I have an Ibanez BTB 780PB in charcoal brown with a serial number that starts with 08...so I guess it was made in 2008? Anyway, for some reason this bass is not in any old ibanez catolog online that I can find. They have the 775 which is a 5 string buy mine is a 4 string. Anyone have this same bass? In descriptions online where the bass was for sale it says it has a Fishman Piezo bridge pickup....how can i tell if mine has it?
