Just looking for a simple LFO to add to my rebote. i've looked at the one in the gallery and the trem lune lfo add on. just wondering if any had success with a good sounding and controlable LFO. thanks

Have a look through the Clarinot thread for the LFO mod.

Change the Rebote's delay pot to 100k, add a depth pot and LDR as in the Clarinot Cubed.

That's one way to do it anyway

where does the ldr/led go on the lfo mod? it looks very simple. thanks

The LED is marked up in the LFO schematic: http://i210.photobucket.com/albums/bb292/frequencycentral/ClariLFO.jpg

For the LDR you'll need to duplicate the arrangement from the original Clari(not) schematic: http://i10.photobucket.com/albums/a113/midfielectronics/mid-fi_clarinot.png ie, change your Rebote's delay pot into a 100k, add the depth pot, LDR and 1k resistor. You probably won't need the 1k resistor as teh Rebote has one right next to pin 6.

awesome! 2 questions:
Why is the 100k pot necessary?
What LDR/LED combo did you use?

Thanks

Resistors in parallel. The 100k depth pot will lower the value of the delay pot, so using a 100k gets it back up there.

What LDR/LED combo did you use?

LDR: Typical dark resistance = 1M Typical light resistance = 2K - 4K

LED: Super bright white 5mm, but others will work well by varying the 100k resistor marked with a red star in the LFO schematic.
