A few years back I bought a couple of brand new Washburn solid body electrics
factory fitted with "Buzz Feiten Tuning System"

After I bodged about adjusting the bridge height and truss rod, they were sort of intonated ok enough by ear,
though the theory of it was a bit too much of a faff to be bothered with.

I eventually aquired an expensive Planet Waves strobe tuner with adjusted "Buzz Feiten Tuning System" presets.
