the base is headed left on the image i triple checked my traces  i hear hiss and goes with the fuzz knob but no sound im questioning the way i hooked up power sice i didnt do battery thing . using danelectro power supply pretty sure i got polarity right PLEASE HELP AAAAAAAAAAAAAA ??? >:(

it's a germanium one right? If yes, the polarity seems ok.
you should check again calmly the soldering points, 90% of the time I have a hiss or no sound, the problem comes from there (even when double checked...you can always miss something!)...there could be some kind of shorting...
maybe if you could post a larger recto/verso image of the circuit...
I was born the year Elvis passed away...it probably means something!

  It doesn't work?.. for that:
  the debugging page sticky is 'it'...we can debug it !
  If the LED anode is 'pointing toward' gnd. [with current limiting resistor thrown on either side of LED/Resistor circuit] and it lights, you have a positive Gnd. circuit.
  I couln't find the schematic from the link, PNP Pos. Gnd. ?
  Tha'd be good.
  We'll be able to tell more after some debugging, it's hard to see electron movements, but they can be measured in various crude but effective ways.

IM MOST CONFUSED BY TRYING TO WIRE IT UP TO A PLUG IN AND NOT A BATTERY AND WHERE THE TRUE INPUT OF THE CIRCUIT IS .

  Too much heat and too much solder.
  Adding solder adds cold.
  Refresh the tip [clean/retin light], tin the part, try to get the heat to flow to the 'other side' through the solder, adding little bits until all the surfaces 'grab' the solder.
  about 1/3 that amount is sufficient to provide physical strength.
  Electrician solder, 60/40.
