So, I took the plunge about a month ago and got a stereo Yama with a Felix. I was using a B Band first gen with blend box before, and this thing picks up where that leaves off. First thing I noticed was how little top end noise there was. Second, I arco a bunch and I now do not have to accommodate for the unbalanced amount of signal between pizz and arco. The Yamahiko picks up less which allows the bass to provide more acoustic signal to the room to help balance the overall volume. The low pass on the Felix might be the best and most underrated knob on the whole device. I will be upgrading to a powered cab in the future but in the mean time, my WW is pretty flat and the EA cab has the mid and tweet wide open. Everything you all have said about this pickup is 100% true and I love how the pickup takes nothing away from the vibration of the instrument.
If Rick Wolf’s demos of the KNB-1 Cremona, are any indication , it’s a far superior pickup to the older pizeos demonstrated in the video. That said I like the demo.
