Query: Dubious Effect's Worst Incarnation

I went through two of these before giving up. Both had noisy pots and I found the effect more trouble than it was worth.This is a very old and broadly-misunderstood effect that still stirs much controversy. I think it still may be of limited utility in certain studio mastering functions -- where it is best applied as a VST -- but it has little place with personal stage gear. It is generally reviled among more experienced musicians and especially by FOH sound techs, who find the effect disruptive to the house mix when used on individual instruments.In converting the chip to work on 9VDC, numerous compromises were made compared to the 120VAC rack units. According to BBE, the unit has less headroom than even the cheapest rack version, now discontinued.Pass on this.
