Ok Frankie, time for some bass guitar talk...

I mainly play guitar , but I have an esp (not ltd )
J4 bass . A lot like a jazz bass thin neck . I love it easy to play with the right amp it thumps.
I don't know much about bass pickups ?
All my guitars have different pickups one active the rest passive.
Emg, Seymour Duncan , and dimarzios .
I have an old fender bassman amp , but it's been modded , effects loop ,
And master volume with more gain .
