I think C2 is upside down. The positive leg should ho to 9v.

Re: JHS/EHX Lizard Queen
This looks a lot like the Zvex Machine. Machine has the same PNP + NPN pair but omits the 220p and 500k between the collector and base. It’s also got two non-selective frequency triplets between SHO stages. Lizard Queen is following in the same vein of other older effects that borrowed ideas. But ma...

Re: JHS/EHX Lizard Queen
And here is another example of proper attribution, this time by Benson Amps. Note how they give credit to Jack Orman for the pickup simulator idea. And by the way, their germanium fuzz is really novel and what I would consider an "original" design... https://www.bensonamps.com/guitarpedal...

Re: JHS/EHX Lizard Queen
I'm just bummed. The guy loves doing videos on the history of all these obscure people and companies, but can't champion or tell the story of the circuit and the guy behind it. Instead says it's "original". My point exactly. I'm not disappointed in JHS the company, who took non-patented, ...

Re: JHS/EHX Lizard Queen
That’s telling. Sounds like admitting that he borrowed from previous work is embarrassing for JHS, or at least they feel that way.jalmonsalmon wrote: ↑14 Apr 2023, 14:28 Funny thing, I put something in the YouTube post about the circuit and it was immediately deleted

Re: JHS/EHX Lizard Queen
Well idk... Kinda depends on what we see as the "picture" Is the circuit the picture or the sound? The circuit might look the same with some different values. And if we see that as the picture or say the creative outcome, it looks like a ripoff of something else painted with some slightly...

Re: JHS/EHX Lizard Queen
Funny that's my modded schematic of Tim's from my site. Also curious I sent a request to the JHS site to do an episode on Tim Escobedos work. I really wish Josh would just acknowledge Tim and the other diy roots. Seems a stretch to call it original. http://aaronlumguitar.blogspot.com/2015/01/new-di...

Re: JHS/EHX Lizard Queen
It’s not like they are trying to patent anything. He did say it was “original” and it is to some degree. To get the “100% transparent” merit badge he would have to mention Hemo and Tim Escobedo, but I suspect that would have been lost on a lot of people. It would be an excusable omission in ad copy...

Re: Frantone - Peach Fuzz [traced]
Here’s my build. I designed the PCB and had them manufactured at PCBWay.com it was $5 for 10 boards plus shipping. This sounds great. Easy to build and the parts are easy to get. I used the schematic post earlier by grrrunge and included the Zobel networks. I also added a couple pads on pins 1 and 8...

This is great, people should thank JHS for injecting some life into this forum! This is a good idea for circuit. I don’t think I can knock them for using these ideas.

Re: Retro Channel - The Fuzz [traced]
I just built one of these, sounds great. I’m wondering if there is something that could be done with the extra transistors? To be honest I’m not sure if there are any extra transistors. Looks like Q1 and Q5 are used to create a bias for the input of Q2. But I’m not sure how it actually works or if t...

@dylan159, one more question, I notice on the two stage pup vss of the 4069 is connected to Vr instead of vcc? Maybe I missed this if you mentioned it in the description.

@dylan159 I’m looking 2 stage pup, should the input or output of the unused inverters be tied to Vcc or vdd?

Re: PUP: a host of Perfectly Usable Phasers [documentation]
Thanks @dylan159 I’m always impressed with your work! It’s always thorough and inspired. Looking at the first two stage circuit I wondered about using the four left over inverts. Might be possible to use for an input or output buffer, maybe both, and two more for the LFO? Obviously is less than idea...

Here’s my build. I designed a pcb and had it manufactured at PCBWay.com. Making a pcb for prototyping has been my favorite workflow. The cost of 10 boards is $5.

Re: Small Time: PT2399 Delay with tails [documentation]
Looks great! Does this use a latching switch? Or is is a momentary? I think it should latching? But it’s a SPST.
I’m working on a PCB at the moment.
