Russian muff with bc239b. It doesn't feel "right"

[pietro_moog]

Hi guys.
So, i built a ram's head last year, but it never sounded good to me.
A few weeks ago i've subbed the transistors with 2n2222, and that thing is Heaven now.

Then i've built a russian green muff with bc239b, and it sounds like good, but it doesn't feel "right".
These transistors have HFE between 250-280.

What is the "right" HFE for a russian big muff?

It usually never mattered as unlike a fuzz face the muff has always been quite forgiving as to what transistors you put into them. That has usually been the strength of the design as EHX has literally shoved any tranny that was available at the time into them. All the sonic changes that come with the various models usually come from differing resistor and cap values. That being said, if memory serves me right there is a difference between BC239B's or BC239C's, and the latter seems to be the one that gets used in muffs.
