Hi Dave,
many thanks for your info on the Greg Lake 8string.
To my knowledge Greg Lake had two Alembic eight strings with a very similar design.
The first one, buildt around 1976, was in longer posession of Greg Lake and is currently on display at the London Hard Rock Cafe. This particular one is shown in the Bass Book of Tony Bacon on page 41.
The mentioned 8string Greg talked about which he had sold to John was of a very similar design and this particular one had pirate motifs on the fingerboard. This bass was auctioned this year in the Sothebys auction for GBP 10800
(see auction catalogue page 89).
Many greetings
Oliver (Spyderman)
