The more I think about it the more I feel that you must be absolutely clear in your own mind what situation you were trying to simulate in Photoshop. For example, what is the material in front of the tape deck? If it's white seamless paper, there will be absolutely no reflections, and all shadows. On the other if it's something like clear plexiglass, commonly used in photographing product, it will be almost all reflection and no shadows.
You also need to be absolutely clear in your own mind where the light sources are. For example, if there is a relatively significant light source behind the tape deck, you will clearly get a shadow on most materials. On the other hand, if it is supposed to be mostly lit from the front, you will see almost all reflections, and few shadows, however, in that case, the distribution of light between the front and sides of the object is not currently appropriate. If it was supposed to have been photographed in a light tent, you will likely get a mixture of both shadows and reflections.
It may seem pedantic to force yourself to think in such detailed, concrete terms, but I'm can assure you it will help in the long run when you are trying to simulate a situation like this.
HTH,
