Re: Setting for slapback on a Boss DD-6 Delay
The DD-6 can do soooo much more than just a slapback obviously, but your best bet with it would be to set it for the shortest time, I think it's 80ms? Then just keep the feedback knob set low, and adjust the delay time until you hear a nice slapback sound you like.
If you want a dedicated slapback delay pedal, you could check out Rocktron's Short Timer delay.
