I like this pickup, it's insane, but it's not really working well in my RGT. I'm going to try one last pickup swap before giving up on this guitar (this will be the 4th attempt at finding a match!)
As for trades - Preferably other DiMarzios as it's a brand I've not yet explored quite as fully as Seymour Duncan, but I'll happily take a Duncan if there's one that tickles my fancy.
Hot (but not insane) and tight are the criteria really. Something that handles low tunings well. F/Trem-spaced.
Practically anything on their 'high power' page - High Power | DiMarzio
As for Seymour Duncans, I'd be happy with the following;
Any of the new fancy flavour-of-the-month models (Nazgul, Pegasus etc)
Maybe even a Dimebucker
What are the wings on that guitar?
