I'm looking to know what the specs are on the Infinity 4 bridge pickup. By specs I am referring to a similar style to what Dimarzio uses in terms of the frequency scale - highs, mids, and lows as well as high or medium output. I am wanting to know these specs so that I have an idea of where to go from when choosing a pickup for my RG 321 which has the stock INF 4 in the bridge. I like the output and frequencies that it has, but would like a bit more clarity and less "fizz" (for search of a better word). Thanks.
