In one of the videos des dunnes,(think that is his name) recommeds not having the Fast on with Deep on. Says something to the effect that it confuses the filters having both on at the same time. Question is, in the manual under Relic Mode both are on. Any thoughts as to why he says that in the video when in fact they are both on on the preset Relic mode.. thanks in advance..Sonny.. waiting on the NEW E-trac coming out SOOOON... ha-hope
