you'll be happy with a dd-6, its a good delay, though I dont know if it takes external tap tempo; i think that was the dd-5; I imagine it does have the 'hold down 2 secs' tap input though. tap tempo is the greatest pedal idea ever, i have my dd-20 set up for tap tempo in the dm-2 mode mostly and i have a empress tap tremolo too; i don't kow how i coped without them! congrats on the dd-6 be sure to let us know how it works out!
