I have been playing bass for 25 years but decided to try fifths tuning for about 5 years ago and haven't looked back since. It opens up the sound of your instrument, makes intonation clearer and makes you able to play new things that no other bass player can do on a normal fourth tuning instrument. Try it! I can also teach you left hand four finger teqnique and right hand three finger teqnique(if you're right handed!). I usually work using standard jazz repertoire but we could also work on your classical repertoire or whatever you choose. Text or call me!
