Bring it on! I say,
I just finished the Patchell Vocal Filter this morning at around
2:30am. With 159 100k resistors, 106 .1uf caps, a mess of
other parts, and not to mention 57 pots (half of which I wired
backwards and need to fix). After that one I am feeling like I can
take on just about any Mega Kit! OK, I will get off my high horse.
I would be happy to make a deposit via PayPal...
