After my bride ran off during the wedding, we finally got back together and the honeymoon is over. Malekko did a great job in the customer service department and I commend him for it.
To all who did not know, most[all?] of the first batch 616's had calibration issues which made it the delayed notes distort too much. Malekko recalled them and i got a free T-shirt out of it
So here's the D.L.
It's a bucket-brigade analog delay. Similar to that of...let's say a EHX Memory Man. (Not sure if the Memory Boy uses a BBD chip...)
The controls are simple like the MXR Carbon Copy. Modulation on/off, speed, depth and Truebypass/Buffer Bypass occupy the top row of controls. The True bypass/Buffer controls really stand out on the tone of the delay. The Buffer sounds much more bright where as the TBP sounds a lot darker.
IMO, the modulation sounds best with that little hint of it which means the Depth pushed up a bit and the speed on zero. I'm not a fan of trippy modulation. You be the judge in this regard.
The bottom row of controls are Time(~600ms), Mix, and Regen(Feedback). Like all the reviews have mentioned, the oscillation on this is incredible. Almost as good as the Echobox's
All in all, it's not a Carbon copy killer for me. Actually, it can sit right next to the thing. I believe they both have very different sounds. I do like the control of the modulation and more versatility of the 616 though. But we'll see if MXR makes a CC v2....
