Not enough volume tonebender clone

[M420]

Im am new to electronics and building effects and i have just build a colorsound three nob tonebender clone. It sounds great only problem is that i have to crank the volume all the way and it still isnt as loud as the clean channel on my amp. I used germanuim transistors 3 ac 128 and followed the schematic at general gadgets website. The pots i used were 100k linear for the fuzz, 250k linear for tone, and 100k log for volume. Not sure if maybe the transistors are the problem or if I should replace the volume pot with a different value. If anyone can help me figure this out I would appreciate it greatly. Thank You

..You have to read teh debugging thread for us to be of any help.
  The pots being between 100k and 1m...generic answer is they're 'ok'..folowing the *schematic values with tested pots is 'good'.
  Posting the schematic and reference data on your build offers any, and lots of help.
  I suspect bias issues, understanding these is at the top of the list: debuggers first orders of business.
  In a gain stage:
  *Emitter real near or at *Gnd voltage, a small resistor between 'em.
  Base a diode drop above emitter [.6v or so...you said Ge, measure a ge diode...should be like that]. A volt or so, depending, should 'work' anyway.
  Collector needs to be between base and Vsupply for sure, often about 1/2 voltage, or 1/2v, or Vbias, or Vref [terms for 1/2 way between Gnd and Supply voltage.
  And state/show exact schematic, battery voltage measured.
  If you're building a PNP Pos Gnd circuit, the red battery clip wire is assigned to gnd. If it's an NPN Neg Gnd. the black wire [negative] is ground.
