One more question guys:
What changes need to be made to make the 4H version, besides the treble knob?
Thanks

Just finished my Model H 4 knob(no LED yet)
keep photos online
I liked the sound and will replace my mercury clone with this.
* already installed the LED.

Greetings,
What are the differences between the 3 knobs version and the 4 knobs version? I plan to trace a layout for it but I thought it would be nice to add the fourth control (treble). What should I add, eliminate or change according to the scheme posted in this topic?
Thanks in advance

Could I use 180k or 220k resistors instead of the 200k resistors?
If so, which value would work better?

Yeah, either value will work. 200K is a less common value. Everyone's got 220K's laying around.LooseCannon wrote:Could I use 180k or 220k resistors instead of the 200k resistors?

FYI. I recently revisited an old vero build of the Model H that I didn't box up. I remembered that I liked the distortion but the tone lacked some treble and the tone control wasn't all that effective. I looked at the circuit in LTSpice and found that decreasing 22 nF capacitor at the output of the first jfet (C14) to 2.2 nF improved the treble response and also made the tone control more effective. If you want to have the option to go back to 22 nF, you could put a 18 or 22 nF capacitor on a switch in parallel to the 2.2 nF, but I don't think it's necessary. I went ahead switched out the 22 nF capacitor on my old vero and it sounds great!
Hello, I am interested in this pedal, I have built the dyna red distortion and its great¡¡... I have the vero of this almost finished...
I would like to know if the biasing of the two first jfet is the standard at vcc/4,5 vcc? we have some voltages to check?
In the dyna red there is a 5458 that is working as a buffer, the biasing is at 1,4-1,8v, not the standard vcc/2, this is said by the man himself. I try to bias this 5458 at 4,5v and the sound changed, its not bad but the touch sensibility that this pedal is known for, dissapeared, so I let it in the intended way.

I didn’t bias either jfet but you could install trimmers (temporarily) and see what drain resistance sounds best.
I’m currently rebuilding my vero and can report my voltages when I get the opportunity.
