Except that you don't like splitting low gain pickups and that I recommend this solution. :laugh2:
It surely illustrates the variety and relativity of personal experiences, tastes and opinions.
Now, I also think that it shows the limitations of generalizations: the current market being crowded by so many low gain / hi-gain humbuckers (sometimes with very different designs) , there's a probability of good/bad sounding split options in each range... ;-)
Footnote to my previous answer - Actually, I DO HAVE a guitar with 2 hi-gain HB's and split option: that's all I could obtain from a single push-pull pot mastering two humbuckers. On this basis, I confirm that splitting a hi-gain HB doesn"t sound single coilish enough but easily delivers too much noise (albeit my pickups in this instrument are Bill Lawrence L500's, rather less noisy than other products in HB mode).
