Univibing a Small Stone

[mstoppini]

Hi,
I was trying to modify my russian EH SmallStone to produce a Univibe sound.
I've changed the caps to UV values, fixed the color switched to normal position and put a 500K pot to the output of the wet signal path using it as a Depth control.
It sounds not so bad but I'd like to know if anybody knows other mods to apply to it.
Particularly I'd like to get rid of a subtle, but nasty, 'tick tick' noise coming from the oscillator, when no note is played.
thank you,
Marcello
