 More or less?

I can easily get the mpf's from ratshack but I have to order the 5457's. Building a Caitlinbread SFT pedal. :)

Not so interchangeable....

    2N5457    V pinch-off range -> -0.5 to -6.0, Idss range -> 1 to 3 mA.
    MPF102    V pinch-off range -> -0.5 to -8.0, Idss range -> 2 to 20 mA.
