Ease of Use:
Horrible. I have to pull out the manual everytime I want to add delay to a patch. the worrst I have ever used in 25+ years as a working musician. Just horrible. To my way of thinking, this could not be more confusing (and I've had 2 for over 5 years).
I will never buy another product from them.
Sound Quality:
I use the unit between my preamp (RealTube II) and power amp (Carvin Tube 100). Over all I am happy with the sound.
Reliability:
I've used the rig for 5 years. It has never failed on me.
Customer Support:
RTFM. It's all in there. that is the first response I got from them. It took me 6 months to finally contact them again, and this time I got something written in English (my native language).
Overall Rating:
Sounds great. I can just never figure out how to tweek it, so I usually use the presets. I would have been happier with something from Digitech, Roland, or any number of other manufacturers products I have used and don't need to spend an hour with a poorly written, poorly organized, and basically worthless manual. And forget about intuitive use…
