Switched over from Tuba to Bass a year and a half ago, and im looking for something more Bass wise. I have my old Ibanez SR 300 and am looking at the Epiphone Thunderbird "pro" 4 or a Fender MIM J bass. "Bass"ically Iam asking your opinions on said basses, and prehaps suggestions on others, looking to spend ~600 ish!
