There's no such thing as 'theory for bass' or 'theory for piano'. That's a marketing scheme!
There's just music theory. And then you learn, or hopefully already know, the 'layout' of your instrument so you can apply that theory.
Run as fast as you can and as far away as you can from any book that says 'theory for bass'. It's just somebody trying to get your money.
The Jazz Theory book is the most comprehensive book I've every seen for some of the 'conventions' in Jazz music.
And yes, it is in treble clef. But the 'clef' doesn't make it 'instrument specific'. Most good readers will be able to at least 'get by' on treble. But the book isn't meant as a 'reading' book. It's about the concepts.
It's a great resources.
By the way, technique is instrument specific. Theory is not. A major 3rd isn't a 'shape' that's just how it looks in bass. The 'bass theory' books will define it as a shape. But the shape is just a by product of symmetrical tuning. A major 3rd is two whole steps,...on any instrument! Not some of the time, not most of the time, ALL OF THE TIME!
