Plug grounding

Managed to ground another plug yesterday. For those of you who wish to engage in this DIY procedure, a sharp wire cutter really helps & a wire stripper if you can't utilize the cutter as one.

3 pin vs 2 pin

You're still wondering where's that background humming/ hissing's coming from after you did well to shield your guitar's electronics/ cavities & switched to low-noise/ noiseless cables- it's the power supply plug (PSP).

In the pic above, the left PSP is utilizing a 3-pin plug. The extra pin is an earth pin, it grounds the equipment but more importantly, it eliminates humming for your amp. The PSP on the right, sporting a 2-pin version, can be converted into a 3-pin make; simply purchase a 3-pin plug from any electronics/ hardware shops & do the necessary replacement (you know nuts about electronics- then get someone else to show you; it's a simple replacement really...).

Your radio/ computer's using the same 3-pin cable plug- could it be used, then? Of course...

At the end of it all, it's a futile effort to simply check for noise leakages from your cables & guitars but ignoring the amp's grounding...

NOTE: This plug replacement CANNOT cure the single coil (pickup) hum...
