since i cant afford a new bass that would be worth it, i was thinking about modding my johnson p-copy. i want to keep it passive, and im not going to add another pickup. i love the sound of mia p basses, but im not too fond of mims. are the pickups in these different, or is it just the woods and construction that make it sound so much different? also, would new hardware have a major effect? i see people talking about new heavier bridges and tuners etc., but are they really necessary, or are they kind of frivoulous? besides new strings and a new pickguard, what are some other things i could do to improve my bass?
