I understand Sid's point completely. I do have several analog delays and one (no, make that two digitals - The ToysR'us special and an EarthQuacker devices Disaster Transport).
I will be buying an Eventide Timefactor. I will eventually end up with two (2) delays on my board . . .an analog (hopefully, the Echoczar - someday) and the Eventide. Two different useable applications.
Yea I was going to suggest the DL4. Has the tap tempo, nice clean sound with no tone loss. Its true bypass unless you switch it up to allow trail offs when you bypass the pedal. Even then I havn't noticed any tonal degredation whatsoever. PLua ita packed with loads of features. I like them so much I have two of them on my baord to cover my digital delay/looping needs.
If you get one...get the newer model with the block logo on the face..apparently the script ones have reliability issues.
I will praise my love of the Nova, yet again!
Great features, great tone.
