Tried a search with no results. I wondered if anybody has put a tremelo system in their ZM? If so, what system did you use. Not sure I want to do it, but curious. Steve
I wouldn't want to route out the body of a ZM to accommodate a PRS style vibrato. A Bigsby might be much more doable, and maybe cooler.
A little googling led me to the Stetsbar, which seems to be a non-destructive, but expensive, way to put a trem in place of a wraparound bridge: https://stetsbar.myshopify.com/products/chrome-stetsbar-for-wrap-around-bridge But at that point you're almost halfway to an SE Custom 22 or 24 with trem (maybe less, used)...
