I also love P-90s. This is my H170 from 2014. Spruce back, very flamey maple top, ebony fretboard with 5mm pearl dots, 5-piece neck and ThroBak P-90s.
It was Fab getting guitars built by Heritage. Good Times.
I agree that the half & half fretboard inlays were not the best design.
I had Heritage correct that with a Millie custom build in 2011.
Sunburst Spruce Millie from 2011 on the right Millie SuperLight from 2017 on the left.
I had a change in guitar philosophy in my later custom builds preferring more wood less shell.
I saw Johnny Winter in a medium size club and he was playing through 2 Fender Twins with JBLs stacked on top of each other. That's 170 watts of power through 4 JBL 12s. It was loud. Good times.
