Looking for a guitar tech

[Can samui]

Hey folks.

Old dog here trying to learn a new trick, bought a decent electric guitar but it needs an experienced player/tech to give it a once over as there is some string hum through the amp.

Would love to hear from anyone who could help out.

Cheers

What kind of guitar and does the hum go away when you touch the strings ?

Yamaha eg112 and yes, it gets quiet when I press the strings.

Missing earth connection – when you touch the strings, you become "earth" – in old time Europe a wire to a heater (hot water heating system with metal pipes) would limit the hum, however that's not a common solution at Samui. Another weird old trick for valve amps is to reverse the mains plug, which often reduce the hum, but won't eliminate it. I've seen guitar players with a copper wire connected to the guitar in the plectrum hand – or tight around the wrist – which also can work...

Muchos gracias khunPer!
The amp had a ground spot but no prong so made one out of an old aluminum license plate holder and it works the bomb!
Silent as a bunny until I i inflict pain upon the strings.
Many thanks.
