can this be used in any kind of pedal?

And I'll guesstimate 30 turns.

(160nH/T²) *30^2 = 144,000 nano-Henries, 144 micro-Henries. (Check my math.)

This smells small. Maybe try the top of the audio/guitar band?

144uH times 5,000Hz times 6.28 = 4.5 Ohms at the top of the guitar band.

The *only* place we want 4-ohm stuff in audio electronics is at the loudspeaker. This could be a treble-cut on a midrange. Except speaker circuits are HIGH current, ferrite may saturate easy.

Or wall-power entrance filtering to reduce digital hash, but the insulation is unsure, and hash-filters need other stuff and are best bought as a complete Approved unit.

You could split the cores, re-wind with much smaller wire. After many tries, you might have a Wah inductor.

1700 turns would be a start for a wah (I think).

This size of wire suggests a passive crossover for an 20 ~ 50 watt speaker. Or a wawa pedal for the giant at the upper end of Jack's gone wild beanstalk.
