Hello guys, i think many bassist have this same problem: placing the thumb in the neck pickup gives too much low end sound, and placing it in the bridge p-up give too much trebble... so, I like the most the sound right in the middle...
Then, my solution was this. I wouls like to see other people's works on this. I have a fretless 6er comming, so I'd love to see other ideas.
Started building a little piece of wood painting with a brown cheap marker, then painting it with varnish, then bending 2 planks of metal I found in home, then a rubber piece arrived from somewhere:
Z-shaped metal pieces go inside the wood piece, and below the mics. There is a little rubber rectagle between the mic and the meta, so pressure don't mark the bottom of the mic (not a problem but, it costs zero to make it). There is also another rubber piece between the wood piece and the wood body, yes is the one in the first pict.
Now I can place my thumb there when using B and E strings...
I know is not a big piece of work, but it solved my problem
