I found a good schematic of EHX Bad Stone phaser and I believe it can be voltage controlled since it uses an op amp lfo to shift the phase. But I am at the very beginning of electronics knowledge and I can’t figure how to replace this LFO with cv control. Hope somebody could help me with that. I’ll attach the schematic. The lfo in schematic is lm324.
