Muff Fuzz volume increase?

[Focalized]

Put together a basic transistor Muff Fuzz. Sounds pretty good in between a Fuzz Face and a Big Muff. A bit dark with the guitar volume up.

I just wanted to know if I could increase the volume a bit. Similar to the way you can with a Fuzz Face. It's basically unity I think. Some boost might add to it I think. The diodes bring the volume down I suppose. Was wondering about any of the resistors.

try using a smaller input cap, that will give slightly less fuzz, but will boost the volume a little in the more useable range of the pedal.

too muddy? turn your guitar knob down a smidge. or add a small resistor...maybe 330r-1k to ground from the input of the board.

can ya post the schematic? easier to speculate if looking at it.

another thing if ya want more fuzz and volume, directly gound the emitter(s) or use a small cap...10r-1k to help stabilize it. you can bypass it with anywhere from 220n to 100u electros for more bite in the high end for feedback. 22-47u is often good, too high can cause motorboating.

This one?

I built one quite a while back, but don't remember it being particularly quiet. You're right that the diodes will drop the output level somewhat, and Ge diodes will make the signal loss seem even more apparent than silicon. You could try a 5k or 10k pot wired as a variable resistor in series with the diode pair to ground, which will reduce the amount of clipping and increase the output as you dial in more resistance.

or ditch the 100k between the two emitters and directly ground the second one.. that's the basis of my lardacious phat bastard

If built correctly, I'm betting it's the diodes...As nocentelli noted...did you use si or ge diodes?  either way, try 4 diodes (2 in series each way)

My schematic dissapeared but yeah the one posted. Ill try what you guys said if I make another. Diode lift, input cap and all. Just curious. It's so much like a fuzz face so I suppose anything ive improved on that will work on this.

Used silicone diodes. It is ok as is just wondered how much headroom the was with just resistor changes.

YUP.  Try this - if the circuit has enough gain, it will have to put out a 'louder' (hotter) signal before it gets clipped off by the diodes.   Once you clip, that's all she wrote...

If you remove the clipping diodes the Fuzz should get very loud.    As others posted try different diodes.

What are the transistor voltages?  This is a good check to do with a build.

If you remove the clipping diodes you might want to use two resistors in 2nd transistor collector leg like in a FF circuit you could try 8.2K and 1.8K this adds up to 10K

A link to a thread. I simmed a muff fuzz like circuit note the transistor voltages they did not change much with different transistors.   I have not built this circuit.
