Simple, versatile, responsive are the best words to describe this circuit designed by Brian Wampler. This circuit will deliver all the feel and touch you’d need to recreate Eric Johnson’s delightful tunes.
Wampler Euphoria (former name: ecstasy) ™ is Brian Wampler’s take on the Legendary and always desired Dumble Overdrive sound. As touch responsive as you expect but with a much wider tonal range than its competitors (like Zendrive or Dude™)
Gain and volume are very interactive; the bountiful EQ rounds the package off.
I highly recommend choosing 25voltage electrolytic capacitors to run the pedal with 18v for more clean headroom. Also very good as a beginner project because it does not require rare parts or and soldering.
- Smooth/Open/Crunch switch
