Hi Phil,
I saw the Timeberline nut advertised as 1.75 at a couple retail websites:
https://www.elderly.com/products/tim...itar-with-case This model is the TG60HGc, not the TG20 (don't know if that makes a difference in the nut width, or if they are both the same).
http://www.harpguitarmusic.com/listi...ine-models.htm Gregg Miner's website actually lists the nut at 44.5mm, which is a hair over 1.75 inches.
The 44mm nut doesn't rule out a Timberline for me completely, but it lessens the appeal. 1.75in (44.5mm) is the narrowest I'm comfortable with on complex fingerstyle tunes. My ring finger tip flares out a bit and it's pretty hard to fit it cleanly on narrower nut widths.
Thanks again for your input,
Matt
