I'm auditioning a couple of Phil Jones Flightcase amps for a review, and they both sound amazing with just the Full Circle running straight into them. The preamps sound fantastic, and I really wouldn't want to change anything about that sound. On the gig last night, I did find in a couple of places that I missed the option of blending in a mic signal, though. The amp does have an FX send and return on it, but no "blend" control. What I was wondering is if it would be possible to use this loop in the circuit to try to insert a mic signal with some sort of volume control so I could see how the amp would sound with a blended signal. Is this possible, and if so, what kind of cables would I need? I could try it with something as simple as a canon plug into a K&K wallet sized pre, and/or also with dedicated studio type pres.
