Have only sat with the device for a couple of hours, but the recommended power supply (Thomann NT 0910 AC/PSA) adds so much noise to the signal that I consider the combination pretty much unusable. Maybe I was unlucky and got a B-unit, but I would definitely recommend against buying that power supply to use with the Ditto+. All items (amp+ditto) were connected through a power conditioner strip. When the power supply is not plugged in and the device is in pass-through mode the signal is clean and noise free.
The device comes with basically no manual except for a quick-starter page, and the Extended Play function (or how to use it) is not mentioned anywhere. I had to google to find out. Same for info on how to update the firmware. Also no info on how to find out what the present firmware version is.
Apart from that it seem to be as advertised, but I feel so disheartened by the hissy sound that I won't be using this until I get a more high-quality power supply sorted. I might extend this review once I get a chance to play with the device hum-free, presuming that is still on the table. Might also update my start ratings at that point.
I found it quite hard to sync the loop start and end properly but maybe that will improve with practice.
EDIT: finally got a replacement power supply (Harley Benton PowerPlant ISO-1 Pro) and now the sound is excellent with no distortions or hiss.
Having used the device for a while now I think it's a great little thing, but it does get really confusing with only a single button to control all the functions (play, stop, record, undo/redo). Occasionally you end up accidentally deleting the entire track and then - and this is really stupid - once you delete the main track you can no longer use undo to get it back! Undo only works on the last take. This should really be changed by the manufacturers. Others than that, quite happy with it.
