ST-20HSS SBK Standard Series : Generally satisfied, but...

This is my first electric guitar. I have only played acoustic before. In general, very satisfied. Sounds great. The scale was immediately set up as it should. Only one serious problem for me, the springs that are located on the back of the guitar under the cover are rusty. A very unfortunate fact. I understand some possible roughness, unevenness (of which there are not so many), yet this is partly due to the low price. But here are rusty springs, this is a very unpleasant case. I understand that they will have to be changed immediately, since how long the tremolo will work like this is not known. I hope this is only a jamb of my copy, since in general I am satisfied with the guitar. To start playing the electric guitar - that's it.
