Really great to know about the Felix! I never really thought about all of the challenges associated with the pickup and mic combination, but that's mainly because I've seen people use blender systems that are all integrated. Good to know.
I actually do use a Tonebone PZPre, and am glad to know you used use it with Punch Brothers! I agree it is a great preamp. I usually have to kick in the lowpass filter and the eq is pretty nice. The boost is pretty good too. For what I'm doing/using right now, it works really well. Depending on the gig, I'll either just take a line out of the Tonebone into a PA, or if I'm doing a solo gig then I run it into an AER Alpha amp.
Thanks for all of the information!!
