Boss Dd3 Vs Dd7
Dd7 does all of that with much longer repeats possible plus various analogue sim and modulated delays.
Boss dd3 vs dd7. I think dd3 is an earlier simpler digital delay and it just does unaltered clean repeats to a moderate max time is it about 0 6s max per repeat. There is no doubt that dd7 gives a lot of value. It has everything that dd3 has more exciting features like the hold mode which actually gives you a 40 second loop the modulated delay and the external footswitch integration. The dd7 is about 100 used.
The delay time is much longer and i believe the hold function can be used as a 40 second looper. Internal and external tap tempo with 3 subdivisions or expression pedal control if you don t need those features then the dd3 is probably a good choice.
