A while back LD had a big group buy and I ended up with pretty much every library they sell, I think maybe 20 or so in all. Of them, the only ones I've ever actually used in a song are Ripper Amped, '73 Strat and Dirt Bass.
The acoustics just weren't quite as good as others I already had (although the nylons are acceptable). I tried using the mandolin on more than one occasion, but it was too harsh and "plunky"-sounding. I may revisit some of the electrics, as I have a more extensive amp and speaker sims now than I did back then.
