one of the best basses i've ever played

By the early 1980s Lesh had moved to a Modulus 6 string. The Modulus story also sports some Grateful Dead / Alembic links. After attending a Grateful Dead concert in 1974 – and being impressed by Lesh’s Alembic basses – Geoff Gould started experimenting with lighter and stronger materials for guitar construction. Gould had a background in the aerospace industry and used this experience when developing hollow carbon fibre necks. In 1977 a collaborative project resulted in Alembic launching a bass model that featured one of Gould’s graphite necks. Gould went on to form Modulus guitars and now builds instruments under his own name.
