Another thing that puts these 2 pedals apart is the sonic qualities of the wet signal, especially with a considerable amount of repeats.

With the Timeline, the repeats will create a “reverb” type of sound when they sum each other.

With the Timefactor (and Boss DD-500), you will get clear and more defined repeats, but due to the dual-delay feature, you could be able to recreate that “reverb” sound I’m talking about very easily.
