Preamp to blend piezo and mag pups?

[pdeon99]

I want to add & blend a magnetic pickup with the piezo pickup in my Zeta Crossover (4 string 35”). I think the best approach is to replace the existing electronics with an on-board preamp that takes in both types of raw (unbuffered) pickup outputs, and provides suitable tone adjustment. The magnetic pups I'm choosing between will have either 20K or 2.4K resistance. The piezo is high impedance, naturally.

Any recommendations on a preamp that does this? So far, I found a Bartolini MPB1-918.

The Bartolini you mentioned is, I think, the same that is in my Surine Regency. It's very nice on its own IMO. I actually removed the three-band Bartolini EQ that was in my bass, because I ran it flat the whole time.
I'd recommend that one.
