here it is

Ok. Are they oriented like that on the vero ?
Did you check the line cut with this image ?
Something is very wrong with that sound, but it's not the voltages

I don't know. What kind of transistor did you use ? Did you check the pinout ?

Something is very wrong.
Check the resistors with a meter, all of them. Look at the vero to see if you skipped a cut or if there's a solder bridge

Thanks for your reply, I've been doublechecking for solderbridges and resoldered any potential dead spots but so far not resulting in more gain. Now I've followed the veroboard layout as included. I also added a schematic of the Violet variant, which I know might slightly differ in some component v...

I don't know what kind of sound you're after, but in my build i used 2n2222 hfe between 180 and 220.
It is very creamy and heavy, and it sounds much better that the others i had with higher gain transistor.
You should try

Do we know the voltages?

I forgot: my transistors are

Q1 = MP40B, 30hfe, 20mA L

Q2 = gt308b, 64hfe, 5mA L

Q3 = MP42 , 52hfe, 50mA L

I adjusted a few resistors and caps, and the Q3c voltage is like -8.05v I don't what to make of Q2C: it really depends from the voltage divider, so i tried 180k (-1,2v) and 430k (-5v); i don't know what i like more, i can't decide. Q1 is the strange one: it has very low hfe and leakage, but everythi...

Hi guys. Recently i was really into Doyle Bramhall II, and in his Reverb interview he talked about the Zonk Machine as a secret weapon. So i decided to build a Tone Bender MK1 just to see what it is. I didn't have fancy 60s transistors, so i used some russian ones. They say you need leakage for MK1,...

It looks like a Wampler Plexi Drive, kind of

Hi guys.
I was wondering how the filtering works on the HBOD.

What C7-R7 and C8-R9 do?

i can't find one locally. i would love to see a vero layout.

there's a reminiscence of a opamp big muff somehow. i would be curious to try one.

without tone control the guitar is gonna be super bright. and i would say that a splitted humbucker does not sound good

panasonic makes them in the fc serie, banzai is a great source in europe, and these caps are not so big after all

i finally built this pedal and i'm not sure i like it. it is kinda low gain, i was expecting much more..

you might be right. that cap looks pretty big. in the end this is a very tunable circuit.

so using the schematic posted earlier, here's a working schematic with the actual orange cap values for the eq and gain pot bypass cap: [ Image ] larger pic: http://johnkvintageguitars.homestead.com/Effects/Fuzz-ODs/Monarch/monarchschem-wOrange-eq-values-01.jpg actually c14 should be 1nf instead of...

mmm.. i don't know. i'm not an expert of mu amps, but if it's volume you are after you can act on the voltage divider on the output. if you want gain,personally, i'd go for the 330Ω resistor on the bs170. the point is that the eq cut a lot of signal (every tone stack does it), so we could place a 50...
