Everything is said here: http://www.visualsound.net/index.php/products/garagetone_pedals/axle_grease_delay

2 things that bother me already: have to unscrew the bottom of the pedal to put a battery and the switch that makes a big plop when pressed ... Why are they not all switches that make no noise? It exists!
Otherwise, it's a good little pedal, simple, metal box, jacks that seem resistant.
The knobs are a little cheap, but their race is progressive, not too easy or too hard to turn.

UTILIZATION

Simple Config: 3 knobs
One-time
-One for the number of repetitions
One-volume rehearsals.

The manual is concise but adequate and provides examples of settings.

SOUND QUALITY

Used with Fender Tele, distal palmer on Kustom amp.
It is a very good analog delay, I was pleasantly surprised, really easy to adjust, does not distort the sound when turned off (high-pass), no variation in volume between on / off.
Rehearsals on the other hand are not completely faithful to the original sound (at the same time it is not digital), a knob tone was welcome nonetheless.
Opportunity to do go on testicle with extreme settings, I enjoyed myself.
The delay time is approximately 450ms announced, on the one I tested was higher (towards 550/600ms)
Most

OVERALL OPINION

:
Strength-
-Simplicity
-Sounds
-Price (69 euros where I've tried)
-Size (easy to squeeze in a pedalboard)

Les:
-Access to battery
Absence of tone
-No LED that flashes as a function of time delay, it would have been handy.
