Indeed, it's a perfect fitBy the way, GHS "universal long scale" with 37.25" winding length (ball end to silk) should be long enough for Yamaha's diagonal thru-body design.
I love the Boomers on my BB424, their rich mid tones nicely join together the sounds of the P and J pickups, giving a sound that's rounded and full, but still lively. This bass will never see anything else!
