Bobbin Position - affect on output?

[TheGrateOz]

Hi, I have made a number of humbuckers, but have been experimenting with a new design. All sounds good on it, but it's a bit weak on output.

Could bobbins not being the same height have an affect on output? What if they aren't aligned top to bottom? - one higher than the other?

Any other comments or help is appreciated!

A taller bobbin a should have a brighter tone than a standard height bobbin ,but with the same number of turns as a shorter bobbin ,It will use less wire & can sound thin

Thank you. What if I have two different height bobbins on a humbucker?

I've made them that way, but I Shim the shorter one on the bottom so they are level on top.
My Hybrid Bucker that has one blade and one screw bobbin is that way.

Here's a picture of that one.
The Screw bobbin is shorter.

Looks pretty much the same as mine. Mine measures 14.3K across the 2 bobbins. Just cant figure out why this thing is weak...sounds good, just weak.

Mine is 2 different gauges, and is about 13.5k.
It is sure not weak by any means.
Did you use a shim between the magnet and the blade bobbin.
a regular magnet is not wide enough and you have to make a steel shim.
If you don't it would probably be weak.

I you think it's weak .do you have the magnet charged ?

Glad I could help.
It doesn't take much Thickness.
Another option is a small piece of soft steel wire, like the old baling wire.
Something that fits snug in between the length of the magnet, and one bobbin.
On my hybrid I put the magnet against the bobbin with the most wire, and shim the lesser bobbin.
Good Luck,
Terry

We need Sound clips.
What Magnets do you like In it.
I liked A8, C5, and A2.
Not a big A5 Fan.

That sounds more like TOO MUCH coffee, actually.
