Re: DiMarzio/IBZ Pickups?
I don't know what you guys are complaining about.
I have a Japanese market RG2770FMTB with these pups. For my use, which runs the gamut from Louisiana blues to screaming leads a la Vai, they're perfectly adequate. I've done studio work with the guitar, played live gigs with it, etc... never heard a complaint yet from my producers, sound managers, and bandmates. The DM/IBZ pups work extremely well with either my rack-mounted tube processor (which has triple 12AX7's in an early 90's Digitech TwinTube GFX1) or my more portable Line6 Spider II 120. I can dial in just about any sound I need with either rig.
If you find them weak, I'd (A) look into learning how to better employ the presets/sounds in your outboard gear, or (B) take a good look at what processing you're utilizing to generate your sound. In my not-so-humble opinion, nine times out of ten, I'd bet its a guitarist's gear, not the pickups in the guitar, that limits a guitar's sonic capabilities.
