Been looking at the Ibanez SR500 , SR500PB and the Yamaha 504. An ESP D4 used bass just came up that is in mint condition. I know absolutely nothing about ESP as a guitar manufacture as far as quality and sound. If anyone has any experience with them, please feel free to share. Not sure if I like the two tone wood stain running right through the body. How do you think this compares to the SR500 or the Yamaha 504
