INTRO:  After reading the fucked up shit on the original pearl box, I decided
        that there was an easier and cheaper way of doing the same thing with
        an IC and parts you probably have just laying around the house.

PARTS:  CD4049 RCA intigrated circuit
        .1 uF disk capacitor
        1 uF 16V electrolitic capacitor
        1K resistor
        10K resistor
        1meg pot
        1N914 diode
        some SPST momentary pushbutton switches
        9 Volt battery & clip
        and miscalanious shit you should have laying around the house.

                                       +  16V  1uF -

EXTRAS:
        To keep tones that you wanna use frequently like 1850 Hz then all you
        have to do is put in a variable resistor and adjust it to where you
        have the correct tone, then just put a push-putton switch on the line.
        You can link them together in a chain, etc.

There are many other good mods to make to the box so have phun and be smart.
