Description
Most active systems treat a dual-humbucker bass as one big signal to shape. The Bartolini TQB 918 takes a different approach: it buffers each individual coil separately, before they ever get combined at the pots. That matters because passive coils loaded down by pots and switching lose top end fast — this quad buffer gets ahead of that problem at the source, so your blend and tone controls work with a signal that’s already clean and strong.
- Runs on 9V or 18V power
- Buffers each coil independently in a dual-humbucker configuration (four buffered channels total)
- 270 ohm input impedance keeps loading light on your pickups
- Low output impedance for a crisp, articulate feed downstream
The result is a bass tone that stays detailed and present even after everything gets mixed together — no mushy low mids, no disappearing highs when you dial in a blend. If you’re building or upgrading a dual-coil bass system and want the electronics to get out of the way of your pickups rather than compress or dull them, the TQB 918 is built for exactly that job.
Ideal for players and builders who already know their coils are good and just want the wiring stage to stop robbing them of clarity.
