how to implemen a lfo led into Bloodstone Phase Shifter (EHX Bad Stone™ Phaser )

[njkmonty]

has anyone done a led lfo rate mod to this circuit?

Try a diffused LED from pin 8 of the 324 with a 4k7 to ground, if that works but doesn't turn 'off' enough, add another 4k7 in parallel with the LED.

If it works but messes up the sweep you'll need a transistor buffer.

cheers , i was playing around with the 324 legs but couldnt get any throbbing,  i will give you suggestion a go!

thanks

no good, i couldnt even get any voltage variation at all from pin 8,  bummer, none of the other pins or rate pot legs etc had any voltage lfo changes i could find

[Scruffie]

No moving voltages at all? This might seem like a silly question but, you weren't in manual mode by mistake were you?

[njkmonty]

i thought that too,  but will double check again!

got it working!   yes you were right  i didnt work on either setting, i was using the wrong resistance range,  it turned out  that 82 ohm resistor gave me they best throb. 

thanjkyou!!

i just connected the resistor to the leg of the transistor which connects to the pin of 324 you suggested,, thanks again!!!
