The LEGOmonster is the very first thing I circuit bent, years ago.
I used a set of computer speakers for the main unit, with a single-button toy patched in.
Be sure to check out the "sick beat" at the end. I am planning on updating the LEGOMonster with what I've learned since I made it, so I thought it would be good to archive how it initially worked.
I have three noies tapes for sale. All of them are from Seattle label FEAST Recordings and $3 each (and, as with all FEAST releases, each tape comes with a secret trading card).

Contact sales(at)glitchbent(dot)com if interested. PS: Sorry about the lack of electronics updates! My soldering iron keeps randomly cooling down one moment, and then working again the next. It is quite frustrating. Any tips?
I finally found some time to finish modding my Dunlop Cry Baby.
There are 4 pots and 1 switch added. I added a 1k Gain/Bass pot (+32ohm resistor), a 5k Mid pot, a 50k Input-Volume pot, a 100k "Vocal" pot, and I replaced the sweep cap with a switch between 0.012uF (treble) and 0.1uF (bass). UPDATE: 0.012uF was too high (in frequency) and 0.022uF was too low, so I'm going to try a 0.018uF as the treble cap. Also I made the pedal true bypass and cut the rubber stoppers a little so that the pedal has more physical range.
These two pages pretty much tell you all you will need to know to mod your Cry Baby:
