I just got an old Ibanez ST980 8 string bass for 5 bucks on the side of the road. Why? Because its completely gutted and defretted (amateur job of making it fretless) and was told the neck was warped..I want to make this into a 4 string. Can I put a cheap replacement neck on it? I don't know about scale/ neck pocket.. what can I do about fitting pickups on it? Can I fill in the bridge and just slap a p bass style bridge like my Squire? I want to make it a bass on the cheap!! Any help would be great!! Thanks!!
