Description
If you’ve ever wished your bass had that classic old Fender amp voicing — Bass, Treble, and a low-mid Presence control — the Bartolini TCT gets you there and then some. This 3-band tone control module drops into basses (and guitars, if you’re into that) and gives you serious range to shape your low end, sculpt your mids, and dial in top-end clarity.
The star of the show here is the 300 Hz mid cut/boost. That’s the frequency zone where boxiness and mud like to hide, and where honk can creep in on a stage full of other instruments. Being able to pull it back — or push it forward for more growl and presence — means you can carve out real space in a mix without fighting your amp EQ all night. Pair that with wide-sweeping bass and treble controls, and you’ve got a preamp that can go from vintage warm to modern aggressive with just a few tweaks.
Built by Bartolini, a name bassists trust for pickups and electronics that actually translate feel into tone, the TCT is a solid upgrade for anyone looking to get more tonal control out of their instrument without changing pickups.
- 3-band active tone control: Bass, Midrange, Treble
- 300 Hz midrange center frequency for boost or cut
- Wide tonal range comparable to classic Fender amp EQ sections
- Full wiring instructions available from Bartolini
Whether you’re gigging, recording, or just tightening up your tone at home, the TCT gives you the low-mid control that so many stock preamps leave on the table.
