Hi everyone
Hope you're not melting at the moment (the UK is having another dreadful heatwave and I'm hiding indoors so thought why not entertain/annoy the good folks of I Love Fuzz with a demo of a fuzz/ring modulator pedal thatI've built?

This a demo of a Jen HF Modulator effect (the original circuit is from the mid 1970s) and is an audio rate tremolo with some fuzz in it - it creates some delicately odd fuzz sounds; I would describe it as being an entry level ring modulator for people that don't like ring modulators! I modified it to have a clean boost and a fuzz option. If you want to build your own then please see the vero layout that I've drawn:
