The Isosceles Pi

The Isosceles Pi is an exact copy of an original Triangle Big Muff PI that was made around 1970-71. It is a clone of a 1st version, second edition Triangle Big Muff known to be one of the best sounding Triangle Muffs. It is described on kitrae’s website as a “V1 Triangle Big Muff 66#11. I have posted two links so you can check it out. All though I have not owned this particular version, I used my experience with various other triangle & Ram’s Head versions such as transistor (Hfe) gain stages and applied it to this clone. This is a unique version of a Triangle Muff as related to component selection and values. It does sound spectacular for sure! See below for more info…..
