[sdiy] Where there two versions for JX8P ?...

[Bob Weigel]

yeah there are some adjustments on there too.  It could have been that 
they changed op amps in production.  It has happened.  Roland even 
changed various critical parts in some machines like the MKS-80 of 
course.  But not aware of anything notable on the JX-8P.  I'd lean 
towards the adjustments on the filter maybe or...the kind of 
amp/speakers/room/headphones you are playing it through perhaps even 
more likely.  -Bob
