I am thinking of putting two TC Flashback delays for my new studio board. Typical use: First one set for delay, feeding the next one set for sound-on-sound looping (Frippertronics-like stuff). Or, should I feed the TC Flashback (in loop mode) with an El Capistan (or other)? Note: I have a TC Flashback and it is a great little toy. Any thoughts? Any one else running two TC Flashbacks? Thanks in advance!
