The design of each element should be thought out in order to be easy to make and easy to repair.

If something is easy to repair, it is easy to construct.

I was always able to see the defects in the design of an instrument which overlooked completely the need of its maintenance.

Let there be bass.

I wonder if I could make an electric bass.

Ah, I could make it in the shape of a guitar, and it would a) be more affordable, and b) a guitar player could double on this instrument.
