The bold faced parts can be changed to generate a different tone. Since the use of polarized capacitors for C2 and C3 is kind of unskilled (it works most the times especially when using higher voltage capacitors ie. 63 volts) it is better to use non-polarized capacitors. 10µF non-polarized ones are expensive and or bigger. So much smaller capacitors can be used when increasing the value of the corresponding resistor at the same time.
