I recall having had problems with the TC1044S charge pump (similar to the TC1660S), some of which staying in the low frequency mode 10 kHz instead of 45 kHz that it should operate at when pin 1 is connected to the + voltage. I had exchanged with Klaus of Musikding about that… and we had concluded the the TC1660S was the…Read more

How comes that your ICs are non marked ? How can you tell the TL 061 from the TL 071 ? MUSIKDING usually ships ICs marked.

After you flipped them ICs “the other way around”, maybe they are burned…

What do you mean by “changed the transistors” ? did you have another set of matched ones ? What exact model…Read more

That is the case with 2N5457 vs the 2N5952 documented. Also they need to be matched.

Simplest way to do it is to have a short piece of bare wire wrapped around one jack’s thread so once the nut is tightened this wire is in contact with the enclosure (trapped between jack’s body & enclosure). Then solder this wire to the ground of the jack. Done !

It makes sense to have three LEDS if you want to have information on the complete status of your pedal : main ON/OFF, SPEED (normal/double), KILL (full effect or buffer only). I mean, one LED per foot switch. Of course if you have one or two toggle switches instead of a foot switch, you can look at their position to deduct the…Read more

  • yes of course the main 3PDT switch is mandatory (at least if you wish to shut down the effect), and not shown on the image which just shows optional add-ons.
  • I would not build it like it is on the youtube vid. I would use the housing the other way (horizontal) and make sure there is enough spacing between your…

  1. I am surprised : most footswitches are latching indeed, and I had difficulties to find a non-latching one that I intend to use for the speed boost option.  I like the feature of the LED blinking to show the rate of the LFO even when the effect is not engaged (but I know that some people are not comfortable to have a LED “on”… when the…

And white wire from main PCB, output side, should go to the ground (sleeve).

Also you should have a look at the “LED rate mod” in the forum.

I have put a MOWAH board in an old CRYBABY pedal with almost all possible mods, pots, toggle switches, and I had the dreadful “heel click” syndrome.

I have tried everything around the potentiometer to change its taper, its value (with paralleled resistors), tried an old pot, to little or no avail. I suddenly realized that moving…Read more

Just to inform that I finally got a stereo jack socket, installed it and it works beautifully to vary the speed from an expression pedal. Therefore I did not have to butcher my beautiful Cry Baby.

I am new to this forum, hope I can attach files. First a view of my build :

(Wow, what a big picture ! Wish I knew how to downsize it…)

I had a hard time figuring out why this Dr Phybes dod not work at first time. After hours of debugging, I realized that the kit purchased from MUSIKDING was loaded with FETs of a different reference … and these are “pinouted” backwards !!!

Therefore, I did the bicolor / rate LED mod… and it works perfectly !

The return path of the bicolor LED cathodes I connected to the footswitch normally, but the middle contact of the footswitch goes to lug #3 of the pot (instead of 0V).  As the footswitch selects either red or green cathode, the LED now…Read more

First, on the schematics P1 is used as a variable resistor, with lug 1 unconnected. This is confirmed on the PCB, pad for the lug#1 goes… nowhere. Then, why bother to install the red (pink ?) wire on the WIRING picture ? We can save a wire & two solder…Read more
