I got a ibanez bass soundgear gio series, when i move the cable plug in to the plug hole of the bass just touching the plug head attached to the hole, makes some circuitbreaker sound like "toc" toc" i think that perhaps this ciurcuit cables inside the bass makes some conflict or the plug hole system it's meesed up. the other problem it's when i turn up max or low the tones controls of the bass, makes some interference circuitbraker sound only when the tone goes to the max or lowest configuration, i bought these bass used , this bass got 4 years of use previously of mine use, i recently got it. i don't know how to fix this anoying problem, i'll apreciated so much your advices, thanks!

The jack on the guitars is a stereo type jack. The "ring" contact actually is connected to the battery and whenh the PLUG is inserted FULLY it coonects the ring contact of thee jack to the slkeeve contact of the jack which completes the circuit to turn on the battery. Hence while insertying the plug you will firsst get a snap as the tip of the plug ties to the ground of the guitar which is floating and picks up hum. Next the tip will touch the battery connection and get a snap. Finally when fully inserted both the battery is connected as well as the audio.
SOME guitars, especially those with tuners built inj will try tio fire up when the tip (audio) touches the battery cinnection. This may cycle and create the repetitive sound as it tries to start.
