I have a ‘matching’ GK main rig - 1001RB into a Neo 4x10, and also use a GK MB800 ( or occasionally my lovely old GK 800RB ) into a gen 1 Barefaced Compact. ( I also have been known to use my old Loud Inc 4x10 on occasion, which is probably the best ‘bang for the buck’ I’ve owned.)
Doing theatre shows I did want something that looks okay as well as sounding good, and for me the all GK pairing fits the bill just fine. Although a long time GK user, I’m still open to change though - if finances allowed I’d probably go down the Aguilar route as all the ones I’ve heard sound pretty damned good. A BF 4x10 (or two 2x10’s) would also tempt me, again if finances / gigs improve.
