It's obviously a very testing time for everybody, and to try and help out I see that Zoltan Dekany (monster electric and double bass player as well as being a superb tutor) has made all of his courses and lessons free for the next little while. They're all on his bass education website https://www.zoltansbasslounge.com/ and there's material for electric bass and double as well. Like I say, he's a great tutor and his double bass courses gave me a great start to what was a new instrument to me.
