so, a 2n2 cap (approximating the 2.4 cited in the article) between central lug of the vol pot and ground and, voilà , the hendrix coil cable trick is served, right ?
Yes... it emulates the parasitic capacitance of 15 to 20m of straight typical guitar cable (necessarily shorter when the cable is coiled).
Now, 2.2nF is already a bit high. Not unusable but quite noticeable. The 1nF value mentioned by hamerfan and that I also use is the threshold after which stray capacitance starts to be sonically obvious with a Strat. It is therefore a good starting point IMHO...
I leave aside the question to know if a mere capacitor can mimic ALL the "parasitic properties" of guitar cables. The PRS "Sweet switch", for instance, is based on a delay line - IOW a series of inductors separated by capacitors to ground, meant to give a better approximation. But a cap still does the job IME. YMMV.
