Harley Benton Enhanced MJ-4EB Lake Blue

After buying a previous HB bass, I thought i'd upgrade to an enhanced model.
Unpacking left me impressed. A good looking bass with a great finish.
Jack socket loose and one screw missing. Hmmmm...Sorted that.
Volume pot felt cheap. Cover pulled off when engaging passive mode. Glued back on.
Balance pot not at all smooth.
Plugging it in left me less than impressed. Very buzzy when not playing. Poor tone.
Very effective EQ section. Huge tone changes
For some stupid reason I opted not to return in. In hindsight I wish I had.
I'm now left with a bass that looks ace, but in reality is ungiggable due to the buzz when not playing.
If I buy another bass, then I will definitely buy with my ears rather than my eyes.
Maybe I just received a duffer, but apparently it had been "checked" before despatch. I can only imagine that it wasn't plugged in!
Disappointed....
