Tube Steak Fuzz

Having 4 unused CD4049 inverters in a TSF-type circuit just doesn't seem right to me.

So here's the Tube Steak Fuzz:

LEDlicious!  Sounds great too!

Looks and sounds interesting.

Have you tried a resistor in series with C3 between the gain stages? this will lower the gain in the 2nd gain stage

[Dave W]

nice as always charlie!  
now i have to build one. gonna put it before my bmp.
then i can tell people i'm pushing my tube steak into a big muff....  

[moosapotamus]

Thanks, guys!

I have not tried a resistor in series with C3. Not sure I want to reduce the gain. But maybe I need to hear how it sounds first.

Dave - LOL!!! Nice! I may have to put a BMP on my board, too!

Next up is the Tube Steak Supreme... Tube Steak + Mr.EQ + Clean Blend (just another way to use up all those inverters )

OR

You could try the gain setup like the Marshall effects use like the Bluebreaker
or the ASDF with a simple rewire

Connect the gain wiper to the output of the first stage (100 ohms, C2 node)
outside lug 1 to the 100K the other outside lug 3 to C3 (C3 no longer connected to the 100 ohms, C2 node)

This wiring should be an interesting gain control because both stages gain change with the control compared to the 2nd stage always being at max gain and the first stage gain changing

work out the gain with control rotation should be fun and

I wonder why people have not done this before with this fuzz?  It is an simple thing to do.

A standard 2-inverter overdrive can actually draw a fair amount of current (which is why the EHX Hot Tubes originally had an onboard power supply). 

What does the paralleling of all these invertors do to current draw?

[Gus]

Most likely two times more the current draw.  

I do not see a battery in the picture so maybe it was designed for a external +9VDC supply

Edit I read what I posted
To be more clear the current draw with two inverters plus (that current draw x two)

Maybe you could drive a little fan with those spare inverters, as seen lately with wampler's hairstortion
More gain, more blow...

But seriously, does it affect the tone besides more level?

Sounds great... can i make it with 40106?

I just don't bother with batteries anymore. My pedals are always connected together on a pedalboard. So I'm rarely concerned with current consumption. An external power supply is my standard protocol. Which also makes messing around with those extra LEDs no big deal from a current usage standpoint, too.

cront, the 40106 is a buffered schmitt inverter, so it won't "go linear" like the unbuffered parts. all 4069 and the "U/UBE" 4049. I think 74Cxx is unbuffered as well.
