If you are a beginner you should go for a Squier, they have many great basses, like the P Bass Special Black or the Vintage Modified Precision Bass, which is a replica of Sid Vicious.
Or you could search for Fender Jazz Bass Special, the bass that Duff mostly uses, and you could get one pretty cheap, i have a Fender Jazz Bass Special in super condition and it's fuckin' great and the best bass i ever played on, the bass weights nothin', it sounds awesome..and the neck is super comfortable..
Or else you could go for a Epiphone bass, like the Thunderbird..but it's very unstable..
Ebay is your best friend
good luck in search for your new bass!
