All new ones from now on will feature this tweak, and I can retrofit yours if you want a more gentle feel to your warble.

Marc,
Is it still able to get the original sweep ---- that is really what sets this type of modulation apart is how it fits with your rig and since there is such a wide difference in speaker range , what could sound wrong on Jensens could be just right for Celestions etc...... might be good to have some LFO sweep 'gears' ~ but thats another toggle.....

Thanks Marc!

Change C12 from .12uf to .01uf (filters the LFO a bit less roundly)
Also change R29 from 820R to 2.7k (keeps the LEDs from over-saturating)
I suppose I should just start making them like this from now on. A bit less "Uni-Vibe"ish but I think much more useful.
