This just came in the mail :). All I can say is, what a great sound! These really are the real deal in phaser pedals. It will be awesome when the Polytrog project is complete, this is definitely worth building! The tracking on the envelope setting is outstanding, very musical, and I usually don't like envelope filters that much.

I just got one too, they really are great! Yours is in a bit better nick than mine by the look of it.
Wow, great score. Congrats. I'm looking forward to building one when Brian gets it out.
