No idea myself.
Sketchy info.
Apparently they had summit to do with head guy from Epi Elitist (apparently Elitist was never 'legally' imported into UK,maybe Europe even,not an expert).
Anyway, he made these and Gibson thought em too good? So said 'STOP'
Hence, made no more.
Only found cpl. guys/reviews on H-C who really rate em (and they are Gibson LP owners too).
