Good work!
I got few crits:
1 - biggest thing for me is plastic. In the real thing, its quite SSS'y...And not as reflective, more of a fresnel.
2 - its hard to tell how you modeled the glass panel with the arrow indicator. In the reference the glass panel is infront of the orange arrow, and is casting a semi shadow onto the back plating. I cant tell in your model if this is the same way...if yes, its not casting any kind of shadow...maybe it should

.
3 - if you look at the handle its slightly bent inwards. And the glass around the front panel has a multi edging giving it an interesting refreaction along the edges.
4 - The riges around the tuner nob are quite a bit more smaller in the photo.
Good work overall !
