my son and I removed the bart pre from his LPB1 as it distorted all of the time, could not get a clean signal. we used long shaft 500k pots & 47mf caps. the bass sounds as expected. it's one of my favorites, great rock tone.
I'm definitely going to remove the Bart preamp, just to clean sounding with an annoying hiss from the treble. Can someone link me to the right type of pots, I'm guessing CTS Long Shaft Pots 500k and a couple of 47mf caps.

yes, there's a bridge ground. it was a thicker single strand, yellow insulated wire.
