This has gotten me out of additional fees from dhl.

I juste ordered some stuff from musikding last week. Didn't weigh a lot but more than some pcbs and was a somewhat big envelope. Shipping to France was 2,10€. Maybe they have a special deal with Deutsche post or they are eating the extra cost.

Never built it. But there is this.

You should definately get a breadboard for this. It is so easy to put together. Try playing around with the input cap. Lowering the value changes the sound a lot. Lower values will give you a more overdrive/distortion kinda tone. Higher ones a wooly fuzz tone. Can put a switch between the 2 or even a pot.

Also if you don't have one already. Get one of the cheap Chinese transistor testers if your multimeter can't do it. That way you can figure out what you like or don't like with the actually values of the transistors more than whatever part number is written on it. Transistors with the same part number can have really different values.

Vero layout of this thing? You are nuts

I'll try to prop it up tonight.

I don't have a tripod

I can try to take other photos if you want but it'll probably be the same since my only camera is a smartphone.

I tried to see if I could scan the boards. It worked ok but I can't get the board flat with the headers in place

Pics sent. Let me know if you need any help tracing it or verifying values for you

Maybe we should start a thread at diystompboxes on this? Get more people involved in it

Never looked for faders before.  Easy to find replacements?
Not always but sometimes you can find something close enough, firstly what brand are they? Then you'll want to measure the dimensions and take note of how the pins are grouped.

The faders say AB made in the uk.  Allen Bradley?

The good news is the headers arent actually soldered.  They are these scissor things that clip the boards together and thé board came apart easily

That's great news, can you get images of both sides of each board??

I think finding replacement sliders is gonna be tricky, is there any indication of what alues they are??

I already took the pics. Send me your email by PM and I'll send them to you

Yes the values are written on the PCB next to the faders.

Some more pics.  Other side of the pcb and the preamp.  Never looked for faders before.  Easy to find replacements?

Some of the headers on the bottom right side are green.  I'm not even sue there is a pad there anymore

As a test yesterday I traced the preamp in the foot pedal. It matches up with the available schematic. Which is readable. Nothing sexy or exciting about the preamp but it's a start.

The fuzz is pretty cool. If you put the rise time to slow the fuzz fades in. Don't think I've seen that in a fuzz before

That led won't light up if the L pad at the bottom isn't touching ground.

Other than that it's hard to tell without voltages. And without the input and output wires in the picture. Did you have a ground wire going to the input output Jack's?

Scruffie how would you advise cleaning them? And they are sockets as in if I pull on the ic it will come out?

This thing has definately been worked on before there are some standoffs missing. There are definately some bad contacts also. If I touch the board right I get phasing. Seems like all the wave forms work as well as the different phase modes. Can't say I've heard anything that sounds like meow yet though.  The growl switch seems completely worthless. Just makes it sound like water bubbling  maybe I'm missing something

I can give it a go at tracing but having never traced a pedal before to tracing this beast is quite the jump.


Unless anyone else in Europe is up to the task I can ask my friend if it's ok with him to loan it out.  He'd probably say yes if that person was willing to repair it too.

As for scanning the pcbs I'll see what I can do. Any idea to separate the boards with soldered headers?
