Really bad experience with this. When first settingit Up, like another reviewer on this I didn?t clamp it correctly, the whole upper assembly slipped sideways and my bass fell off, causing a fair amount of damage to my beloved instrument. How come I didn?t clamp it correctly? Well, I looked at the instructions but they were only in German. Come on guys, if you?re going to ship internationally, this kind of document should at least include English as a more widely-used international language. It?s a well made piece of equipment but it?s going to take a long time before I trust it again. And my bass will need a trip to the luthier before I can use it again.
