Low Pass Filter with LFO schematic

[stringsthings]

new build from the Pedal Factory  

the circuit is a slight mod from R. Penfold's original design ...



the LFO section can be modded to suit your tastes ... for this build, i used a non-polarized capacitor for C6 ...

Happy Modulation Day !

here's a soundclip of the circuit ....

signal chain:
guitar --> Distortion --> Penfold Low Pass Filter --> software amp sim with chorus + delay

( if anyone's interested, i can post a veroboard layout )

That could produce some serious dub stylee guitar sounds... nice!
