OIM Stone Face

OIM

Stone Face is a Fuzz pedal built around two PNP germanium transistors. It can be pretty aggressive for a Germanium device but cleans up when you turn down the guitar volume.

To make it more flexible I have added the following features :

• With the Stone Face tone control, that I now have renamed to bias, you can tweak the clipping to be more or less aggressive .
• I have also added a three way switch with the following function:
  1. No limitations
  2. Smooth
  3. Less bass

Function:

• The pedal has true bypass when turned off.
• Red LED indicates when the effect is on. (When LED starts to fade you have to change battery, the effect will still work though.)
• You can use either a 9 volt battery or 9VDC power adapter (standard negative tip).
• The design has a safety resistor so you can not damage the circuit if you accidentally try to use an adapter with the wrong polarity.

Stone Face is germanium fuzz with following features:

• Fuzz: amount of distortion/fuzz
• Tone(Bias): character on the fuzz
• Vol: adjust the volume
• Switch: three different colors of the fuzz

Suggested settings:

• Turn the Fuzz effect fully clockwise
• Use the tone(bias)control and the switch to adjust the character of the Fuzz effect
• Use the volume control to adjust the out put level
• Use the volume control on your guitar to control the amount of gain in your sound. You can go from clean to scream only using this technique.
