Is there an aftermarket direct replacement tremolo that will fit a Sterling JP150? I've tried every trick in the book and my Sterling JP 150 will not stay in tune whatsoever. So disheartening!
My experience with SBMM instruments (I've owned close to a dozen over the years...), is that the higher end, say around $600 and up, are usually decent quality. But most of the entry level guitars are disappointing... again, that's been my experience.
But their bass line is a different story.... I've had a couple of Ray 4's were were surprisingly good....
