I'm looking to add another 4-string bass to my collection. There's two basses I'm looking at and I have zero experience with either of them. I'm a Blues rocker who uses Fender J's & P's. There's a 2013 Gibson EB 4-string with OHSC for $500.00 and a (1999?) EBMM USA Sub 4-string with OHSC for $400.00. I know I have to play each one before forming a purchase decision. Any thoughts on value, price, quality, performance, sound and any other factors? Thank you in advance for your much appreciated comments.
