The RRB is my post-dirt lead boost. Interestingly enough, I run a Klon pre-dirt in my chain. I find they are very complimentary, but also quite unique (this may be obvious, but I find it interesting -- they were not intended to be similar whatsoever).
What I find to be fantastic with the RRB and a Strat/Deluxe rig is the hair added by the RRB as a boost. My rig almost requires this edge to really throw the tone into the mix and give it an added girth. The amount of boost the RRB can provide is also quite impressive, and for some, might be too dramatic. For what I do (which is really not much ), the RRB is a pleasing, aggressive boost with enough low-mid presence to satisfy my tastes.
How do you run your RRB?
Cheers.
