I never used a lot of delay (blues rock guy!) but I enjoy playing around with it. I bought this an the Echorec, intending to keep only one, and probably the Echorec which is more in keeping with my 70s penchant.
I love the Dig!! While the 80s might conjure up cheezy memories, this pedal can give you really vibey tones. With two delays and mod you have access to a lot of fun tricks:
1. Standard delay repeats, over a pad of reverb by setting delay 2 to a fast time and high repeats, but low volume.
2. A rhythmic or polyrhtymic backing track - if you use the repeats function which loops the delay without adding to it
3. Lots of different rhythm combos that inspire your playing as the different delays interact and as you play with serial and parallel settings
4. A really good chorus / flange / phase if you turn the delay time short and the mod on
I never thought I'd have a delay pedal nearly always on. Oh, and fed into a very subtly-set Echorec, it sounds amazing. Yeah, you really need three delays :)
