Hehehe....
Randolf's hi cut mod for the DD3 is a must have, compulsory mod IMO.
With no hi cut, you get the standard fare, nice if you want your delay heard...
With hi cut on, you get to have a revishish, echo-ish effect, very cool for just wetting the tone up.
With a LOT of hi cut on... woah... very very nice. Though, your delay can't really be heard in the mix lah..
