Thanks for the response guys.

It was actually a build diary on an ES-5V that raised my concerns about using one as an acoustic.

Having said that, tapping the top sounds ok. It would probably sound fine if all you want is to practice while the kids sleep in the next room.
I'd like to avoid pulling apart the body if I can help it. Also, would it be possible to get a GR-1SF with only the F holes and neck pocket routed? I'm not concerned with time frames at this point. I'll need time to come up with the money and talk things over with my other half
