Grado Black P-Mount sound box.
An excellent sound box for the price. The Gradon entry-level sound box will not leave you cold!
Gradon Black, Green, Blue and Red boxes have the same frame.
By changing the needle to a higher quality one, you can easily improve the sound quality of your record player.
So you can replace, for example, a Blue needle in the Black box, and the sound quality will improve.
