Klon clone volume pot having no effect

Postby BasherT » 22 Oct 2014, 19:33

I am making a Klon centaur clone brought from ETSY via a Chinese seller known as monkey king.

1.The volume pot is not working at all – it has no effect on the output level.

2. When the gain is at a low volume – there is a strange non-musical tone

3. Treble seems to work

4. The gain increase is very large

5. Output of battery is 9.15v

6. Voltage at the circuit board end of the red battery lead = 9v

7. Voltage at the circuit board end of the black battery lead = 0v
