3-Band Tone Stack

Utility board to add a TMB / FMV 3-band tone stack to another circuit.

We've included an optional (but really, go for it) FET recovery stage to make up for signal lost to the stack, since it's a passive/reductive affair. Simply wind up the volume trimmer until the stack sits nicely in the circuit.

We're only including a couple of different variants right now. We may add more in future. Feel free to grab a PCB and come up with your own tailor-made version using the Duncan Tone Stack Calculator.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.
