求救一下电路问题!!!!!!!!!!!!!!!!
我买了一把二手电吉他PRS SE SANTANA，后来发现了吉他上的VOLUMN 全开没有杂音，半开反而有有明显的杂音。琴是二手的所以有可能给重焊过电路也说不定。在一些外国网站找到一点线索，但我是外行人看不太懂，想请问有那位师傅可以详细解答一下！谢谢Is the hot wire from the lead pickup wired to the first lug of the treble volume and the hot to the switch coming off of the center lug?
The volume will work with the hot leads reversed, but it won't ground out the cable when turned down, so as you turn down the pot the signal to noise ratio gets worse.
Correct that, with the pickups to the clockwise lugs and the switch leads to the center lugs, and you'll get better volume control and likely fix the hum problem, too.
Basically the Hot wire from the PUP and the Selector Switch wires need reversing on the Pot tags(Move capacitor wire as well if attached there).
内容好像说什么拾音器PICKUP的火线跟切换SWITCH的线接反了，音量旋钮一样能正常工作，但你关小音量它就不能接地，导致噪声变强。
你把情况复杂了，更换B500k音量电位器即可。 那堆英文哪里搬来的 ？
内容是如果你半开了就会有噪音，需要把Pickup 的线焊去电位器左脚，档位器的线焊去中间的脚就可以解决 ～
可不可以就不知道了 ～ 你试下吧 ～
