Can you still edit the text after converting to paths? Should not be able to. Re colours, are you sure you are changing the fill colour and not the strike? You only need the 2 swatch colours

I think you are right. It looks like an orange squeezer with a lot of the mods Mark Hammer has suggested along the way. Plus a blend and tone control. Bears no resemblance to the 1776 from what I can see, except the input stage.

Try flipping the transistors the other way. I have never seen a 5088 with that pinout (you might have it right, I just have not seen one). Usually the emitter is the leftmost pin when the flat side is facing you.

What transistors are you using by the way? They might have the wrong pinout which could be your problem

Each stage is different. The input booster stage just makes the signal really loud. If yours is quiet then your problem is here. Clipping stages will distort. It sounds like your pot is wired backwards, that's not really a problem. Sounds like you have a cheap breadboward if the sound cuts...

When you breadboard it, you should build it in stages. Build the input booster stage, then check it works. Then move onto half of the clipping amplifier, check it works, then move to the next.

Ok so if anyone is interested at all I finally figured out what was REALLY going on. My lt1054 was faulty so Q2 was not getting the correct voltage. My trick above helped to pass signal but not to get it to sound good. What a nightmare! At least it sounds good now.

Have you tried re soldering the joints? I know you said they look fine but you really should solder all parts. Especially the parts buddylereow pointed out. I have had a badly soldered capacitor stop a pedal from working eve. Though it looked fine

How did you go with this? Did it work out? Im working on a similar project at the moment.

The 2SK30A-GR seem to have the pinout Source, Drain, Gate, versus the J201, 2n5457 pinout which is Drain, Source, Gate. Are the source and drain interchangeable here or will I need to use a differnet so-23 to to-92 adaptor for this?

With a multimeter, select the mode to measure voltage. Clip the black lead onto ground and touch the red lead onto the pins of the op amp.

Sorry, what do you mean you don't get signal from the drive pot? Have you plugged it in and it works now? Do you mean that the drive pot does not change the way it sounds? Not being rude, just trying to work out what is going on.

Is this true even when you press the switch? You should get audio on one side of r1 but probably not on the other side

Here are some voltages from a clone that I made. Based off the same schematic but I made my own pcb. Just the lfo and the clock bit based on your description I think your problem is here. Maybe you could post you voltages here for all ic and transistors and we can check for you?

Awesome, that all looks good then. Nothing stands out to me as being obviously wrong. I looked at your resistors and they look like the right values. Have you tried resoldering everything? I had an electro cap recently that looked soldered in but actually had one leg floating which caused the...
