Cascha E-Tenor Ukulele Premium Mah

Fysically ok, but electronic system is one big sh..t. I have become this instrument without battery and and just now can I buy the battery and check how pickup works, and big surprise, but it works not weel. Pickup sensor works only with the first and second string. Third string it's hearing makeby in 50 percents, fourth string only 5-10 %. It was my last order in Thomann! Quaity control don't exist. I was found the same ukulele in Germany with 25 % lower price and with tuner and plectrums, but said me, that it's better to buy it at Thomann, I was really wrong meanig! Never again.
