I hope this helps, but I have 3 guitars... One 7-string, and two 8-strings, all with GK-2A's on them. For me they track just as well as on all my 6-string guitars, and I have 6 equiped guitars in total. Here are some photos of the GK-2A mounted guitars: Evolutions in the 7, BKP Cold Sweats in the RGA8-BK, and soon to have Lace Aluma's in the RGA8-QM this month. Thanks Lace... Cheers. Feast: Knights of the round table... BKP Cold Sewats (Matched Set): Dimarzio Evolution (Bridge) | Stock (Neck): Lace Alumas [Chrome] X-Bar (Neck) | Deathbar (Bridge) in 2 weeks: In two weeks I'll compare the 2 8's with the new pickups and the old stock Ibanez . I'll show the differences between the BKP Cold Sweats, Aluma X-Bar (Neck) | Deathbar (Bridge) and of course the stock Ibanez. low Z actives.
