Not having a memory man pedal (which is the inspiration for this mini pedal) I cannot compare to the original, but I can speak about the sound by itself.
The repeats are very warm, and clearly degrade with each repeat (as expected from an analog echo), preventing them from being in the way of the original sound. Adding a small amount of modulation can add texture to slow passages and feels particularly lush in the vibrato setting.
Comparing to my other analog delay (a Seymour Duncan Vapor Trail), the controls are different, which made it initially less intuitive. The sound is also warmer and degrades more quickly than the Vapor Trail (although both are analog). The Feedback knob, which makes the number of repeats depend on how hard the strings are hit and can sustain self-feedback. It needs some time getting used to, but let's you change the sound by changing the picking.
The knobs are also solidly built and comfortable to use, which is something rare for mini pedals.
