It is question publicitairement speaking, a clone pedal Boss DM2 or Ibanez / Maxon AD9. That is the first Japanese analog delays.
Although here is Chinese manufacturing, which motivates many extra musical comments, the price is relatively high.
I do not know if the concept nano pedal has a future but saving space on a PB is eloquent. The frame seems sturdy. No slot for a 9v battery, which makes sense given the size of the craft. The DC plug in is at the top of the pedal and requested to consumption is very low, it is the basic of home basic.
The two mini knobs (echo and intense) are small and frankly not very thin. The setting is no real finesse, musicians eager to wedge their mili second delay to pass their way.
This is the principle of analog delay we are in musical emotion and not in the calculation.
Once adjusted to your liking you can concentrate on the sound, I must say that the pedal is a joke and I found that DM2 a friend had lent me there so many years, with defects and qualities found in many analog delays, but this blur specific pedals sound (pink). That said pedal high volume reveals more segmented contours and an intelligent mix of the dynamics of your playing crucial reveals himself.
He must know what one wants. For more finesse to the MXR Carbon Copy does wonders but lost my taste the famous blur. A fuzzy certe a little cheap but good. What can be done against a bit of nostalgia. A pedal like Proust's madeleine.
Analog delay chip based bucket brigade, the new Chinese models, not the old chips mn3005 that equipped deluxe memory man, dm2, maxon ad ad 80 or 900 ...
Nice pedal in a small package.
Works in 9 or 12v.
Simple with three buttons.
Frankly it is bad. At this level it is better to numerical simulation (eg like the reecho the same brand). For if we compare, as I did with one of his ancestors (AD900), we can find no heat, and self-oscillation is quite ugly. Damage.
Point: it sounds much better in 12v.
A pedal that does its job, but does not present a great interest. I guess the new chips are BBD for something, but the fact that these chips should be calibrated to give the best of themselves. Now in mass production at low cost, it does not forgive.
If the brand offers good models, so do not judge on that one.
