So to continue this thread, im sorry to say its been 2 days im trying to trace the circuit layout from scratch, and i am totaly unable to do it. I can't follow the traces, some are hidden under components, the switch pcb's traces are hidden too etc. All i can do sadly is take a picture and note all ...

wow excellent!!!! THANK YOU So for the values in the JF-09 i have (its an Harley Benton for info, not officially Joyo but its the same i guess) So : - the three blacks caps = The two of them "aligned" far from the "external" potentiometers are 4.7µF yes (C1 C4). The third one clo...

hi again, So i tried to understand how to make my own schematic from scratch of the pedal... and i can't ... i just understand nothing lol. I wish i could contribute tho but well. in the video i linked earlier, the guy is explaining the changes joyo made to the circuit from the demeter one. Maybe an...

Thanks for this thread.
I am having a FATAL ERROR while trying to access the JF-03 link.
A problem with the site i guess.
cheers

*Couldn't Edit my post* sorry I saw on another Topic here : https://www.freestompboxes.org/viewtopic.php?t=16105 That this Joyo JF-09 is a clone of the Diaz Tremodillo If you have any question, any request about pictures values etc etc that could help you in the process, don't hesitate to ask! I wil...

ughhh. Thank you for your answer... Since the current tremolo speed is only controlled by a Potentiometer, i really though it would be easier to achieve than that. I think its too bad, but i will have to stay with that regular tremolo that is going out of tempo while playing with my bands (nooooo it...

hey, I put my question here, cause of a CHEAP tremolo i bought (joyo JF-09 tremolo) This pedal have only two potentiometer as settings = an Intensity one, and a speed one. The speed one change the speed of the oscillation. Is it possible to change that speed potentiometer by a tap-tempo button? It w...

Hope this helps!

you are right!
I will try to post pictures of the pcb front and back tommorow incase it helps.
thanks again for your time

Thank you.
I am reading that for now. I understand nothing yet. They built a completly new board? i just would like to mod mine to be honest.
Still going through the topic tho. We never know ^^

Hello, I bought a cheap cheap Joyo Tremolo pedal. It sounds good but i would like to make it more versatile. For now on, sources are saying the Wave Form of the trem is Square Triangle. (something like this: http://s32.postimg.org/63jhwicnp/square_Trian.png ) So it let you ear a sweet tremolo. But i...
