Weird guitar...

[beast]

I built a bass guitar, and I connected the strings to the back to the
neck truss to form a loop around the pick ups. The idea is to close
the loop so that when the string vibrates, it will generate current
inside the loop that will be picked up by the pick up, and thus
increase the output of the circuit. I added a strong magnet near the
strings to increase the magnetic field so that more current will be
generated in the loop.

Can anyone tell me what they think of this idea?

I think it will not work. Your guitars pick up picks up the variation
of the magnetic field because the string moves in the pick ups field.
The strong magnet is already present in the pick up. Adding more
magnets gives forces in that point in the string, what may make it
behave less linear, and sound less.

But what's more important: there is no point is trying to get a higher
output. What usually is needed (yes, I modified my guitar myself) is:
- a good signal to noise ratio
- the desired frequency spectrum giving the desired sound

You can reach this by proper shielding, making sure grounding is the
way it should be, and correct components are chosen. Often the tone
control capacitors are too large.

I tried it last weekend, and it turned out very nice. The sound is
just incredible, very rich and very full. When I added a back truss
to the neck it changed the capacitance of the circuit and affected
the tone, that's what prompted me to complete the string coil by
connecting the back piece which is made of steel strip 2x16" bent at
the end to hold the strings, connected to the neck truss via a screw
through the strip, next I connected the neck truss to the strings
with a copper wire, to complete the loop. I added the magnet at the
base of the neck, above the pick-up.

Then I took it to the club and played with it, to hear the
difference.
It sounds very good....
