Description
If your Thunderbird’s stock pickups are muddying up the low mids or losing clarity when you dig in, this Bartolini T4CBC set is built to fix exactly that. It’s a direct-fit soapbar replacement for Gibson and Epiphone Thunderbird 4-strings, so there’s no routing or modification needed — just swap and go before your next gig.
These are part of Bartolini’s Classic Bass (CB) series, voiced for an extended, more resonant frequency range than a typical stock pickup. The blade magnets are CNC machined for consistency and covered in epoxy to keep things dead quiet — full hum-cancelling operation, no hiss or buzz creeping into your signal chain.
Width-wise, the blades are cut to comfortably cover string spacing from 50mm to 59mm on medium spacing, so they’re sitting right under the strings for even output across the board.
Tonally, this is where bassists notice the difference: the low end stays deep and full, the low mids keep their weight, and the top end opens up with more definition and pick/finger attack coming through clearly. You’re not sacrificing the growl for clarity, or vice versa — both live together.
- Direct replacement for Gibson/Epiphone Thunderbird 4-string soapbar pickups
- Bartolini Classic Bass (CB) series voicing
- CNC-machined blade magnets, epoxy coated for hum cancellation
- Covers 50mm–59mm string spacing (medium)
- Extended frequency range for deep low end and articulate highs
A solid upgrade if you’re chasing more low-end character and top-end clarity out of your Thunderbird without touching a router.
