I just got 40 mpsa18 transistors in the mail a couple weeks ago so I've been designing fuzz circuits with them and really like how they sound. Q1 is a mpsa18, Q2 is a 2n3904, and Q3 is a 2n3906. I breaded it yesterday and it sounded great. I'm putting it in an enclosure today once I finish soldering everything to the pcb. I'll post a vid on my Facebook.
