Tremelo circuit

amelecsol2000 · 2nd July 2006, 11:09 AM

Does anyone know of a schematic for a tremelo circuit?
I have experimented with a 555 and a 741, " still experimenting "
anyway I have been looking for a schematic to get some ideas.
I found a good fuzz circuit but no tremelo.

Made some progress, got the tremelo effect I need , but the transistor is loading the output, switched it to the input and it also loads the amp.
Next step: I am going to try a voltage follower for the output of the tremelo circuit.
Still looking for a schematic , advise or ideas.

There's vibrato and tremolo, appears to be okay, but I didn't make it yet !

I'm very interested too, and I'll make my tremolo soon !

Nando.
Thank you , that link was just what I needed. Not breadboarded yet but the whole project is underway now.
A few days of routing the PCB on paper and I should be good to go.

Hi again !

FORGET that link, I've modified Rod Elliot's tremolo and is sounding just GREAT, for sure is the best tremolo that I ever seen !

I'll be posting the schematic soon, I've just finishied right NOW my tremolo circuit, it's on veroboard yet, and I made lots of tests, the tremolo is just... Musical !

Pictures !

Amelecsol, sorry, I'm so busy, my life is a mess since some weeks ago, I'll post it to you tomorrow !

amelecsol2000 · 24th July 2006, 01:03 AM

No problem , I know how things go.
I have been busy with a few other things myself. Back to the amp tommarow though.
