your sig says you only play Japanese basses... lol. im agreeing its a HWY1 bass
As the pictures I posted show, it isn't a HWY 1 Bass.
Even if the logo was replaced, the HWY 1's fingerboard has a flat bottom. The bass he's looking at has a curved bottom on the rosewood.
Pictures make it tough to determine authenticity, but it looks MOST like a 70-75 P Bass judging by the logo, the curved radius on the bottom of the fingerboard, the tuners, the way the burst is sprayed, etc..
