I have NFI, but #2 sounds "fuller" almost as if it is capturing the resonating body of the instrument, not just the (isolated?) vibration of the string (as in #1.)
Also - are we hearing ONLY the transducer, and ZERO of the un-transduced, acoustic sound of the bass?
I need more hard data to make my uninformed decision.
Please and Thank You!
Yes.'three dimensional'.
No idea either but definitely prefer ch.2
Channel 1 KNA piezo.
Channel 2 Ischell contact mic.
Thanks for the demo, Rick! Very useful. The difference was clear. You could hear the piezo honk on ch.1. But this was in your living room all alone with your bass and with lowish output volume.
What about on a stage with drums and guitar smokin´next to you? Can you still here the difference and does the mic bleed? Maybe one can eq the honk out a bit... You may also start to think about the price difference between these two transducers. And maybe the piezo starts to feel quite reasonable
And yes, I know you like your KNA. I also like mine and my Full Circle. It´s always nice to blend in some mic though![]()
Just goes to show me that as someone actually trying to make a living doing this, I could use the kna and sound almost as good and save $900, or over a week of $100 gigs. A lot of these boutique gear items are for established stars or hobbyists with real jobs.
... why I need 3 or 4 pre-amps ...

Why??? For the 3 or 4 new double basses that you need to get, of course.![]()
