I make no claims to be a virtuoso bas player, but I need a bass for home recordings, and this one is fine for me. Just a couple of points:-
1. I would have expected to find a small piece of polystyrene under the bridge to protect the instrument in transit. I usually find I can loosen the string pressure just enough to slide the polystyrene out without completely dislodging the bridge. But instead with this bass there was a small piece of frayed cotton material which didn't slide out easily from under the bridge, but instead disintegrated into many threads, some of which stuck to the bottom of the bridge, and I had to remove the bridge completely to get rid of them all. Given my rubbish eyesight, it is difficult for me to see well enough to do the measuring to get the bridge back in the correct place.
2. I may be a simple soul, but I would have expected the volume switches on the instrument to be nearest to the thing to which they refer - in other words, volume 1 is right next to treble, and so I would have expected it to apply to treble, and volume 2 is nearest to bass, and so I would have expected it to apply to bass. But no, they are the other way round! I worked it out eventually, but have since found a review of this instrument on Youtube where the guy comments on this and says he thinks it's a mistake. If anyone from Thomann reads this review, could you please check this out? Is this a mistake, or a design feature? In any case, a bit of paper with this information on it would save the customer time in working it out, although, once you know, it's easy to remember.
Apart from these points, I like the sound of this bass, and am happy with it!
