I'm looking for a nice pristine sounding delay (clear repeats) with a good accurate tap tempo that can subdivide at dotted 8ths and quarter note triplets. And a separate tap button, I hate that dual-function button thing. Is the DD-7 a good candidate for this? I know it wants an external tap switch, but given that I get either the Boss or another tap footswitch, is this what I'm looking for? Or is there a better/cheaper one?
