I had “modded” my basic big muff. I changed all 4 transistors to the BC547B’s. Some ones in a black russian. Then changes D1,D2 to 1N914. But with D3, D4 i stacked the diodes to have 4 total. So basically im asking is this a common thing done and/or did i just make my muff a pedal that already exists.
