Nice bass. I have a 2017 in red. The stock rounds were not so great for it of course.
I tried the La Bella LTF medium scale and Pyramid gold flat short scale. The latter just barely fits. Intonation was a little problem. I would have to notch the D and G saddles to get them back quite enough as the post gets in the way.
La Bella LTF sounds very nice right out of the box, that warm smooth plunky sound somewhat like a double bass. Pyramids took a little break in to get rid of the excess twang on the G string. They have a bit more “hair” on the tone vs the LTF, but very warm and smooth. Especially with the Pyramids you can hear a lot of those old Phil Lesh and Jack Casady tones. The hollow body gives it a throaty sound even with some overdrive.
I like the neck pickup on full a lot, lots of dynamics, and set up the bridge pickup with tone well rolled off to get a more mellow sound just by switching the pickup selector. It’s a bit too many options but I’d recommend getting the two pickup version because the neck pickup sounds great.
