I like the 1.5 nut but how are they back to front?
They were pretty slim as I recall. Both are sitting in a local store waiting for their forever homes, so I can't measure...
I remember them being pretty comfy, but my tastes are esoteric -- I'll play my 68 Fender Telecaster bass with a huge wide fat neck, and then my MIJ Jazz with a slim neck, then my Aerodyne with a modern C, then my P with the Lowe conversion neck, then...
And I like them all.
