Newbie in here so maybe what I am dealing with is a completely normal thing but... I have a second hand Rickenbacker 4003 from 2011. Ex owner said it passed a revision before coming to my hands. Bought an Orange 25W amp, new. Bought a 10 USD cable. Now, cable connected to the standard output, bridge pickup in work, bass and treble tone slightly opened, bass and volume at its half power and annoying buzz which dissapears when I place any finger in any string or besides the standard/rick-o-sound connection. I just have to give volume to the max to the treble volume and that buzz dissapears. Crappy cable or worst thing going on? Help!
