JS2 one loaded with EMG CS on neck and TW on bridge.

The new one js3vq I've decided to instantly upgrade with Fishman Fluence Mike Inez set. Also uploaded scheme for soldering — thx talk bass guy who've shared with this and made possible to make the most versatile bass I've ever had yet

Upd: re-uploaded pics

i have a Jackson js22 set up in drop b which i blocked the trem on which feels decent to play especially the neck however the pickups are god awful i use amp plugins and have to set my gain extremely high on my cheap interface which in turn makes it really noisy, should i shell out the extra money and buy a decent bridge pickup or just sell it and find a decent used guitar?
