Bartolini TCT Preamps

TCT is the original Bartolini on-board pre-amp. Widely known as preamp used by Marcus Miller, the TCT is legendary. It has vintage FMV (Fender/Marshall/Vox) frequency controls so each band affects the others and if all bands are set to minimum, the output is muted. The TCT is a vintage, complex product for professional use only.

Most of the layouts below are available in active-only or active/passive versions with a push-pull switch on the volume pot so you can quickly pull to bypass the preamp completely. Choose a layout for more details.

Bartolini Preamps come prewired from the factory.

**See the Bartolini FAQ section for information about knobs**
