Re: Dimarzio Clip-Lock Damaging Guitars?
A +1 vote for the DiMarzio Cliplock's (have used them exclusively for 15+ years), but I will confirm that they can indeed damage your finish if you're careless with them. You also have to be aware of where the plastic clips are when you close your guitar case.
However, I've not had problems with this over the years. Of course, I've never owned an Ibby worth more than about $1k. I might think twice about the Cliplocks if I bought a rare model or, say, a J-Custom. Even then, I might still go with a Cliplock.
I've tried the Schallers too, and they're excellent, but the amount they stick out bothered me, so I went back to Cliplocks.
