«  Well »

I do not know how many years I use it with pleasure. It was from his marketing because I expected. The pickup part (magnetic) is a humbucker that captures the vibration of the strings to "how electric guitar" and part mic picks up the body resonance. I use it on democratic guitars I play and test the guitars I build. Customers like that kind of test and several went to buy one after using mine. A beautiful sound reproduction.
