Astuce : Bad stone MK2 mods
here is an easy modification for your mk2. i did this with a vintage 500k pot only....didn't test other values...
can turn this phaser into your favorite phaser; really!
it mix the lfo and the manual pot diferently depending on the auto/manual existing switch.
manual pot can turn into a "center frequency" pot and you can have nice envelloppe folower phaser.
no noise and no volume change with this pot, just pleasure....
Peace & dub
