I'm thinking of purchasing a double bass but I'm not sure if I am doing the right thing. My background: Many years playing the electric bass from rock & folk to jazz & fusion. But that was 24 years ago. I stopped playing because I became a TAFE teacher (that's a community college teacher) and there was no longer any time to play or to do anything else for that matter lol. When I stopped I was really playing Jazz & fusion and that remains my main interest to this day. I have now retired and last year bought an NS NXT as it seemed to be an instrument closer to a double bass than my 70s fender precision which I still adore but rarely play (it's those fret things...they get in the way). I have been relearning everything I have forgotten out of my old copies of Rufus Reid and Ray Brown and although I know the NS does not a double bass make playing it is totally different to the electric and I have tried to be faithful to the double bass fingerings foir this instrument. I bought a bow for arco and went to lessons pretty quickly as my playing was awful (ok it's still awful but everthing is relative lol) and he immediately latched onto my left hand like (OMG what are you doing) and I started again. There are thumb positions? Who knew? Somehow I'd totally missed that. So I'm slowly making progress to the point where I am wondering if if I should bite the bullet and get a proper double bass. However: I'm almost 60 years old. I have arthritis in both thumbs (not due to playing and playing the NXT has not made it worse....might have actually made it a bit better) I'm not very strong physically....like any 60 y.o. woman my body is prone to not doing what I wanted it to do lol. But I do listen to it, I don't overpractice & take plenty of breaks etc The thing is I love Jazz, especially latin rythms and I love that big beautiful double bass sound. But am I deluding myself that I could play "the real McCoy" without injuring myself. I'm seeing a Luthier next week to talk about double basses, see what they have and try few things out. That's Altier Puglisi for those in Melbourne Australia. Honestly you guys overseas are soooo spoiled for choice. We are lucky if there is one luthier available to us and they have a very limited range. Which gets me to two fundamantal questions. What should I be looking for, not so much for the bass itself but for it's playability by an ageing body and (question 2) I notice they they have a Czech Ease. I've read the reviews here and they are not entirely positive but I'm looking at it's weight. I would not be happy with a crap instrument period. I might be inexperienced but my musicality is quite good from past playing and a poorly playing instrument would just frustrate me. I guess I'm looking for something I can play, sounds great but won't kill me. Any advice at this point would be dearly welcomed.
