oh. i will try that too!

can i ask one more question. how did you manage your ground routings? did you do it the way the pictures show or did you do something special?

because my ticking noises are causes bei the ground wires off the circuit. thanx so far

Hope it helps.
I've used the shielded cable with no results... :slap:
My Supatrem has a fucking ticking noise... How could I solve?

You could try adding a power supply decoupling capacitor to the 9v rail, something like this diagram.

I've used a 1000uF electro, with no results :scratch:

Hi there gilmour_pugliese,
the diferences from my build is that i've used shilded cable on the conection of the rate pot to the pcb, and i think i've used also on the input and output jacks, i cant remember. The other stuf is pretty much the same, i think R1 on my build is 1.5k instead of 7.5k, R14=8.2k instead of 8.8k, C1 and C4 are non polar.
One thing you should do is not to cross the shielded cable that connects the rate pot to the pcb, with other wires, especeally dc wires.
It worked for me.

i got it to work now. i used shielded cables on the rate pot and switched to a mono pot. left the slow/fast switch. i thought i've done this some days ago without success but this time it's fine. maybe you need luck with this one :)

Just some shielded cable on the jacks, and BAM!
The pedal is super-silent :horsey:
Thanks to all for the tips!!!

Hi There

I've heard in a few songs (don't remember, could be radiohead?) a very nice tremolo effect on guitar that seems to ramp down its speed. Chord attack was really fast then in one second or so it would start ramping down utill it was really slow.

Anyone knows if there is a way of implementing this ramping effect in an optical circuit such as this one or the demeter/baja trembulator??

Any other tremolo does that already??

Thanks

Hey guys I tried to build one of these with the millennium C switching and I just can’t get it to work. Does anyone have a pcb layout and off board wiring layout so I can make a new board and try again using regular true bypass switching using 3PDTs?

Bump on this thread
got mine working

Question:
Can I use a DPDT toggle switch on Hard/Soft switch instead of a 3pdt?
Can I just solder the first 2 lugs?

Thanks
