Last update; transducer arived yesterday and after experimenting with the place I found that the best spot was directly behind the bridge in the middle.

Sound of the transducer is very poor and bad and to weak to even turn the tuner in the preamp on so basically worthless but hey, it did only cost 1$ so no big loss.

So final decision is no more build in PU for know and enjoy the sound of the bone nut and saddle.

In the past already tried the PU's that you build in the soundhole but they are to sensitive and create a lot of feedback issues.
