Members amanonfire Posted October 4, 2005 Members Share Posted October 4, 2005 i am working on one of these for a friend. the wah works great but the fuzz is only half there. you cant hear it unless you hit the strings really hard. what should i be looking for to alleviate this? could it be the transistor? the ic was getting the correct voltage, maybe the switch?

Members Sir H C Posted October 4, 2005 Members Share Posted October 4, 2005 shorted cap would be my first guess. Link to comment Share on other sites More sharing options...

Members Sir H C Posted October 4, 2005 Members Share Posted October 4, 2005 Measure the voltages on the pins of the transistors. If the bases are not .7 V from the emitters, then there is your problem. Link to comment Share on other sites More sharing options...
Members analogmike Posted October 4, 2005 Members Share Posted October 4, 2005 HI, I may have it mixed up with the Vox fuzz wah but there may be a trim pot inside to adjust the fuzz volume. Good luck! Link to comment Share on other sites More sharing options...
