Well one of the springs of the tremolo has come loose .it happend before when i was playing and then i just put the spring back but now i wasn't doing anything .
My guitar just stood in my room and the spring went loose.
I don't know what 's causing this and how should i best fix it so it won't happen again.
well remove the other end of the spring from the trem block. then reattach the circle end of the spring onto the trem claw and you need to be very safe here and re-insert the other end of the spring back into the trem block, you may find this easier by slightly loosening the trem claw.
