100 ohm missing

I'm doing my first project using a ggg big muff kit. I seem to be short one 100 ohm resistor.  I do have a 120 ohm resistor. Can I use it for 100 ohm or is it too far out of tolerance?

Thanks.

  er 10k should be eh ? whatever
 I'd stick the 120ohm in there..
 I'll go see what it probalby does:

  Must be the emitter resistors.
  I'd stick with 100ohm or more, <1k, larger values reduce gain.

It Depends.

If I'm building a high-accuracy circuit with 1% error, it might be 20% error or worse, flunk final calibration, and I don't get paid.

But in most fuzzes, it will give an insignificant difference. Less than 20% difference in knob-setting or finger-pluck for the same fuzziness.

You know that two 47 ohm in series is 94 ohms, which is surely within the slop-factor for any mono audio. (A "100 ohm 5%" resistor can be 95 or 105 ohms; most audio can be 10% or 20% off but they stopped making 20% parts a loooong time ago and 10% is out of style.)
