Epi makes a number of different models of Thunderbird.The "regular" TB IV is the bolt-on model, which I'm ashamed to say I blew off & laughed at for years... until I got one. Considering they can be found on the used market pretty regularly between $150 - $300, they're a
steal! The Classic & Classic Pro are both neck-thru models, and remarkably close to a Gibson in terms of quality. The Classic Pro has an active system. I'm not an "active" guy, and have never experienced one in person, so I can't offer much intel there. The Classic comes stock with Gibson pups, and in a double blind test... I'm not sure you'd be able to tell the difference between the Gibson & the Epiphone. The newest one... the Vintage Pro... only started trickling out onto the market within the past couple months, and I've yet to see a bad review! People who've been playing Thunderbirds for 40 years, and people who've just purchased their first 'bird, both agree that the Vintage pro is an incredible bass at
ANY price, and strongly recommend them! Regardless of what 'bird you eventually plug in... the most important advice I can give is this: If you're used to P's & J's and the likes... do not expect to sit down & plug in at your current amp/fx/EQ settings, and expect it to make the sound that you're used to hearing. The Thunderbird is a different animal. Generally speaking... they're mid-forward, and produce a snarl without the aid of external devices or a jacked up pre amp.
I'mma stop babbling now, but will extend an invitation to stop by the Thunderbird Club. There's lotta knowledge & experience from a lotta people more qualified than I, to answer any questions you might have. Probly get a laugh or two as well!
