This guitar is gorgeous, plays well, sounds awesome and is versatile. But it has a fatal flaw. I've owned two of these and both have a buzzing that I think comes from the bridge pins on the body. It's not the bridge as it's a solid bridge. It's very noticable fretting a full 6 string harmonic strum rather strongly. It comes and goes, but I can't play for 10 minutes before I can hear the built in fuzz box on my notes and chords.
I'm not sure it can be fixed without radical surgery. Odd thing is, my White Falcon has the same bridge base/pin setup and doesn't have the problem at all. But it doesn't have the TV Jones pickups or the tonal options of this Penguin. If I can find a really good repair shop to fix this up, I'd gladly get it fixed it the cost wasn't absurd, because I do really love this guitar. It's a work of art.
Update: I haven't investigated this but I was noticing when loosening the truss rod on another guitar that a somewhat similar buzz started. So I need to slot a little time to see if a slight tightening of the rod on the Gretsch solves the problem.
