Precision Bass Hum - Hiss

[Bagman]

Hi

 

if the tone pot is dimed , the P Bass hisses when no fingers on the strings

( I never use the tone pot but if I did etc) 

 

I understand this concept with a Jazz Bass , but not a Precision 

what do I need repaired ? 

 

thanks

Hiss is normal.  The source of the hiss is probably your signal chain. 

 

But if by hiss you actually mean hum, then there's a broken earth connection somewhere and you'll need to go through a process of elimination to isolate where between your fingers and the speaker the problem is.

It's hiss , cheers Steve
