I bought this bass to replace a Gewa double bass that I had on loan. I have played bass for 6 years and am probably an intermediate student level. I usually play classical with some occasional upright bass (via pickups) for concert band.
It arrived in the week I had requested, and comes without the bridge fitted. It is not particularly difficult to place the bridge (once the strings were loosened) because there is a mark on the body, plus a link to a video to demonstrate how to do it.
I fitted the bridge and tightened the strings round-robin fashion. The G string kept slipping off the bridge so I have to use a slim file to make the groove on the bridge a tiny bit deepe, just for that string.
The sound is pretty good - for the price (£1250). It is quite resonant and has a fairly pleasant tone. The G string can be a bit metallic/ringy, but that could just the supplied strings. My bass teacher gave it a workout and said it is pretty solid.
I have found some notes on the low end (F, F#, B, C) can exhibit a bit of buzz/rattle when bowed hard (ff to fff). In the next year I will probably put the bass in for a professional set up and adjustment (new bridge, strings and height setup).
I plan to use it for the next 8 years. Perhaps when I retire from work I can buy a pro level bass (probably £3K and upwards). According to the Thomann site it is their best selling double bass, and for the price I paid I am happy with my purchase.
