Prolly when I was overseas at the time it made it's debut... (yes.... that long ago)
I can say this I did though have 2 SH-4's -JB and didn't cut the mustard both times. Ofcourse I didn't have these insane amps at the time, but I can say although diffent mags, that the SH4 vs. the 5 sound similar with the Alnico 5 JB having an more high's & separation in the notes and the ceramic SH-5 with more smear & growl.
Anyway look for the little white sticker w/initials
