i searched as much as i could and this didnt seem to be addressed in any of the common grounding problems questains. so here it goes. i recently purchased a squier vintage modified 70s jazz and i love the tone when the tone control is set so that it is trebley ( full on?) but i get a horrilble buzz when i am not touching the strings or metal on the bass etc. when i roll the tone knob to get a bassier tone the hum/noise goes away but i lose that trebley tone that cuts through so good. i already compared the wiring to a schematic and it SEEMED to be correct and i checked that the ground wire was under the bridge properly. does anybody have any ideas or experiance this? is it something i have to deal with or would sheilding help? o and by the way i have both pick ups on full volume all the time. thanks ahead of time to any responders.
