Description
When you need two full control functions but only have room for one knob position, Bartolini’s DC500kAcd Dual Concentric potentiometer solves the puzzle. It’s a 500K stacked pot, purpose-built for TCT (Tone/Coil/Tap or similar dual-function) wiring schemes, letting you run two independent controls concentrically on a single shaft.
- 500K resistance value — suited to brighter, more articulate passive circuits and active preamp staging alike
- Dual concentric (stacked) design: two controls, one mounting hole
- Configured for TCT-style control layouts
- Genuine Bartolini part, matched for consistency with their pickup and preamp systems
This isn’t a generic aftermarket pot — it’s the exact spec Bartolini engineers around when a build calls for compact, dual-function control real estate. If you’re wiring up a bass or guitar with a TCT scheme and want the taper, feel, and electrical behavior to match what the rest of your Bartolini electronics expect, this is the part to reach for rather than improvising with a stacked pot from elsewhere.
Ideal for builders and techs doing custom control cavity work, replacing a worn factory pot, or converting a single-function knob position into a dual-control setup without drilling a second hole. As always with concentric pots, double-check your cavity depth and knob clearance before finalizing your layout.
