Instruments are like kids. I can't have a favorite because it would be insulting to the others. Although I have high hopes for the guitar that Collings is making for me now. A 000 2H 12 fret slothead with a few bells and whistles on it. I should have it in about 6 to 8 weeks.I hope to never sell my 1967 D-18. I bought it in 1969 and it's a great old guitar. Really trustworthy. If the house was on fire it's most likely the one I would grab. My prewar 1999 OM-28V could be replaced. Same with my Lowden 12 string. They don't have the emotional investment that the D-18 has for me.
