I'm looking around the market for a Delay pedal, and reckon I'm gunna get the Boss dd-3 or dd-7, both seem good value for money - but was wondering if anyone could help me out with one question (which will probably be the deciding factor)

I have tried the dd-7 and it has a feature where I can play a rhythm, and then have it loop indefinately (and thus I can lay some lead over the top for as long as I want it). What I want to know is, does the dd-3 have the same feature?
