I have been looking around for over a year and finally decided to buy one of these. It arrived yesterday, on time. The form factor was not quite the same as my fretboard (being symmetrical and thinner). I had no problem with the special tape. My previous setup was P-bass innards attached with Lego and double sided tape (which came unstuck at least once a year). I left the tape to rest overnight for the glue to set nicely. Had a bit of a play this morning. The first place I attached the Krivo seemed balanced between the 4 strings and I could easily tune. Played a couple of songs and minigames on Rocksmith and it worked flawlessly, never complaining to be too loud or soft and identifying notes with ease. (also tried my bow which seemed ok but I have never learnt properly) Tried to get some feedback through my amp and could not. All in all work exactly as I hoped, looks neater than Lego and should last much longer. I didn't find have a photo of my Lego pickup on my bass. The control were hidden & held behind the fretboard with picture frame tape, and the pickups hung down on an angle with tape & string and the lego man spaced them appart with some bluetack. It worked fine but fell off occasionally and my wife did not approve.
