found this nice Sugaree from 1988 with jerry using one of the remoted pedals of his ADA 2FX delay.
at 2:53 he swicthes on the OBEL, and kicks the Distortion off and turns the Delay on. then at 3.03 you see him push the delay time down and ironically can hear the pedal click/pop when he hits the extreme up position of the pedal.
then at about 6.08 you see him flip the OBEL back on with the delay already on. he then goes(at 6:13) and puts the delay fully on and can hear it briefly before he rolls the it back down again. no click/pop the second time.
