Stefan’s solo model is just fantastic!
I own his Kaagstein model which is 5 string bass and I really love it. So I ordered his solo model for playing solo. It’s much smaller than 5 string model but unbelievably it’s lower string sounds same as 5 string bass. Very profound, warm and powerful. Of course high strings sound more bright. Stefan’s basses have got the same quality of tone which I really love.  Thank you Stefan!
