MSA PEDAL STEEL: Jordan Bosstone Fuzz - Nashville Variant

Just a little one from the Bosstone family.  This is said to have been used in MSA Pedal Steel guitars, and it's basically a slight variation on the Nashville Bosstone circuit.

These can be a bit noisey, so really have to watch your wiring and try for quite low gain on Q1.  

It can be a tad thin at times, although this mainly shows up on lower fuzz settings - increasing all of the 22n caps helps, some recommend 47n.  There's almost no point increasing the output, if you leave the input cap as is.  The cap coming off the 560k pair of resistors is also worth playing with to increase bass response.  This is really obvious when you dial the fuzz right back.  

This is an impractically large layout for some, but it will work for what I have planned.

The version I made below has a larger input and output cap - sounds great, especially on low fuzz settings.   Strangely for a circuit capable of all-out fuzz, I think my favourite setting is for an almost clean sound that gets a fuzzy when I dig in on my guitar.

2N2102 for Q1 ~50hfe, 2N4036 for Q2 ~110hfe.  180n in, 22n, 47n out.
