Not that this helps you but my Memory Boy exhibits low-fidelity repeats when the delay knob is turned past 2:00. Sometimes it doesn’t repeat at all. It does make warbly synth-y sounds when the knob is turned that high. I’ll listen for hiss when I get mine back. It’s at EHX because it was making a popping (and repeated popping) sound when I engaged it.

Otherwise it is an amazing pedal.

For what it is worth I also have an MXR Carbon Copy. The delays get longer when delay knob is turned clockwise, not the other way. Same as the MB.

Someone should really write a book on the history of the delay effect since the first echo units (from Echolette to Eventide) :lightbulb:

Hmmm, maybe that someone should be me. That would be a huge seller, at least on effects forums.

It helps to know the colorful history of the delay effect when appreciating the nuances of analog delays. Analog delays (tape, or BBD) have always had flaws, idiosyncracies, particularities, inconveniences, noise, lo fidelity, short delay times, etc. ad nauseum. Then when the microchip allowed for the first digital delays in the early 80s, everyone went apeshit over them. That is, until, the 90s when everyone started to long for the lo fidelity characteristics of analog again. Words like “warm” and “organic” suddenly became all important to guitarists.

So yes, the Memory Boy has analog characteristics, which are flawed by nature; but those very flaws are coveted by many. They aren’t’ everyone’s bag, and thankfully there are multitudes of choices in delays out there to satisfy your delay needs.

Regarding control voltage on the MB’s exp. pedal input, the useable range is 0V to 5V. Putting in 0V to 10V won’t do any damage, try not to exceed this range though.
