Well when i got it back...to me, it sounded and played as good as any of those guitars. (Although I did really like one of the Martins.) The difference the action, bridge, etc adjustments made is just unbelievable.
Just goes to show the value of a setup by an excellent tech/luthier.
Not in the same price range as you've been looking at, but I have a similar story. About 3 years ago I decided to start playing again after 10 years off. So, I took my 30 year old Yamaha FG160 into the guitar tech at GC to see what it would cost to get into shape. He said about $170 (new saddle, neck adjustment, etc...). I thought "wow" I only paid $150 for the guitar to begin with. Maybe I should just buy a new one. So I played everything in the store from new Yamahas up to Breedlove, Martins and Taylors. The only ones that "fit" my hand were the Taylors, but I didn't love their sound.
I was still debating what to do, when the tech asked a passing salesman if he wished he still had the first guitar he ever owned. The "yes" answer pushed me into paying for the repairs. Got the Yamaha back and I couldn't believe it was the same guitar. It never played so well in its life and I wouldn't trade the sound for any of those higher end guitars.
Enjoy your Guild!
