Title: new UGLY face clips
Post by: igor12 on March 08, 2009, 08:33:42 PM
Some new ugly face clips.  I didn't use a JRC386.  I used an opamp as a comparator to create square wave. I tried it with a couple of different op amps. TL072, MCP602, 1458.  Take a listen.

  Nice quack and also 'limited' sounding background noise.
  112 alien hits.

A+ 

Not really my kind of thing, but I would consider building that just for kicks.  Kinda like a Scrambler.  It yours much different from a standard Ugly Face?

The TLO72 sounds quite evil.

I'm curious what you have for this schematically.
Please let us know.
thanks

I'll post a schem when I get home from work.  If you google "opamp as comparator" or something, I am sure you'll see examples.  I just replaced the LM386 with a copmarator.  No other changes were made.  I think the tl072 seems cooler because I did a dive bomb at the end of the clip.  I have come to the conclusion that the orginal LM386 sounds the best.

If i woke up in the night, and heard these sounds coming out of nowhere, i would certainly draw the conclusion that an alien invasion was on the move, then go back to sleep.

Seriously though, this thing sounds wicked. I've always looked at it as a Fuzz Face deriviate, but it doesn't sound like one!  ;D
