I still think the RG7421 / RG7621 are excellent 7 stringers! I fitted my RG7421 with Dimarzio Blazes. sounded awesome but too bad as of now, I have to recoil both my neck and bridge cos the coils broke. dang.
still, all I wanna say is, fixed bridge ERGs ftw!
Yeah I enjoy playing the 7421, i still have the stock pickups on. The V7 and 8 pickups are really quite cool, they're tight and articulate unlike those pickups on the newer models. I had to change those on the RGA8 first time i heard them, muddy and all over the place - i dreaded playing it till the pickups were swapped. The Aftermaths are superb!
And yes to fixed bridges!
