John McVie's 1976 Alembic Custom Bass
McVie most famously played this bass on "The Chain" from Fleetwood Mac's album Rumours (1977) and during the subsequent tour.
Alembic co-founder Susan Wickersham explains that the instrument was crafted for McVie in 1976, and that due to its stainless steel fretboard: "Rather than call it a fretless bass, I preferred the term 'continuously fretted' bass."
