I recently purchased a used Yamaha RBX170EW, mango facing from Guitar Center for $130.00 in pristine condition, like new. I understand these are very inexpensive basses. I was searching for a p/j bass and stumbled upon this bass. I replaced the rw strings with rotosound 77 flats. I have been playing it for a couple of days and I must say I am impressed with the playability and variety of sound/tone that it produces for such an inexpensive bass. Just wondering if anyone out there has experience or comments regarding this model.
