So I now have two US Professional Jazz basses. My first has a maple fretboard and whilst I really like it it was a tad difficult to tame the top end, even strung with nickel rounds. So I bought one with a rosewood fretboard, and even though this one is strung with steel rounds the sound is much more even across the spectrum. Was fully expecting to have to take the steels off as they’re usually much toppier than nickels but no, they’ll stay. I went down this route as I saw a clip on YouTube comparing 2 Jazzes from the same range, one maple one rosewood and I preferred the sound of the rosewood one. Am glad I did, the new one is much better for what I want at present.
