I have a Rio Grande BBQ in the bridge of my PRS Singlecut and am quite happy with it.
This pickup has a lot of midrange, some compare it to Crawler. Personally I have never heard the Crawler........
It does tend to get a little Barky.........but I kinda like that.........
But to be honest, you can plug in a almost anything into the budda and it will sound awesome...........
I've tried a lot, JBs, Custom, Holy Diver, PRS #7, Dimarzio 36th, BBQ etc. and they all sounded good, some more my taste then others, but the amp just makes everything sound nice!!
So far the ones I like best are the HD, Dimarzio 36th and the BBQ.
Thinking about getting either a A-Bomb or a Suhr Doug Aldrich set for my Tokai LP Goldtop
