Or it might just drive you insane. Trust your ears. Notes beat when they’re out of tune. You’ll hear it if you’re playing to backing tracks or drones. If you’re just playing scales you might want the tuner or just check yourself against open strings.Your comment has reminded me that I own a Peterson Strobostomp HD tuner that has the capability of always on pitch detection. I turned it off when I got it but this might be a good time to turn it back on for practice with this baby.
Something I didn’t mention in my earlier post: there’s a fair amount of (what I consider to be) misinformation out there about fretless and I’m pretty happy that I haven’t seen very much of it in this thread so far. The folks who have responded to you are real fretless players who have real-world experience and perspective.
That’s not always the case! I’ve seen a lot of new-to-fretless threads where the answers provided can’t possibly be provided by real fretless players. I’m happy to report that you’ve been given pretty solid, measured advice thus far!
Two topics that I feel are mostly overthought, though, are fingerboard wear and “Mwah.” Some of the theories that surround these two topics can boggle the mind!
Fingerboards will wear no matter what kind of strings you use. Upright basses need to have their boards dressed even though they all use flatwound strings. Frets wear out and so do fingerboards. You should not let this dictate which strings you use (my opinion). Dress your fingerboard if and when it needs it and use strings you like. Don’t overthink it.
“Mwah” is a result of technique. Certain set-ups can help. Certain strings can help. Nothing will help, though, if you don’t have the technique down. Once you do, you will be able to get the mwah sound from any fretless bass - regardless of strings, regardless of set-up. Again, just my opinion. Learn the technique. It’s not really that hard. Don’t overthink it.
Just my few cents…
