I got it for noodling around, having a super portable bass (the other bass I have is a six string), and just for a different sound to have.
It makes you play different (duuh), also you can reach intervals you couldn't before.
The E and A strings were a little buzzy, so I had to raise the strings (release the truss rod - counter clockwise turns, 90 degrees at a time).
The tuner is great, the preamp seems versatile.
The reason for 4 stars in quality was that the first one I got had a bridge problem - thinner strings sounded wayyyy louder than the fatter ones. I found a fix for it online, but having just gotten the instrument, I went for replacing it and keeping my warranty. People at Thomann were super helpful and in some time I received my replacement and it was great!
It's a lot of instrument, especially for this price. Definitely a recommend
