The main reason why i purchased this delay were the two storable channels.
The Harley Benton D-Seed has got four different modes:
Digital - This one sounds great. I couldn't hear any sound losses and it gets up to 6 seconds delay!
Analog - I don't use this one very much, because i already have a great sounding analog delay. But it also sounds great, compared to the (more expensive) one i've got.
Modulation - Hard to describe. Sounds very good and mixes in some kind of chrous to the delay. If you like more experimental sounds, this would be the one of your choice.
Reverse - The only channel i wouldn't recommend. Compared to other reverse delays it seems like the reversed delay-sound gets "cut off".
The controls are self-explaining:
Mix - Turn it to the left, to hear more clean-guitar-sound. Turn it right and you will hear more delay and less clean signal
Mode - With this one you switch between the four modes explained above.
Time - This knob controls the delay time. In digital mode it goes up to 6 seconds!
F.Back - It controls the feedback of the delayed signal.
All knobs are confortable to turn. Not to heavy and to too slight. The mode knob snaps in on the channel you choose.
You can even save two of your favourite sets. Great feature, which is hard to find in this price range. With the left footswitch you switch between channel A and B. With the right footswitch you turn the bypass on and off.
Finally it has got a tap tempo. This is why i only gave 4 stars to the handling. To tap, you have to press the two footswitches at the same time to tap in. I sometimes had some trouble with it, that i accidentally turned the pedal into bypass or changed the channel.
All in all i would strongly recommend it.
