The Varitone Circuit Demystified: Scott Sharrard and the ...

    Essentially the Varitone is a variable notch filter, except for Position 1 (P1) which bypasses the Varitone completely. The player can imagine a flat equalization for P1, and then imagine a relatively small dip or notch at the upper frequencies for P2.

    For a completely passive circuit, it provides a decent pallet of tonal changes on both electric guitars and bass guitars. The original Gibson Varitone is a bit different in that it uses both caps and resitors and a 1.5 Henry choke. A 1.5H choke is rather large and heavy physically and not readily available.

What is "Varitone"? - inSync

    https://www.sweetwater.com/insync/varitone/
    Introduced by Gibson in 1959, the Varitone 6-way tone control is a circuit that acts as a notch filter, reducing frequencies at set points along the frequency spectrum. Filtering is achieved by passing the signal through capacitors that effectively remove or reduce specific frequencies. As the Varitone knob is rotated from positions 1 to 6, the center frequency of the …

*UPDATE* Gibson Varitone Replacement Inductor? | The Gear Page

    A varitone is a simple series resonant circuit, the resonant freqs for the 1nF,3nF,10nF,30nF and 220nF cap settings would be approx 4.1kHz, 2.3kHz, 1.3kHz, 750Hz and 277 Hz. If the inductor was in the microhenry range, you'd be looking at series resonant freqs far above the audio band.

    Again, I dunno. Gibson went through the trouble of using a humbucking inductor. But Varitone clones made with unshielded audio transformers are tolerated today.

    This is for a standard Gibson 6-position Varitone: Position 1--> off Position 2--> -5db at 1950hz Position 3--> -12db at 1100hz Position 4--> -16db at 620hz Position 5--> -18.5db at 360hz Position 6--> -21db at 120hz Position 5 used a .03 cap. The L-6S guitar used a pot instead of a switch, and a .01 cap.

    audio frequencies than a 100mh choke, I would think. Maybe this doesn't make that much difference. in a guitar tone circuit, and you get a range of frequencies anyway.. but would the range of frequencies made with any audio transformer, be the same as with the original Gibson engineered varitone?

    You can use an audio transformer like this for the choke (inductor): Mouser: 42TM024-RC Audio and Signal Transformer. Click to expand... I wasn't trying to recreate the actual varitone. I was just wondering wether the effect of the OP's circuit could not also be reached by a circuit like the one I posted. I haven't tried it but it seems to me ...
