If the string is catching at the nut, you will probably find a burr that is preventing the string from slipping by when you tune. A careful pass with a file should remove it. If you were here in town, we'd be happy to take care of this for you.  
 
But then I just reread everything in this thread and you mentioned using a larger diameter string in the Tribute than the 10's it was originally setup with. As Dave suggested, you might need to have the nut slots enlarged since running a thicker string through the original slot can bind up even without a burr.

Thanks Mica.
 
I took the Tribute by Dick Dubois today and he fixed it for me while I waited (about 20 minutes)
 
I highly recommend his work for anyone in the central Texas area.

My Peterson VSF showed up this afternoon. I set the intonation on my Series I. The A, and G were way out but the others were almost dead on. Will try it at practice tonight and see how it goes.
 
Does anyone know how long the 3 AA will last? One less thing to plug in.
 
Sam, this is a really cool guitar. Thank you again for selling it to me.

My Peterson's batteries last a long time.  Of course, I don't leave it on the whole time I'm playing.  I use the tuner out on my volume pedal and turn the Peterson on to tune and then off.  I probably change batteries once or twice a year, at most.  The other guitar in my band keeps his on top of his amp in the signal path, plugs it in and leaves it always on.
