I LOVE my Corona Guild. I was lucky enough to find it on Ebay back in 2005. It had a small crack on the rear bout that my luthier filled in for me (no cleat needed - it was that small), and I wound up getting it for $880. Talk about a buy! Even through the subsequent Jersey winters and summers, I've had no issue with the finish cracking. I think I got a good one.
I have since added Grover 18:1 locking tuners, brass endpins with abalone, tortoise shell truss rod cover, a K&K Trinity Western pickup, and Hans Moust helped me find a matching piece of pick guard material that I added above the soundhole to make it look my John Denver's good 'ol dual pickguard F50R from the good 'ol days. Came with a G&G case, and I just love it.
Every time I open the case....AH....!!!!!
