My main P bass since 2007 has got a fair few chips, dings and scratches all over. I remember being really miffed at the first blemish.Now as long as it doesn't affect playability I'm not too bothered. I do like to keep it clean though. Cufflinks and metal cuff buttons on a gig jacket meant I had to actually sand smooth some of the worst on the forearm chamfer.
Now it's all actual real life mojo wear but in comparison to the finely crafted fake wear on a high end relic it looks like a half arsed ebay special!
