Hi, I am trying to get a Big Muff into the chain. I have tried a Little and Ram's Head and although they are all right on Clean and Crunch and do not completely mess up OD2, they never get along with OD1 it seems. The sound is like something broken more than something playable or musical. As if the Fuzz tones sometimes happen and sometimes not. It is most prominent among bass tones in chords. A very broken sound, but broken as in "not even cool broken". Like a comb with many teeth (?) missing. I have tried to bias it, but went for 35/35mA without checking the plate voltage.
