Hi, guys. Been looking on the web and found some contradictory info regarding the year these amps were made. Mine has serial number 521504. Made in Japan.
Can anyone help me dating it?.
Thanks in advance

Congratulations on the new amp - I really love my JC77 (roland’s vibrolux in some ways)
I don’t believe that Roland had a systematic serial number / date system, so it is sometimes tough to date the amps. it’s in the date range of whenever they were made (Not much help). Basically after the initial JC120 and in parallel with the JC120H, before being replaced with the JC90. (I don’t remember the years off the top of my head).
There’s a pretty comprehensive “fan history” of Roland amps which might have some more details (note: 200+ pages! but: in German), which has the JC77 being manufactured from 1984 to 1996.

There's a Roland serial number decoder online here: http://serial-number-decoder.co.uk/roland/roland.htm

According to that your amp was either made in November 1976 or March 1985.

Guessing the latter based on cestlamort's info above?
