More sustain and a bit more balls I would say.
More balls, sounds interesting ^^
I have had a hardtail Strat for 30 odd years. Mine is a mid 1970's -so called bad period for Fender. Mine is a superb instrument and sounds terrific. It has Apaches in it and sounds like a great early Stat. I would say that in comparison to my trem equipped Jap Strat, it has a slightly warmer tone but there are too many variables to make a straight comparison ( my Jap Strat has Slowhands). I think that to an extent, the Slowhands compensate for the slight lack of warmth( I am remembering back to when it had stock pups) so it is hard to provide a clear opinion. I think it is more to do with the playability with a bit more "give" with the trem Strat.
I also have 76's tele, it sounds nice. A bit heavy but really sing through the band.
How Apaches sounds? I have a Ash body Maple neck Strat waiting in line to be made.
I also have Semour duncan Antiquity Texas Hot for the strat.
But after I hear 59' slap board in my friend Strat, I start a search on Apaches info.
The Antiquity really sound nice in vintage vintage tone, a lot of vintage ambiance and texture.
Bareknuckle 59's sounds to me in the difference way, more clarity, contrast, dynamic and details.
Of cause, it sounds vintage but do not have the vintage ambiance and texture that Antiquity provide.
