I was a bass player when I was still active in the local music scene. I put some of my music on steem in the last couple of years, but I have yet to put any music on hive except an old video from back in the day. I had to get that from the youtube channel of the guitar player that I worked with for many years, he has all the video stuff that was taken of the band back then.
My amplifier for most of the 20 years that I played live was either a Fender Bassman 50 watt, or a Fender Bassman 100 watt, depending on the venue. The speaker cabinet was either a Fender 2X15 cab, or a Musicman single 15 cab.
My first bass was an inexpensive one, the second one was a Musicman Sabre bass, and after that I used a Gibson Q-80 bass which I still have. Toward the end of my live playing days I also used a Peavey Patriot bass, which weighs less than the Gibson.
It's my guess that most old bass players have a bad back...
I still play the Peavey when I do recordings of the songs that I've been working on.
