Re: Dimarzio virtual vintage solo pro dp 414
They don't make it any more. The updated version is the Virtual Solo. It's a bit smoother and less of the "wah" sound than the Virtual Solo Pro. I like them both a lot, but it depends on what you want. If your guitar can get a bit bright, the Virtual Solo. If your guitar needs a little edge, then the Virtual Solo Pro.
I have a Virtual Solo and Area 58 in one of my strats and it's a fantastic combo. Another strat, which is probably my favorite, has a Virtual Vintage Heavy Blues II and Virtual Vintage heavy Blues in the neck. They have alnico 2 magnets so they're very warm and have a pronounced "wah" sound. The pick attack is like a P90, but the tone is like a humbucker in the neck. I recorded something with the neck pickup and people thought it was a Les Paul. I could probably find that recording laying around somewhere.
