Tools get battered and abused. The amount of times I've bought a brand new mechanic's tool and the first time I needed it I had the nastiest hands possible are infinite. If you work your gear, regardless if it's bass gear or whatever, wear signs will show soon enough.
As long as everything still plays I don't care about dings, dents or scratches too much. If one is new to me, I'll inspect it, but I don't feel no type of way.
Back in May I played a big festival and ended up using my work van to carry my rig and basses to the festival. I played my SR305 for one set out of six. When I got it home, I realized I must've sat it in the van wrong. The bass knob is bent, and cannot be turned, so my bass boost is where it's at haha. It'd be a problem if I didn't like the setting, but I do, so I am in no rush to fix it. But I was a little bummed when I saw that I did that, for a total of about 2 minutes. It still played and sounded the part, so meh, rocking the bent knob.
