    Yes, you can add a BnB to a Dr Phybes. And what, specifically please, do want to know about phase inversion?

    Here is a guide written by Wilkie1 and Tonmann which contains everything you need to know about Phase inversion, when it matters and how to deal with it. Phase Follies – A Phase Inversion Guide

    In short the Dr. Phybes inverts the phase so if you are using it in a parallel situation like the Buff N Blend you may easily correct the phase by placing a small 1″ x 1″ Stage 3 in series with the Phase 90 before it hits the BNB.

    The Stage 3 is a clean Gain Stage that is extremely transparent when using our J113 FETs.
