Thanks Chuck!! Its only that I was getting the impresión that in my build the treble gets a lot more fizzy than in the demos.. sometimes I have Saw that they put he control in the last quarter and the tone is not much trebly, and with single coils!!! I am using humbuckers... Could be a taper...

to all the people that have made this... its normal that the treble control gets very, very trebly in the upper half??, its unusable in that positions, which cap set the limit freq?? I dont know if i have soemthing wrong... in the videos in yt look like with the control up dont get fizzy at...

Idlebeach, very nice build!! One question to you and all other people who built this pedal... did you measure the hfe of the bc549c did you use?? Thanks!!

Hello to all¡¡¡. The fuzz is working¡¡ Thanks for the help and responses¡¡¡¡.....the bias of q2 wasnt the problem, I resoldered again all the board and conections and voila¡¡ sound pretty good¡¡ ... two observations, there is noise with the gain up, i would say that there is too much noise, I...

Thanks Robert and Chuck¡¡ One question, with the r9 to 1 meg mod, what is achieved? the vc only up to 1,8 Sure its a bassy design, but its very easy to solve this, you can low the 0,1 caps between q1 and q2 to taste.....

Thanks for your answers, Jesúscrisp and Robert!! Ok, this the confirmation that I was looking for, this voltage is normal with this configuración, so I have to look elsewhere for the problem!!!

A transistor has to be biased, sometimes high or sometimes low, but It has to have a VC between 1-8v ( assuming 9vcc). The things is that bipolar are very consistent, nota like jfet, germanium etc so if you built the circuit, the most probably is that the bias is right All the information i have...

Thanks comradehoser¡¡ yes, the pyrocumulus its based on thorpyfx fallout, but in the fallout, the three first stages are exactly like the dice work muff diver.. Have you checked the voltages of the transistors? I would like to have a reference. Mine dont sound ok, it have very low volume and...

Hello to all, I built the pyrocumulus fuzz, but I have a litle problem here, the vc in q2 ( or q3, the second stage from the input) is low, like 1,2 v, isnt in line with the usual 4,5v. The rest of the stages are properly biased at 4,5v. This circuit is directly "inspired" by the dice works muff...

I am so glad that this have worked!!! Fizz gone?? Wow...I wonder what was happening when this cap were between rails. Why you dont try the trick of the resistor on the pot?? Before this try to put a buffered Signal on the input of this pedal ( Boss pedal in bypass..etc) to see if the squeal is a...

When I put the wires to try It I Will report to you my finds

There is a mistake on the 7660, between the pin 5 and 8 there is a 100n CAP, It has to be between pin 5 and ground, its the CAP that is parallel to the 100uf CAP (yes, you are right its far away in the tl072 negative input) Also i would remove the 2m2 resistor in the input , its mangling the...

Have you look at the schematic? I think I saw several mistakes in the vero layout, the -v don t have the 100uf filter and other things..

Sorry to hear that¡¡¡ When you say that it was sounding worse than before, you are talking about noise? or tone? if its tone its weird, you are using the same values...The funny thing is that I bit the bullet and I am building this vero too¡¡¡:ROFLMAO::ROFLMAO: I like very much the tone on the...

With veroboard layouts I always notice that there are strips that are longer than necesary and this can bring feedback-squealing-impedance issues. A good practice is to do cuts where applicable to isolate parts of the circuit.. ex. a strip with a input signal that goes all the way the board...
