    yes, plugged the git into my homemade 2 watt amp and no buzzing, so i think i've a fault with my 10 watt practice amp,, thanks for all the info everyone,,

    i knew joining this group would yield bountiful information.

    Good reply Eric.   

    Sometimes the jack frame and ring/tip solder connections can fool one if you are looking at it

    visually. Usually,  the frame of the jack is last " end terminal" and has a visible connection.

     If the jack has a ring connection and tip connection as well, those could be interchanged

    and that could contribute to the buzzing.  

    For troubleshooting grounding issues, I have found that soldering a temporary wired to the jack

     frame (the actual ground lug) and touching the various spots where the shields or ground wires

     are supposed to have a connection to the jack frame..will help in troubleshooting.

     If the buzzing stops, you have localized the area of the problem.

    Garage Hermit, double check the wiring on your jack to make sure you haven't wired the jack backwards by mistake.  Buzzing when you touch the strings sounds like the strings are wired hot.

    Perhaps your string earth isn't contacting? Touch the strings to get the buzz, and touch the earth of the jack with your other hand, does the buzz go away?  If it does, your earth is good, but not connected to the strings.

    To check the whole circuit at once, (lead and all), plug a lead into the guitar, turn volume control on the guitar to max, and check for continuity between the earth of the exposed plug (the long base section, not the tip) at the amp end, and your strings.  If there's no continuity there, then check the same from the tip of the jack to the strings - there should be no continuity here with the volume on max, but there should be continuity with the volume on zero.

    If you find problems when you've checked globally like this, then test smaller sections to pinpoint the problem.

    Good Luck

    Hi,

    I was interested to read this as normally any grounding problem gets better when you touch the strings.  Had a quick look on google and found this http://www.guitarnoise.com/forums/viewtopic.php?f=3&t=42896

    Any chance the wiring is reversed?

     

    Regards,

    David

    I don't know much about wiring but how are those wires connected at the pots? It looks like tape is wrapped around but how secure is the wire-to-wire connection?

    they're all soldered, tape is just insulating the joint's,,

    have you tried lowering the pup away from the strings?

     

    not yet, i'll give it a go, thanks
