The Tremolo - optical Tremolo kit

perfect kit and perfect sound.

Super kit !!!!!
il men a fallu deux pour comprendre quelques petites astuces , comme le sens de loctocoupleur par exemple !!
La première a un niveau de sortie beaucoup trop fort, presque en saturation , le trim ne suffisant pas à régler ce volume , je me pencherais sur la question plus tard .
En tous cas la deuxième fonctionne à merveille, cest un régal davoir autant de réglages sur un tremolo , je la recommande vivement !
Une fuzz factory a dejà rejoint le peadlboard, et je commanderai encore dautres kits , cest certain !!
Merci Musikding !

Another great circuit from Musikding. Nice standard trem sounds, but you can get some really trippy, almost uni-vibe-ish asymmetric wave forms out of this too. I love it. Not recommended for beginners though. Instructions and schematic are clear, but if youre new to this I wouldnt start with 5 potentiometers.

Great pedal with lot of options and sounds, no noise at all. Only improvement is to buy separate high precision 25k trimmer so you can set volume as desired, otherwise pedal is a bit louder than guitar signal and to match volume you’ll need something precise :)
Also keep in mind the polarity on AO1I element, white dot represents minus

What to say. It´s very good and versatile tremolo pedal. Love how it sounds. 5/5

Great kit! This was my first build and it was very easy. Didn’t work immediately because I didn’t solder one of my power wires correctly but it was easy to troubleshoot. Pay attention to the orientation of the optocoupler!

I just started building my own pedals (in my 50s) and Das Tremolo was my first kit. After some back and forth with R4 trimmer i managed to get gain on 1 after replacing original 25k with 2.5k. I am sure this could be accomplished with 25k with higher precision (as few noted), but 2.5k i had on the table :)
Rest of the build was straight forward, good documentation, helpful forum.
Wires on the pots are not for for fainthearted, but is it worth?
I am in 3rd hour of playing My Baby Shot Me Down with different settings and looking into led :)

Not difficult to build despite the five pots...Due to my limited knowledge of electronics I took my time to figure out the polarity of the optocoupler. It has so many great sounds that you wont really need another tremolo. Internally there is a trim pot that allows to regulate the volume and boosting the signal if you like... although at extreme levels is a bit too noisy.
