BTW if you add a 2k resistor in // with the resonance pot you must leave
unchanged the values of the serial resistor (1k) and Q3's emitter 
resistor (2k2) !

> Another solution is to use your 100k pot with a 2k resistor in parallel
> this way the total resistance is 1k96 (that is the maximum gain won't 
> exceed 4).
