PART TWO OF EASY PEASY LEMON SQUEEZY
Make your lemons into a synth with this circuit :- https://www.youtube.com/watch?v=WyAIW–5fIA
heres the schematic for the active filter, made by rene schmitz based off an MS20 filter, this forum is useful for it :-
Super simple build!
1 10k pot and 1 100nf ceramic capacitor and 2 jack sockets
mess around with values! and types of capacitors. the larger the capacitance and larger resistance, more frequencies filtered!
even try electrolytic capacitors! all the way up to 470uf! give it a go.
