Just for curiosity, could you post the FET voltages? Thanks.

R9: 150K
C5: 220n with 4K7 in series
Some other value changes but none significant.

i thought this was a clone, and i was going to say "wow, this looks just like Bjorn's work without the goop." i guess i was right!

Nature potentiometer still 50K? Vf of LEDs? Thanks again.

They can probably built a mighty red distortion on the same board among other BJFe circuits with similar architecture.eda123 wrote:whats with all the spots for missing components?
Im LOLing at the construction. Here is a quote from Donner:
"Yes there is a whole team on this. If it was just me I wouldn't even be as fast as BJ so that wouldnt be much help .... St. Louis, among other things, is an old industrial town and I found some professional assemblers that used to do F16 and F18 avionics for McDonnell Douglass among other things and they can bring in more people if needed and they are top shelf and milspec...... my paint helper restores vintage automobiles and the lettering is done by a guy that also does lithographing and magazine layouts.
I will do some parts selection on some of the secret stuff BJ needed to share to get them 'right', and Ill be doing custom finishes later on and things like that, but for the most part I have professionals doing what they do best and I hope we can keep up with most of the demand and avoid long waits or lists ..."
Sounds like complete BS that those pedals are assembled by anyone with more than one BYOC kit under their belt.

Bravo Bootle. I got a decent coffee-out-of-nose reaction from that one.

C5:220n and 4K7 are connected together in parallel or am I wrong? Look at the source of jfet. I'm not sure about the elco next to R13 on the bearfoot board: 2.2uF or 22uf? I guess 22uF?WhiteKeyHole wrote:http://www.madbeanpedals.com/WhiteKeyHole wrote:Reference is "YellowShark_ver2.5" schematic.

Whether it is 22uF or 2.2uF the cutoff is below the lowest note of a guitar, making this one of the non-significant changes (if it's changed at all).
I did look, I traced the entire circuit without referencing the current schematic until I was done. You are wrong. The area is not clearly depicted in the photographs, but what we can see shows one end of the resistor connecting to the capacitor (the other end of which clearly connects to the source) while the other connects to a trace that diverges from the source of the JFET. Now, if we suppose that the divergent trace also connects to the source, the resistor and capacitor would be rendered useless and the control would work only to increase gain in the JFET stage. The resistor and capacitor could only be electronically significant if they were to connect to ground and we can clearly see that they do not (no connection to the ground, the top, plane).

Huh. Yeah, that would be R9. Good eye. Though it's 147k, as in the Bearfoot unit, not 14k7.

I think this is worth some further investigation. I would hate to think we had a mistake in our "official" schematic for the HoneyBee.
Also, there's a raging thread on the Bearfoot quality over at TGP:
