Honestly, there's enough "boutique" pickup winders here in the US that charge insane prices for their plastic and wire, we certainly don't need another one coming in with grandiose terms like scatterwinding and magnet-seasoning. It's all BS once you add the drums, anyhow.
Bill Lawrence, Larry DiMarzio, and Seymour Duncan are my kind of guys. Yeah, they're not the cheapest, but the quality is more consistent than the boutiques and the sound can't be matched for another $200.
OK I think good pickups are worth it.
When you go and see (insert favourite stadium filling act) do you really think their pickups come straight off the production line? I really doubt it you know.
(with the exchange rate being what it is at the moment perhaps now isn't a good time to be importing things from the UK I'll have to concede that point)
as for the 'doesn't make a difference' arguement... Would you build a guitar out of plywood and hand it on using the same line?
Any way here in the UK its £140 for SDs or DiMarzio and £180 for BKs so it aint much more.
