Thank you very much SpondonBassed,
I guess it was about 33 years, that I didn't play bass... what a pity, but I was young, started a new life after school, left parents home and everything changed. Especially that I hadn't no more time in the afternoon and with changing friends Ilost my band and so I stoped playing.
In the meantime I started to learn marching drum (for the Carnival of Basel, which is now "Intangible cultural heritage" of UNESCO), and I practise it now for more than 20 years. But I like playing bass. Its like coming home...
But I would apreciate to know other bassists in my region, to exchange experiences.
