Yes, the D42 sounds like it's made of better material than the O.S.. The top really resonates on the D42. It's louder and deeper than the O.S., also.
The luthier quoted me a price I thought was too high. So I backed down from taking it to him.
I'd rather put that money into a good 50/60 watt amp.
I went ahead and read up on how to sand off a saddle to lower the action.
After removing the old strings, I removed the saddle carefully with some small pliers. It came out with a bit of resistance. Using 120 grit paper (best quality), the saddle was squarely sanded down 1/32". I took measurements with electronic calipers and recorded the results so I'd know where I was at. Next time, 100 grit or heavier. (BTW, I marked the front side so I would be able to put it back in the same way.)
The OEM saddle looks like some kind of plastic, but it is very hard and took longer than I thought to sand off 1/32". (I tried to buy a bone saddle, but could not find one locally.)
EDIT: Forgot to add that I polished the frets with fine steel wool, cleaned the fret board and made (2) more 1/8th turns to tighten the truss rod while the strings were off.
Ended up with a total of 3/4ths of a turn on the rod.
The saddle was then replaced and new ELIXIR Polyweb strings (10's) installed. The guitar got a tune up and sounds much better and is definitely more playable than when first purchased.
I did not achieve everything I set out to do, but it's better. I figure it will take me a few months to a year to really "break" the guitar in and get to know it. So, I may make some more tweaks and a bone saddle (have to order it) next string change.
I also added a strap pin under the neck. I don't see using the headstock to support an acoustic. The neck already has enough stress without supporting the guitar and the player's arm.
More some other time.....
