For a science project, I'm making my own guitar pickups with a combination of these instructions:

and these instructions :

I have 2 questions:

1. I am planning to use neodymium magnets. Do they work well in guitars, or should I use alnicos instead? Here are the magnets I had planned:

2. The science part will be testing different numbers of wraps in the coil. I was planning to make one pickup with 7,000 wraps, one with 8,000 wraps, and one with 9,000 wraps. Is this enough difference to matter, or should I do something like 6,000, 8,000, and 10,000? For what it's worth, I'll be using this wire in the 42 AWG size:

It'll probably depend more on the overall resistence like 8k ohm, 12k ohm, 16k ohm etc. I suspect you'll just have to wind and measure it as you go to get various amounts.

I've never heard of neodymium being used in pickups before, but that doesn't mean you shouldn't use it.

I don't really know that much about magnets, but I think I remember seeing some "overwrapped" pickup having 10800 wraps. It also probably had some kind of thicker wire too, but I don't know about pickup wire guages. Your link to the wire seems legit though.

It would be cool to hear how those sounded!

1. Neodymium magnets are probably a bad idea. More powerful magnets exert more pull on the strings, reducing resonance, sustain and harmonic content. Alnico or ceramic would be better.

2. I'd probably try something like 6,000, 9,000, and 12,000. There'll be a difference between 7k, 8k and 9k, but it'll be subtle enough that non-musicians will definitely not notice.

A 3k wrap difference seems good, but 12,000 wraps sounds like a lot (might take a while to wind, and I'm not sure if they'd all fit). Would it be possible to use 5k, 8k, and 11k, or maybe even 4k, 7k, and 9k; or would that be too few wraps to actually work?

That would absolutely work.

And about the Q-Tuners, I'm not saying neodymium won't work, I'm just saying it has no real benefit, so why spend the extra money?

I couldn't find any alnico magnets that were the correct size (maybe I just don't know where to look). Where could I find some that are 3/16'' tall and 1/4'' across?
