Hello. I bought a Carlos J. CS sensor and I simply don't know where to put it. I followed the manual and tried to find sweet spot on the top outside. But I want it inside and when I tried it in the same places there were brances or the sound was different...much worst. Lot of hights no bass or boxy sound. So I tried different places and I'm desperate. In every try I have to loosen the strings and tune it again and find somebody with small hand. Feel pain for strings and neck. And M3 sticker doesn't work after few try. So my question is: Is there any safe place, some tip? Is it that big difference between putting it outside or inside? I have typical selmer oval with brancing similar to the picture. Thanks a lot for all your advice!
