what fuzz could this be based on?

I just found a schematic showing 100nf output cap 47k to gnd series 2M2 500k volume pot.
The 100nf and 47k forming a 33hz high pass filter.
I guess the 2M2 restricts the signal somewhat. Told you it was loud.
I'll try some values tomorrow.
Thanks for the help.

I was wondering why the 2.2meg 500K was selected as a voltage divider instead of a lower set of resistor values with the same voltage divider ratio say 220k, 50k volume or even lower like 47K, 10k volume.
Was the 500K volume more available? 
Why would the designer not care about extra resistor noise?

Possibly. I have seen whole (tube) amps built with only 500K.

Who cares? Play loud!

i just ordered some of the 2n2222 as I dont have any 200hfe transistors
I'll be back
latest thing is i put the 47k to gnd from output cap
A 470k series and 100k output pot
still way too noisy im afraid to say. It might be a layout thing.Who knows,

Sounds better with 2n2222's abit less noise and I think once its boxed it will be good, maybe add a shielded input output wire
Thanks Gus
I thought I only bought 25, I must have pressed it twice I've got 50 now haha.
