Line 6 US JTV-89 - Acoustic mode now sounds like fret buzz

[nd_mustang]

The crazy thing is on the mags - no fret buzz - so I'm assuming it's with the piezo pickups. It's especially noticeable on the low E/A/D strings, but can be heard on G/B/E slightly as well. Anything I should check first before replacing the piezos? Where do I get replacement piezos if that's needed?

Hey nd_mustang,
When you say that the acoustic mode "now" sounds like fret buzz, was it working normal previously? And did anything change in your setup between then and now? (string gage or manufacturer, neck or bridge setup, etc.)
