Bazz Fuss impedance and inductor issues
« on: February 12, 2018, 10:34:12 PM »
Hello all!

I have just started my DIY pedal journey and been playing around with some different Bazz Fuss type circuits. I have access to a lot of old electronics at my work and have build this pedal out of completely recycled components (except the vero and case), I ended up settled on a nice sound using two BC337 transistors in a darlington configuration.

A friend suggested I design it so the effect has a wet/dry blend with the clean guitar signal so I preceded the Bazz Fuss circuit with a Split 'n' Blend found here:https://tagboardeffects.blogspot.com.au/2012/02/split-n-blend.html it mentions there that it will not work properly with inverted signals so I added another recycled transistor (2n4400) in order to un-invert the signal at the end of the Bazz Fuss circuit which worked great.
'
My only issue now is that it sounds like I have lost some of the balls of the original Fuzz, I don't believe it is the 2n4400 as I used an audio probe and it sounds the same before and after it. From my research the Bazz Fuss likes to have a high impedance input and the original home-wrecker page suggests using one side of a small audio transformer on the Bazz Fuss input. One side of the 42TM018 transformer has an impedance of 10k and according to here http://www.....org/viewtopic.php?p=148640#p148640 the primary winding of the 42TM019 (also 10k) has an inductance of above 2H.

I have access to lots of small (680mH) inductors that I can recycle, my question is could I achieve the same effect of the audio transformer by having fourh of these smaller inductors in series on the input?
