I’m a subscriber and received the following email:
In the midst of the Corona virus pandemic, we have decided to show our support to our valued members and have switched all courses to free access. As we are mostly "stuck" at home for the next while, we want to do our best to ease the burden and help you spend some of this time productively, practicing your instrument aided by every course and lesson we offer at zoltansbasslounge.
There’s six courses for double bass and two for electric at beginner to intermediate levels.
Enjoy!
I will soon be starting my one-man band after completing all these free musical instruments lessons.
