Nickel

I do not own an acoustic guitar so for some unplugged tones, I have my Ibanez AF105 to address my needs.

Everything's great with this guitar less the humbuckers it's equipped with- no, not the tone but the fact that it's nickel plated. Nickel will oxidize/ fade over time (as depicted above) to give you that wonderful vintage look but you can't restore the shine with the common metal polishing fluid/ cream. This relic effect will be accelerated if it comes into contact with chemicals commonly found in industrial glue.

You'd be wondering why your nickel plated hardware fades off rather quickly when all you do is keep your beloved instrument in its hard case- that's because it comes into close contact with your case's inner lining & 'digs' into the furry material, leaking the glue that binds it to the shell. That's why...
