On my Essex i am pretty happy with my tone (but i've only played thro a guitar amp) but I want to do more with my sound. Do you think replacing some of the cheapo Essex hardware (bridges, pickups) would augment my sound any or should I just leave my bass alone for the time being? I wanna place an order at Warmoth for a bridge (4 string), maybe a new pick guard, and some new knobs. I might add some pickups if i knew if replacing them would do a lot. Any advice?
