Makes it worse, i think Tim said that you can only wind it so many times before it just starts sucking. He didn't say those exact words but that's the tone of it.
A slight over wind like the over wound Miracle Man to 23k that someone has on this forum is fine but to be honest you don't need to over wind a pickup anyways.
That would be me.
I asked tim to up the power to warpig levels or higher if possible, rather than ask for a specific DC. What came back was 23k, so I guess thats the highest Tim would judge to still sound good. What you or I may think is another matter, but I trust Tims judgment on such things. Its quite mosterous, and sounds fantastic.
If you want to know what a heavily overwound pickup sounds like, try and get your hands on a MkI kent armstrong motherbucker. A mate of mine has one and it clocks in at about 45k (according to the box it came in), four conductor. Its very powerfull, but its also muddy and extremely compressed. 45/23 ~ 2 and its DEFINATELY not twice as high gain as my WPs or overwound miracle man (though there are other factors involved, it may not have that many more turns on it, but have thinner wire). I've tried the MM through his amp, and the MB has more low end, but if anything sounds less hot. And nowhere near as good. The current MkIIs are about 28k, and I cant comment because I havent tried one.
