I was out looking at basses a few weeks ago and couldn't beleive the prices stores were asking for modded basses. IMHO some basses just shouldnt be modded. The obvious one here would be the 4001/4003. I never understand why people change the bridge or the pickups on those. Just sell it and buy the bass that has that hardware?! I should be one to talk, I have modded a few of my own. But for the most part I just can't see the logic behind some of the mods I see.
