EQD Hummingbird tremolo: rate LED?

[Plexi]

Hi forum!

Today I finished this great tremolo.


After searching, and analyzing the schematic... I didn't figure out how add a rate LED.
I tried to goes from B2 to LED +, then to ground, and LED don't blink.

Where I have to place the LED to have it?

Thanks!

Found it!!

Looking around for its base (Vox Repeat Percussion) , I found this:


Maybe it helps somebody: you need to add the LED in parallel with R11.... and voilà!

Any increase in the ticky-ness?

[Plexi]

Not at all.
But, I only have 5mm led: not too much brightness.

I added dpdt footswitch for another speed pot, and put 2 color led.

Thanks, going to try this soon

To my ears it changes the tone, ever so slightly - maybe I'm imagining but I 'think' it but makes it a little 'harder'. Doesn't effect the ticking, a separate direct ground for the rate cap (thanks RG) and tidy wiring helps to minimise that. I also use the Moosapotumus mod of a 20k trim for R4 - this helps dial in the variation in these transistors as some work better than others, and can be used to broadly set the speed range.

I'll try that mod, and see what happen with R4

thanks

I would like to add a "ramp" speed from one pot from another... is that possible in this desing?
