Has anyone out there tried building this yet?  I am really excited and about to rush out and grab the parts but just thought I had better  check that the circuit havs been validated.

Just tried building it from my spare parts bin.  Most parts are the right value, but I sub'd a few, nothing much, just devil water for the holy water.

It doesn't sound quite right though, there's an awful hum in the background, apart from that, it's all good!

I love this!  Cracked me up.  Got me wondering where the "talent switch" was supposed to be?
