Thanks for all the info guys, really appreciated...
Input and output are correct, though I wouldn't put it past someone with as little experience as I have!

Midwayfair, I'm going to bet the two points you brought up are part of my problem...

Boneheaded move, but when I opened my Oc44 from small bear it didn't even occur to me that the Resistor positions didn't necessarily apply to the madbean pedal schematic!
It should have clicked that going from 470k to 47k didn't make a lot of sense...

As for the transistor voltages, I hope I didn't damage it while troubleshooting, it's socketed so I'll pull it out to test it again while I try to determine my resistor positions.

Took the pcb and pot out, still only getting bypass signal, when I switch on effect everything cuts out...still hearing a little noise when I turn the pot, and placing the pot back in makes some popping noises, but still not getting any effect, just signal cuts out...

You mean just take it all out of the enclosure and test it?
If that's the case what did I do wrong?

Finally getting back into troubleshooting this first build of mine, range master...
Life got in the way of this project....

I'm getting a clean guitar signal with pedal off, NO signal whatsoever with effect engaged, just a very slight hiss that changes when I turn the pot.

Rechecked and reflowed all solder, components are All correct, EXCEPT:

I bought my OC44 from small bear, they supplied/recommended a 47k resistor for r3 instead of the 470k madbean schematic calls for.

When I test with my DMM I'm getting -8.7v on one side of the 47k, and only -2.9v on other side of resistor.

I'm also getting -2.9v at each pin of my OC44.

This is my first build, so I apologize in advance for the total confusion over here!

Hey!
I should have read the guide liens for tech help before starting, my apologies!
Transistors are from smallbear...

I'll read the guidelines and post back with all required info!

Hi Everybody

first time builder and poster, excited to learn...

i just built a MadBean Rangemaster as my first project...

first plugged it in using a Boss 9V wall supply, got horrible screeching as soon as i engaged the pedal.

after reading the forums I saw that it was most likely the a power issue.

I plugged it into a power brick and no screeching...Good news...

BUUUT...i now get a clear signal in bypass mode, but NOTHING as soon as i click on the pedal...

the BOOST pot does seem to affect the little bit of white noise in the amp, but NO guitar signal whatsoever...

really new to this, followed the MadBean wiring very closely, not sure where to start...

Thanks!
