I own Carlos' Gibson L-6S from the Borbolletta period. I bought it at Leo's Music in Oakland, for, wait for it.... $400.00 in 1983! Its beautiful with blue butterfly 🦋 wings covering it (Borbolletta) in Spanish, and sounds incredible. A wonderful piece of music 🎶 history. I am so blessed, I love that album and guitar 🎸 sound.
