Have used the GFX-8 for 5 years before I upgraded to the new G9.2tt.
IMO is a gd multi-effect overall, u can get decent tones out of it and its very gig-worthy with its metal casing and all. I did a few recordings out of it and also used it for alot of gigs.
The cons I would say is that if u r really into high-gain, max distortion only drive then it doesn't deliver that great. Also the Wah's sweep is not as much as u would get from a 535Q.
But all in all its a value for money multi-efx, however its all up to u as tone is very subjective.
However a plus thing is that its MIJ, hehz... :wink:
