I think Nailbombs are for you, donŽt know if ceramic or alnico are better for you. Depens on how you like your eq to be in detail. My guess would be though that youŽd fare better with alnico.
With the nailbomb you have a rich Pu that is has agressive (dirty) rock / metal mids, without going overboard. Has a bit of a 90s feel to it and has a vintage rock character somewhere in its tone. Generally, this things has character. Also it is very versatile, so depending on your gear, playing and PU height you can get a wide variety of tones.
I do think that it is the closest BKP to the crunchlab, which is a great PU, but...well I think of it like: There is a CL we get and then thereŽs a CL Petrucci gets...and this is it.
