thanks man,
I just build me an audio probe and tried to trace the fault.
Weird is that I can trace a signal to output and there is signal, its just really quiet, once I try it with bass there is still no sound.

I check the voltages tomorow, thanks again for your help

Hey man,
thanks for the reply, but I meant that the board isnt even working on my testing rig.
No sound at all

Got it to work, there was a scratch on the traces and i bridged tat part and now it works. great pedal

Hi there yall,
I just finished the Bloviator II.
I tried it out on my testing rig, now there is no signal going through somehow and so it doesn´t work.
Does somebody can give me the IC Pin voltages so I can compare?

There are no bridges between the solder lugs and metered all my compnents before putting em on the board.

Thanks in advance

Hi again,
i got to meter my ICs and transistors:

There is another forum entry with the correct voltages and some of mine dont aline with that. Because I am pretty noobish in electronics you might give me a hint what is wrong with my board.

These are the voltages:

I hope someone can help.

Thanks in advance

Hi People,
short question.
I wanted to include a 8mm green LED in one of my builds.

I put it in with a 2,2k ohm resistor but there is just a really weak light. Same with a 1k resistor.
Is that normal and should I try a even smaller value resistor or did I screwed up with the off board wiring?

cheers

Hi Brian,
thanks for the tip.
I just took the PCB out and tried it again with the prototyping board.
Now the PCB has the same problem when its out of the box than before when it was boxed up so my wiring should be all right I guess.

My meter is broken so I guess I just switch the ICs and look what happens.
Just have to wait till they arrive.

cheers

Hi members.

I just finished the lowrider pedal and tested it via a prototyping rig ala Brian (great tool by the way).
It worked like a charm and is a great effect.
I made it for my guitarist and after he checked it it and and liked it I wanted to put it in a box.

So far so good.
Now  my problem is that after I put it in a box I tested it again and something strange occurred.
When the clean knob is all the way up there is no Octave at all (neither octave up nor 1 + 2 down), but with the octave up on full there is fuzz but no octave.

So when I turn the clean knob all the way down there is fuzz to but no really prominent octave with the octave up set to 10.

The same with the two octaves down. when I dial em in it is more like I dial in more bass frequencies rather than octaves.

I hope this makes sense in some way.

Thanks in advance
