbuckers, EVH style. bass side away from the bridge.
It was done that way because EVH liked the PAF sound but couldn't originally fit it in a Strat Body to align the poles over the strings...so he angled (slanted) it to fit properly...or at least that is what I read. Now EVH did use a Charvel...but at some point in time he went to the Kramer Factory in New Jersey and assembled the Kramer Banana Heads to be the Guitar he would endorse.
When Kramer got EVH's endorsement the Guitar was fashioned and supposed to be his 5150 Guitar...but the reality is that the Barettas are much different then what his 5150 Guitars would be (alder I think with maple non angle Hockey necks)..but the result of Kramer trying to make a Guitar that would suit a Guitar God.....resulted in a fantastic guitar that is now legendary...which is the vintage Kramer Baretta and why they did the RI.
We also know that EVH is and endorsement whore (lol) and only really supports himself and what he likes. The CC was supposed to be his Seymour Duncan pup...and he flaked on endorsing it as well. The end result after him going through Kramer, Ernie Ball, Peavey, and now his $25K Fender Frankensh!t. I have heard from many that it is a horrible guitar and that it just has his signature markings and a remake of the original...think about it he finally got people to pay $25K for a Guitar for him or to be like him.
The reality is the Warren DeMartini signature Charvels will probably be some of the nicest new Guitars available for shredders....or a Jackson V will aways do the trick too.
People know basically the following Guitars the best and you can almost tell the culture just by what guitars they released for Guitar Hero.
You have
Gibson LP & Explorer
Fender Strat
Kramer Barettas.
I love ESP and Charvel/Jackson too...but they didn't get a spot on one of the most popular games ever (or at least I haven't seen one).
You don't need an "F" spaced tremolo pup for a slant design...it was never intended to be that way. In fact even people with the standard pup alignment don't go with Trem Buckers.
