I just ordered a Sans Amp RBI as an upgrade from my Bass Driver DI. (I have not recieved it yet.) I've been running the DI through a bi amped GK 700 RB on the front end. Is there an optimum way to patch the RBI, other than RBI out to GK effects return? I want to keep the Bi Amp functionality of the GK. The tone of the GK preamp is very good, but the Sans Amp is perfect.
