EMG ABC Blend Pot - Suitable as Mag / Piezo Buffer Blend?

I kind of have the same question, though I'm mostly using the Graphtech Ghost stuff (with their balancing preamp) in most of my current projects.
 
I have an ABC control and use it w magnetic pickups only. I like it a lot, but with a published input Z of only 200K ohms, I don't think it would work well to buffer piezo elements, which really want to see 1Meg input impedances.

YMMV...

I see, thanks!

I am pretty sold on the EMG BTC system (I like you can set the treble filter curve to affect high high mids only). I just need some sort of buffer pan for the piezo and magnetic pickup that would work with the EMG pre setup.

Alternatively I could just remove the Piezo, it's just that the body I'm getting already has one installed under the bridge in a small route. I guess I could fill it in with some wood putty as it will be covered by the bridge regardless.
