I have some specific questions about the difference in quality between the different neck makers. I know that at least pricewise, there's a top tier, occupied by Warmoth and USA Guitar Works, a second tier, occupied by Allparts, WD, Mighty Mite, and a third tier with all the rest (Saga, Axl, any others in that range). Please excuse any omissions I may have made. My questions are as follows. 1) For those of you who have owned necks from, say, Warmoth and Mighty Mite: What can I expect from Warmoth in terms of tone, durability and playability that I cannot get from Mighty Mite or Allparts? It's very important for me to say that I'm not looking for vague "it just feels/sounds/plays better" answers, but specific things that the top-tier products do better than the second tier. I'm trying to sort the facts from the hype. 2) It seems that there are no reasonably-priced necks with the truss rod adjustment at the heel. I've noticed that almost every high-end Fender-style builder uses a neck that adjusts at the heel, like most of the non '70s Fenders do. Is this due to simple tradition or are necks with the truss rod adjustment at the heel inherently superior to those that adjust from the headstock? 3) I'm aware that USA Fender is all over the place in terms of quality, but where, on average, would you place their necks in comparison with the makers I mentioned? Be sure to mentally remove the headstock decal before you answer this question. I'm not asking how popular Fender products are, but how good they are.
