I use it for 2 months now.
I had a Fishman and a Shadow BP100B SH965NFXB before this one.

The sound of the Realist rendering is much more acoustic than the two mentioned above. I'm very happy. Note that I played almost exclusively fingers.

I place it at the base of the foot, this is where I get the best sound.
There are a lot of mids in the sound, it is therefore imperative to go through an equalizer to correct it.
For my part I cut all that is around 1.5 kHz and I note a little around 150Hz and I get a sound very close to my acoustic sound.

Being able to remove and replace so easily is a real plus: I can take it and place it on a bass loan for example.

For the negative sides, first I would say the price, a price I think.
Then it is a sensor so the sound is fairly straight and lacks a little depth. I can solve this problem by adding some reverb or better yet, associating it with a microphone.

As perfection does not exist, I do not 10/10 but it's really a very good sensor that deserves its 8/10.
