they sound raw and brutal through a jcm800, but clean up alright.
i wouldn't mess around fitting them - loads of output!!
edit: they can be unsubtle and muddy too though, Feline describes them as gruff, which is true. but if you get them setup right they are great.. i have the bridge side pole pieces raised up 1-2mm more than the neck side. theres a sweet spot where the tone is still raw, but the muddiness disappears.
