The various Muffs sound great man, including the triangle. I've now done the triangle, 73 rams head, and the green Russian variants on the mudbunny boards. I think my favorite is the Russian, but then again all the muffs sound different with different gear (guitars/amps ect.) But I will say the rams head sounds amazing as well. I used 2n5089's (around 520 HFE) in the Russian, and 2n5088's (around 320 HFE) in the rams head and triangle.
I’m not sure why you would omit C2, in the mudbunny schematic, it goes straight to the base on q1 then to the sustain pot. All other schematics of the triangle spec miff have this cap in place. I might stick a 560p cap in there to see what happens.
