I had to take my new guitar back to the shop where I purchased it.
The bridge started lifting up on it, and I was getting awful buzzing. Weird buzzing... it would start off barely audible, and get louder as I played longer. Then I put the guitar away for awhile and would come back, and it would start all over. About a 30 minute cycle.
I thought it was my fault at first, being a returning player with relatively weak fingers. Poor fretting technique or something. I re-strung the guitar, played a bit with truss rod adjustment, tried all sorts of things while I also built up my finger strength and technique. But nope, I start really investigating and I see a hint of an air gap on the back side of the bridge, and can slide a piece of paper about 1/4" deep underneath it, between the bridge and the face.
Lifetime warranty on the guitar... I'm waiting to hear if the shop I bought it at will be repairing it, or getting me a new guitar.
It's a fairly complicated bridge for a classical guitar. There is a piezo pickup under the saddle, and a pair of metallic rivet-looking studs that assist in holding the bridge down against the face along with the typical glue. Not certain what those metal studs are... bolts, rivets, or what. Bolts strike me as too susceptible to loosening, rivets as too permanent and hard to service. It's a unique construction technique that I only see on Godin/LaPatrie guitars.
But, I'm without my lovely new classical guitar, now.
