One of the great subtractive analogs of all time. If anyone has circuit summary please submit it.
Never seen one here. Any help appreciated on tech tips.
Roland still stocks many parts for older instruments! You can always order them through your local Service Center and see what happens! Otherwise I have some parts also so don't hesitate to ask.
