I went and saw Phil Brown last night and he was using a DL4 with his rig and was using alot of the volume swell feature. It sounded great. I was wondering, does the DD20 offer this feature and/or, what other pedal will do this. I have several good delays/ echos, and not sure if I would want to unload one or two to get this effect. I have a TTE, deluxe memoryman, dd5, dm2. They all sound good. But, if I could find one that would give me what the Memory Man gives me and what the dd5 gives me, plus the swell feature, well I'm thinking that that may be the one to have. So far, I can tell that the DL4 could fit the bill but there seems to be reliability issues in the reviews. The DD20 seems to do everything pretty well and seems to be relieable but doesn't make mention anywhere of having this swell feature. Your input would be appreciated. Jeff.
