I'm the original owner of a 1991 Taylor 515 Ltd. Jumbo. It's a beautiful figured spruce top over highly figured mahogany back and sides. Body has a venetian cutaway and Taylor pickguiard, and the mahogany/ebony neck has an 1 11/16" nut. About 4-5 years after I got my 515, Taylor introduced the Leo Kottke 6-string (LKSM -6) guitar. The LKSM-6 has the same body size, body and neck woods and venetian cutaway as my guitar. The only differences are no pickguard or fretboard dots on the fretboard of the LKSM-6. So I have always wondered if Taylor maybe built 515 Ltd. as a market test for the LKSM-6? (The LKSM-12 was first announced in 1990.) My 515 sounds clear, warm and big! It excels at altered tunings, and flatpicks and fingerpiks equally well. I think the early1990s Taylor Ltd. guitars got some of the special sauce!
