I've got Mother's Milks and Irish Tours. The neck-MM really has this Frusciante-tone and -vibe. It's woody, bright and sparkling. It handles gain well. For some meat you could also think about an IT-neck. It has more bass and mids and if you roll the vol.knob a tad back you get in MM-terrority. Not quite as woody as the MM though. With quite some gain I like the IT a bit better, but both are awesome singlecoils.
