4-String Original Bright RT Soapbar – RT4CX
Retail replacement pickups for Tobias Classic and Killer B basses.
$185.00
Refine and elevate your sound with the Original Bright Soapbars – designed for bass players who want a brighter, more articulate voice while keeping the depth and punch that Bartolini pickups are known for. These pickups still deliver plenty of rich lows and powerful low-mids, but with a crisp high-end that cuts through the mix.
With a higher resonant frequency and a smoother peak, the Original Brights have a balanced output and a flatter frequency response. The enhanced treble introduces more phase shift at higher frequencies, adding complexity for an aggressive bite and growl. They are punchy and precise, delivering a modern tone that complements your bass’s natural voice. Prominent bass builders have long used the Original Bright voice, especially with an on-board preamp.
Structurally similar to our classic Original Soapbars, the Original Brights ensure clarity and definition in every note. Each pickup is fully shielded and sealed, making them resistant to sweat and noise from stage and studio environments. Shielded cables add extra protection for a flawless performance.
Available in balanced versions for the neck (Bass, -B) and bridge (Treble, -T), the Original Bright Soapbars are your go-to choice for a modern, dynamic sound that stands out.
