Impedance-lowering inductor

[roadtonever]

Could anyone point me to an inductor suitable to place where a tone cap would be in a passive guitar circuit?

RTN-

We've had some discussions of this previously:

guitarnuts2.proboards.com/index.cgi?action=display&board=wiring&thread=3605&page=1

In that thread, the use of small audio signal transformers for this purpose is discussed- wiring only one-half of the transformer gets you an inductor. There is some calculation of values therein as well.

Not sure what you want to achieve here, but my limited understanding of this concept is that the inductor does not replace the cap in the tone circuit, it is used in conjunction with a cap to give a "notch" response. The inductor's value will depend on the value of the other components (pot and cap).

Thanks Newey! I've used a Bill Lawrence inductor without a cap so far in my bass. As you dial down you get less mids without really cutting them until near the low end of the knob it sounds thin like the way a solidbody sounds acoustically.

The Impedance of an inductor is a direct corelation to frequancy, a Higher value inductor will cut more bass ( Unlike a capacitor where it would cut more treble)

That's interesting Yew. Do you think it's worth seekeing out a lower value than the common 1-1,5H? I'm digging the Qtuner-like fidelity I get as I turn down the control but I wish I could go "further" before losing lows.

I have no idea, thats just something i learnt in the electronics module of my engineering degree.. I dont know how to apply it to a guitar, but i imagine you could use one as a bass rolloff
