Dnj is right! There's a bass player here who uses an old Kay...cracks all over the place, plywood construction...patches and strings about one inch off the neck. He can blow me off the bandstand, Zeta or imported Austrian bass not withstanding.
There's also an old guy playing an M-3 that has to be hit two or three times to get it working. A terrible instrument! In his hands, he also can blow me off the bandstand. (Hey, see a pattern here?).
The "pro" certainly is the player, not the instrument.
That being said, I bought a PSR 3000 and decided I didn't want to use it for my professional work...gave it to my grandaughter.
It's all about what you like and what works for you.
