I use the KK Baby Bass for mostly blues, americana, and roots material. I get many compliments on the tone and look of the instrument. Anyway - the other week, I did try out a
Bass Max Piezo pickup on the bass. There was a stronger output, but not an improvement in the tone, to my ears. It wasn't bad - but not as even sounding as the original
pickups in the KK. I ended up pulling it out and keeping things simple for now. I may give it another try - but in the end...I kind of felt like I wasted $100.
