This is a delay that definetely has a lot of character. If you're looking for classic delay sounds, there are better options. But for me, it gives me exactly what i expected from it after watching some videos : those dark murky delay sounds that evoque spaghetti westerns, David Lynch movies, or Neil Young (Dead man era). It works also well for modern country sounds (i.e. Neko case)
The only minor concern I might have is that turning up the viscosity control adds some annoying noise, but I don't think the real interest of the Adineko is its modulation. I rated the sound 4 stars for objectivity, but for my own use, I would rate it 5 stars.
The other controls are all useful and efficient. I especially like the reverb control, which sets the number of repeats. Some magic happens when it is set at the edge of self-oscillation. It reminds me a lot of an old Echolette tube tape echo I used to have.
The blend control is also pretty useful to create rythmic patterns.
Though it can be run at 18V for more headroom, I find it has much more character at 9V.
I run it nearly last in my pedal chain, the very last beeing a Dawner prince Boonar (echorec). Some crazy rythmic delays can be achieved by stacking the 2. I run all my pedals in front of the amp. The Adineko works well clean and after gain pedals (overdrives and fuzz).
No issue with quality so far. This is my 7th Catalinbread pedal in the last 10 years or so, never had any complaint with the brand.
