Having Your Delay And Eating It When it comes to delays it's safe to say Boss have you covered. The DM-2 and now the Waza version has analog delay down, the DD-3(T) gives us the crisp digital delays and we even have the original space echo doing the tape thing which is replicated extremely well by the RE-20. Then we have the mothership, the DD-500 which does everything anyone could dream of and a whole bunch more. The trade off we make is as the pedals become more complex they generally become larger but now Boss have created a compact pedal with enough options to cover even the biggest delay fan ... yes ... you! We all know complex boss delays aren't new, the DD-7 is famous for sounding amazing and doing almost everything. So what can the DD-8 bring to the party to make it a worthy update.
First thing has to be the additional delay types, the dd-7 already had 4 digital settings, a hold function plus modulate, analog and reverse. The DD-8 adds Standard (Digital), Tape, Warm, Shimmer, Warp and GLT, PLUS an add Reverb option AND A LOOPER!!!!! That is a pretty big upgrade, you can A/B this on tonepedia with the DD-7 to hear all the tones are still here plus a whole lot more including a multitude of fun tricks onboard.
This is the sort of pedal which people buy for their smaller board then use on their big boards, simple enough to use yet enough options like the reverb, looper and tap tempo to not just add to your tones but potentially replace a few other pedals while you're at it!
Boss have been pretty clear about this, The Most Powerful Compact Ever ... and it's easy to understand why.
