I had one in the past and used it with K&K equipped guitar.
It is definitely good value for the money but I was not satisfied with overall sound quality so I sold it.
For my ears, it added noise and reduced clarity with eq set flat compared to active di-box.
I found blend function rather unusable with K&K type soundboard transducers - maybe it works better with piezo undersaddles.
Interesting fact - when it is in "bypass mode" (led is not lit), it still functions as a DI-BOX/impedance buffer (XLR output). Most of the time I used it that way and set eq on Soundcraft power mixer with better results.
