Hi there
i currently have a 2008 Mayones Jabba 4 with modded circuitry. At one stage I think it was an active bass and was converted to passive, it sounds great but a little ‘dark’ (ie not much top end “zing”. I wonder should I replace the Delano pickups . I’m guessing these were designed with an onboard preamp in mind .. the capacitor is “normal” as far as I can tell .
