Interesting. Yeah, pickup height is still yet to be adjusted with any real consistency.
I even need more foam in there if I want them higher. They vary from 3-5mm from the strings with the last fret fretted. I need to try some different heights. The bridge one is the furthest unsurprisingly.
Here’s another curious point... the GFS pickups didn’t come with either springs or foam. I guess they are usually used as replacement pickups so some existing hardware is expected. I had to cut up some of the foam left over from installing the Toneriders in the JZ-1.
