Am I preaching to the already converted here
or did you like me
not know the following:
The "tone" controls of the T-40 - each of them - are split. 10-5 does not affect treble (0-5 does),
but actually activates the extra coil that makes the two pups (at ten in solely singlecoil mode) to full-fledged humbuckers. If you have the two tone controls at 5, only then the bass works with both pups in humbucking mode.
I had never realized that.
I had noticed that the tone controls work "weirdly"
(kind of WALish, you never know what is happening, but it always sounds good!), but never figured it out.
Now the German bass mag Bass Professor had a reverential feature on the T-40
and "explained"
the electronics.
You live and learn. And now I know why "reducing treble" on my T-40 made the bass louder and angrier.
I also finally realize where that glistening presence comes from which is quite unlike any other bass: The T-40 is a singlecoil bass unless you adjust the "tone" knobs.
Or was I just stupid?
Please be gentle with me.
