Mine was faulty, one of the stacked knobs (tone) worked intermittently. Thomann was very nice about it and the bass is on its way back.
Apart from this minor issue which could certainly be fixed easily, it is a great bass, that sounds great, with a great preamp. Two downsides though: I suspect the tone in passive mode does not do a lot (but it may be because mine was faulty). And it is heavy.
