Hey Guys, I'm in the market for something to loop riffs for playing multiple guitar parts ontop of one another. I'm hearing from some to go with the DD-20 and some to go with the DL4. I've fooled around with the DL-4, it's a cool pedal, but have yet to mess around with the DD-20. Will the DD-20 allow me to loop riffs over one another? essentially that's what i'm looking for, but I really don't know much about it. I know that the DL-4 can do this, but I hear from alot of people that they're junk, and a part of me wants to write off line 6 alltogether for the sole purpose that their amps are trash. Let me know what you guys think! Thanks.
