If this is too redundant, I apologize and will delete. However, I am looking into both of these now. About a week or two ago, I was certain i was going to get a Space Echo. Now after looking at features on both models, I am leaning towards a DD20. I want this to be a discussion as to for my needs, and based on your trials/ownership, what would be the better suit for me. I love the type of delay sounds EJ gets on his solos. It is ambient and doesnt take over. You hear the trails but it feels apart of the guitar (I know a lot of that is attributed to his overall rig too and echoplexes). I currently use a (dont laugh) Behringer Delay as my main solo sound. I am happy with the sound but want to upgrade. I also use a H20 in tandem at times for ambient sounds and even longer ambient trails. I like the slap back sound but it is not my go to sound. Ambience is basically my thing as I like to fill space in the songs/rooms with my band where it is needed; tastefully. I am in a rock band playing originals..rock as in mxing STP w/ Live w/ Blues and 90's influences. Based on what I have researched, these are the feautures I like/dislike; this is what i ahve found in both Space Echo: -Clips (and name even) do the ambient thing well -Tap tempo -EQ on the repeats (bass, treb) -Click wheel = easy access to 12 different sounds/modes -Buttons appear to be very easy to work -No presets? -No modulation? DD20: -Clips sound good and it can do ambience/tape/analog/modulate/reverse -tap tempo -memory for presets -Looper -more buttons = seems harder to work -ambient sounds as good as RE-20? Im not good with difficult pedals. But I am willing to put in the learning curve for these two, but the RE-20 just seems like it would be a breeze to work with by the looks of it. Lastly, are each fo these better out front or in the loop? I am using a Fender Hot Rod Deluxe now and wont be changing that for quite some time. Thanks for any input.
