I use it on old Austro-Hungarian kontrabass(100+ yrs old), I play a lot with bow and this pickup has better bow sound than realist, underwood(and shadow sh950) and fishman BP-100.
I use only ONE pickup (below E string bridge foot) it has clearer sound than when I use both pickups. This is because arco was sounding like on contra phase and pizz was more fretless bass sound than kontrabass sound... I met a guy with same pickup on some festival and I suggested him to try only with one piezo and the result was great(and he buy me a beer). He was about to sell this pickup and buy a realist, just because of pizz sound, but he also does not like arco on realist.
pizz is with massive bass so sometimes I must put down bass EQ on amp or preamp. Most time I use flat EQ on preamp and amp, depend of space where is gig and what kind of music.
I use Evah Pirazzi strings and pizz growl is perfect.
Before this pickup i used fishman BP-100 for 15yrs but setup was not like they recommend. i put both piezo plates on one leg(e string) down next to belly from both sides of bridge and make a U clip to fit them properly. pizz was great but arco was too sharp, but still better than realist and uderwoodlike pickups...
I tested all of them on my kontrabass with my friend who has realist on one bass and sh950 on other bass...
I use Fishman Pro-EQ Platinum Bass Preamp for mixing desk and GK MB-112 amp on stage.
I play jazz and latino standards, then I play with some popular(in Serbia) folk pop band, I play free improvised music, and I do acoustic covers with some band...
Hope this was helpful, and if I had any spelling and grammar mistakes - sorry about my English
