Whn i plug the cable into the jack all the way there is no sound at all

But if i pull it out a tiny bit the sound comes through but is weak as hell

Have I pushed the jack into hard or something?
Its my ****ty mg that im using for practicing with atm

I have other amps though so dont start a get a new amp thread
If you don't really care about the amp, and it's easy to open up, no reason not to check out the wiring.
