Simulated inductor for guitar use
I'll take a stab at this. Most fuzzes rely on BJT's of some sort, which are current driven devices -- for "musical" reasons, guitarists tend to like the sound of fuzzes when driven by high impedance sources (such as guitar pickups); that is, not capable of providing much current. Driving them with a low impedance source provides far more current, changing the behavior of the BJT amplifiers, subjectively to the detriment of the sound. I imagine you're hoping to place your fuzz after a buffered effect, such as a tuner or a not "true bypass" effect, rather than at the front of your signal chain. That, or you have active (buffered) pickups.

In your linked page, the point of the RLC circuit is not to "unbuffer" the circuit per se, but rather to provide an impedance and frequency response that roughly approximates a generic guitar pickup when driven by a low impedance, high(er) bandwidth source. This can be useful when you have a nice bench signal generator, but that's not the case here.

You are interested in "debuffering", or raising the output impedance of the preceding stage. This does not in any way require an inductor or capacitor, "simulated" or otherwise. Just putting a resistance in series with the input should increase the impedance "seen" by the BJT. This could take the form of a single resistor enable by a switch, a bank of resistors with a rotary switch, or a variable resistor in the form of a potentiometer.
