I'm not sure what to do. I have a bass teacher now that is actually a guitarist, he has a mumbling issue and talks a little fast but he is the nicest teacher I've had on any instrument. He thanks me for working and is very encouraging. I like him a lot as a person. I met another bass teacher today. He is a lot younger than my teacher. Has a different attitude but seems nice. He also actually plays BASS. This was apparent when he asked me where I played on the fretboard. I did not know that I was supposed to play in a different part than I was playing. Is there that many differences in teachers that play two different instruments? Should I switch teachers?
