Description
Wiring in an active preamp shouldn’t mean losing the personality of your bass — it should mean unlocking more of it. The Bartolini XTCT is a straightforward 3-band tone control module built to give bassists serious shaping power over the low, mid, and high end of their signal, without demanding a rebuild of your whole electronics cavity.
What sets the XTCT apart is just how far you can push it. The boost and cut range on all three bands is wide enough to recall the tonal reach of those classic old Fender amps with separate Bass, Treble, and Presence controls — think low-mid warmth that can go from tight and woody to full-chested and round. The 500Hz mid-cut point specifically targets the frequency range that defines a lot of a bass’s character, so you can carve out mud or dial in aggressive honk depending on the song.
Runs on standard 9V power, making it a practical swap for players who want more control on stage without adding a rack of outboard gear. Whether you’re upgrading a passive bass that needs more tonal flexibility, building a custom instrument, or just tired of a one-dimensional stock preamp, the XTCT gives you a genuine 3-band EQ setup to shape your low end exactly how you hear it.
