Here’s some of my musical instrument mistakes.
This was an Ibanez bass I returned a couple years ago. It buzzed and didn’t play well. I had it set up, and it still buzzed. It was brand new and still junky. I sent it back.
I tried to buy an acoustic bass for practicing and because my teacher was offering in-person lessons to players of acoustic instruments. This weird-looking thing is a Traveler bass. It was horrible to play and it wasn’t an acoustic (although it was advertised as having a great acoustic sound). It got sent back.
This was a better made, actual acoustic bass guitar. A Guild Jumbo Junior. I didn’t like this one either, and I decided an acoustic bass was not for me. This one got returned, too.
I also tried a five string bass. This was a used Yamaha RBX775. It was described as being in excellent condition. When it arrived, it had what looked like moldy spots on the tuning pegs, and it was very dusty. It looked like it hadn’t been well cared for. It also had a loose selector switch on it. I didn’t like it enough to have it set up and repaired. It went back, too.
They’re not all winners.
