Larry Coryell's acoustic LPs are some of my favorites; his 1st duet with Phillip Catherine, "Twin House" on Elektra is not very hard to find and one of the most inventive and virtuosic acoustic guitar records I know. "Standing Ovation" is another excellent solo acoustic LP. He has a live at Montreaux Jazz Fest I think called "European Impressions" that's also quite excellent.
Bert Jansch and John Renbourne, the original guitarists for the UK band Pentangle have a great duet LP and loads of fantastic solo LPs.
Their mentor and one of the finest guitarists ever was Davey (sometimes spelled as "Davy") Graham. His "Complete Guitarist" LP for Kicking Mule is astounding solo acoustic. UK pressings of Kicking Mule always sound noticably better.
