I have wanted to learn to play double bass for a long time. I played piano when I was a kid and I don't regret it, but it wasn't my choice of instrument. It was my mother's. I'm in my 50s now, but that desire to learn the double bass is still there. I have found a local shop from which I can rent a 3/4 double bass. My budget is tight, but I think I can swing the rental fees. I am renting first because I worry that I won't like it as much as I picture it in my head; the idea of it versus the reality kind of thing. Okay, that's the background so now for the questions. 1. Finding a teacher right now is not a good idea. Due to health issues and age, I'm at higher risk from complications should I contract covid-19. I know it's not ideal, but will learning from videos and information on the internet provide enough foundation? 2. Rental of the double bass comes with a new set of strings and a bow. I wish to learn rockabilly and swing. One source of information I found said they use a hybrid setup for their action to be around 7mm for the G string. Is that about where I should be asking the shop to help me set the action? And would that be about the same for the other strings? 3. And also, do I just use whatever strings they might put on the bass to start while I'm first getting started? Or should I try to get them to put on Slap Happy Weed Wackers since that is the style of play I am wishing to learn? If I go with the Weed Wackers, as a new player should I be getting the standard gauge or the premium gauge? Any other advice or suggestions you might have for me would also be appreciated. Thank you for your time.
