Everything has been said on that side.
This is a low with good build quality and I find fairly robust.
The mechanics are great and are good tuning!

UTILIZATION

The handle is actually not too late which is well suited to long fingers!
Access to acute is perfect, not too heavy.
The knobs allow you to properly tailor the sound.
The sound is for me very good (I think it gives its full potential on good solid Ampeg amps or Warwick).

SOUNDS

Great for the Rock, but I think metal to funk and reggae from the ease of slapper ...
The sound is easily obtained and fat is particularly enjoyable on high power amps, the clean sound too.
This is to my mind a character with low well-built (no knobs or rotten making creaky even in the long run it as low on the entry-level) and very strong.
Super value for money.

OVERALL OPINION

I have since 6-7 years!!
I like the quality of construction, its fat is exactly what I wanted.
Initially I had gone to buy an Ibanez because many of my heroes play on but unfortunately I realized what most sleeves were much too thin for my big fingers.
When I tried the yamaha I immediately knew it was this one good!
The value for money and really excellent, prefer such a low used a cheap entry-level new.
I would do without hesitation as the choice she made me service!!
When I change my low, I probably will retry a Yamaha in the lot.
