I've got a basic Yammy Attitude Plus bass that sounds decent through the Hartke 2000, TP 210 and Ashdown Mag 115 cab but the highs are lacking and the lows are a bit muddy. I'm wanting to do a pickup swap and I think I've narrowed my choices down. My question is with the bridge. How would swapping the POS stocker with an aftermarket one affect the sound? Recommendations are a plus. Any suggestions on pickguard material? I kind of like the white on black and thought white pearloid would look nice. Any other ideas on mods would be great! Oh...don't mind the cat!
