Mudbunny rig test

[teknoman2]

I just finished Mudbunny, green russian version and I test it with my rig test

but there is something strange happening.

The clean signal of the input (guitar) comes to the output without any distortion,

I dont know what to do.

Thanx a lot.

Well, the first thing you should do is check out our rules and tips thread here: http://www.madbeanpedals.com/forum/index.php?topic=902.0

After you've read that and tried some things, come back and tell us how it's going.

I just found the solution,

my rig tester had the problem.

Despite that, I have a question, I use 2n5088 transistors and I am not sure about the orientation

of the transistors, should I put them like madbean's or backwards?

[jtn191]

they should work in madbean's orientation, as will any other EBC transistor

[teknoman2]

Ok thanx for the quick reply,

I am posting my voltages of the transistors

Q1=0.06/0.61/7.17
Q2=0.04/0.58/7.35
Q3=0.04/0.59/6.97
Q4=0.31/0.86/7.50

Are they correct?

[teknoman2]

Does anyone know if my transistor voltages are correct?

Someone told me that it must be around 5 volts on the collector.

Also I would like to make mudbunny with more gain and bass,

any recommendations?

[teknoman2]

I found my issue FINALLY,

I had replace my transistors backwards, I didn't see that madbean's had put BC 549C on the layout

so I had put my 2n5088 like BC 549C.

Finally I reversed them so my voltages are 4.5-4.6V on the collector.

Also I would like to ask something else, when I decrease my guitar volume I hear humming noise,

when I 'll box it the humming noise will disappear?

Or should I put shield wire on input and output?

* What type of shield wire should I use?

Please send me links for shield wire.

Thanks a lot again.

Chances are high that boxing it will remove the hum, but perhaps not entirely. Using shielded wire may or may not help. Most of the time, we don't use shielded wire on a mudbunny build, but you could. Try Smallbear for Coax cable.
