I made a smaller box and placed it under the saddle line
The tone is very clean there
1) With 4.2 Mo input impedance FET preamp
2) Direct
The only problem is that I had to uninstall it once and I struggled against the tape.... Then I heard a "crack"
Now the guitar lost all its low end... Hope is just the pickup and not a lose brace.
The guitar sounds acoustically like a V-braced Taylor or E10om... super bright.
