Description
If your bass pickups are on the quiet side, the Bartolini TC3 is the straightforward fix. This discrete preamp/booster is dialed in with a preset minimum gain of 12dB right out of the box, so you’re never starting from nothing — and when you need more push for a solo, a slap passage, or just to match a hotter-sounding rig, you can dial the boost up to 40dB.
- Discrete preamplifier/booster circuit
- Preset minimum gain of 12dB
- Boost adjustable up to 40dB
- Designed for low to medium output pickups
- Runs on 9V power only
This is the kind of unit players reach for when a bass just isn’t putting out enough signal to compete — think vintage-style low-output pickups, passive basses that feel thin next to the rest of the band, or any setup where you want more control over your own volume and drive before it hits the amp. Because it’s discrete rather than op-amp based, the TC3 keeps things clean and true to your pickups’ character while adding the gain you actually need, instead of coloring your tone into something else entirely.
It’s a simple, focused piece of electronics — no EQ knobs to fuss with, no tone-shaping decisions to second-guess. Just gain when you need it, built to install into a bass and stay out of your way. A practical upgrade for anyone tired of turning their amp gain all the way up just to get heard.
