Fuzz factory too quiet?
A have recently built a fuzz factory clone from the vero layout featured here: http://goo.gl/EYNqZ
all seems to be working (oscillations etc as well as some great useable tones) However the pedal is extremely quiet, needing almost full volume on my Marshall 30W amp to gain any useable volume. From what i know about Fuzz factory's this is very unusual? currently the volume pot is disconnected as when i connect it to the board, all oscillation is killed and all knobs lose functionality? could the quietness be caused by dodgy soldering or dodgy transistors?
any ideas/help would be greatly appreciated.
I am using AC128 germanium transistors if this helps?

yes and yes. tell us more about your transistors, have you measured them? What are you using for Q1?Joshtate wrote:could the quietness be caused by dodgy soldering or dodgy transistors?
also a high res picture of you board (front and back) would be helpful. most problems with vero originate in dodgy soldering or components that are placed on the wrong track/hole.
Also, have you verified all cap and resistor values? (e.g. 470k instead of 470R is a very common mistake)
For Q1 i am using a 2N3904 as stated on the layout, currently i haven't measured the transistor values as i was unsure of how to do this, i think i understand now and will get back as soon as i have. all of my component values are verified, (i checked several times!). Also should the stab post affect the volume of the output? as when i adjust the stab the volume also seems to decrease.
