Hello,
as of reccently my SC1000 progressive line has the following issue:
whenever i pluck a string there is no sound at all however if i touch any part of any string with my finger and pluck the string again there is sound.
this goes for all strings. I can be touching the E string and pluck any other and sound comes out normally. as soon as i let go and just pluck the string again no sound
anybody familiar with this?

This is not the true. This is true only about EMGs, which have special design including additional EMI shield. Other pickups, active or passive, need grounding of the strings. This is basically not about active or passive design. Grounded strings acting like Farraday's cage, but if are not grounded, acting like a antenna for EMI.
Nevertheless, SC-1000 has serious grounding problem from the factory. Bridge and tailpiece are painted with non-conductive paint, including bushings and posts. Guitar has grounding connection to bridge via post near the pots. But, quality of this connection is poor, because paint acting as insulation. I solved this problem by removing of paint layer on the post and also on the place on the bridge, which is touching the post. And, also, this post is too loosy in the thread of the bushing, so I tightened if with small piece of the copper tape into the thread. I also applied a bit of contact cleaner spray to the touching surfaces of post and brigde.
After this, I also did a complete internal shielding by aluminium and copper foil. Now, my guitar is deadly quiet, no hum or crackling noise, even on high gain overdrive channel. It's also quiet, when I not touching the strings. Seriously, I don´t need any noise gate for John Norum Europe type of sound - and this is not common behavior also for more expensive instruments with expensive pickups. I can provide a short video about my guitar after these small, inexpensive, but effective mods.

I've connected a copper wire externally from the knobs to the bridge touching the strings and now It doesn 't make any noise. But i would like to try to remove painting in the places you mentioned so i can remove the external wire. Since i'm not so skilled with Guitar parts, do you have any picture or video of what i've to do to remove painting ? Thanks

Going by michal post, it sounds like the ground connection goes to the bridge post nearest to the controls. If you want to remove the post to check that there is a ground wire at the bottom of the hole, you might find this video useful. It shows how you can remove posts without any special tools. You just need a short bolt that fits inside the post. Obviously, if you do remove the post, you will need to put it back in afterwards. This video shows how to place the ground wire and insert the post. Using a block of wood should avoid any damage to the body of the guitar.
