The leg-spinner took 763 wickets for Essex in 325 first-class matches between 1961 and 1975.
He also played first-class cricket for Glamorgan and took more than 1,000 wickets during his career.
Writing on X, formerly known as Twitter, his son Nick Hobbs said on Sunday: 'Today I said goodbye to my best mate. Rest in peace, my mate.'
In a 2020 interview with BBC Essex Sport, Hobbs stated: I take great pleasure in having taken over 1,000 wickets as a leg spinner. It is unlikely that this feat will ever be repeated due to the reduction of county cricket matches.
"I was very very lucky in my career".
Hobbs played his first club cricket at Chadwell Heath in East London. He then moved to nearby Chingford at the age of 17, where he took over 100 wickets on what he described as 'fairly dodgy pitches'.
