......from what I remember.........
The V7 was quite a bright pick-up but I only ever remember it being in the
neck position.
The V8 was again quite a bright pick-up.
The IBZ/USA were designed by ibanez and DiMarzio and made in the DiMarzio factory. The F2 was quite a mid rangey pup. I used to have some in the bridges of 770DX's. I'd say it was more of a
bridge pup and that the the F2 had the higher output.
Why don't you find yourself a nice PAF Pro
Hope this helps
