Have you seen the Tillman preamp or it's variations? It can be used with a piezo.

Maybe there's a reason for that.

EDIT: why do I suggest an "old boring" Op Amp, instead of a "new exciting" one?
Well, it depends on goals.

If you already built a dozen Mic preamps and are bored stiff with them, ok, start plugging new chips in the old circuits.
Personally I'd try to design new circuits, but hey, that's me

But as you seem to need a working Preamp to actually be used to make Music, well, I'd try to avoid (unnecessary) surprises and build a robust well tried circuit.

Otherwise, you are walking a minefield.
As in: did you notice the MCP6022 is designed for PSUs of 2.5 to 5.5 V (single rail)?
With an absolute max rail of 7V?
Meaning that 9V battery would probably destroy it.
Not nice to find that after you built it
Well spotted, thank you.

yes there are odd "standard" V supply for some of these but 12 V(total) is common - you do have to check since 6-7 V breakdown processes are used for "5V" single supply CMOS op amps and a few rated even lower for 1-2 cell battery operation
