i had got an HD set in a thick all-mahogany SG styled guitar, the USM hornet, and they never really caught me. i decided to give the HDs another chance, though, and got ANOTHER set (i'll sell my first set very soon, so stay tuned... :)) for a different guitar, an ibanez S320 (much thinner mahogany body, maple neck... very middy).
these are just preliminar impressions because i had not much time to play it yet, but the result is at least interesting... this new combo sounds COMPLETELY different. much much better, i'd add! the base HD tone is of course there, but it suits much much better the acoustic character of the S, while with the hornet i had the impression to suffocate the guitar's potential with the wrong pickup choice.
the bridge HD now has got a very singing tone on high strings while retaining its howling low and mid midrange on rhythms... pinch harmonics are much easier to get. palm muting isn't too powerful but sounds quite sinister and aggressive... it's very clean compared with other contemporary BKPs (all of them, actually...), but can still sound very nasty if properly driven.
the neck HD still doesn't convince me too much, but i must give it a full test to express a real opinion... the "strange" thing is that its tone doesn't change much when parallel connected... it gets just brighter (and a bit thinner, of course)...
