That's more or less how that works it. You can use the non inverting calculator here https://circuitdigest.com/calculators/op-amp-gain-calculator to figure the gain and then convert it to DB gain using this https://circuitdigest.com/calculators/decibel-db-calculator. That being said I think...

I have been thinking about this whole shielding/ground loop thing a fair amount recently. It at first seemed a little abstract but I think the noise comes down to the following areas. Antenna. Although possible none of our equipment other than say a cable which is improperly wired makes a...

I agree it should have a ton of gain. I would double check R6, 10, 11 and 17. If those are all correct and you are left wanting more gain maybe change R10 to a trimmer wired as a variable resistor. A 5k or 10k would probably be good.

I’m wondering if you still have some solder issues. Some of the joints look starved to me. I try to get the solder to basically come flush with the pads on both sides of the board. It makes the inspection really easy, from the top of the board. This is kind of what I aim for. For the...

Mine sounds a little different with full gain vs full volume but neither would I really call dirty. I can get some breakup with both on full but that might just be because I am boosting the next stage. It took me a bit to find a power supply that worked well for mine. I couldn’t run it off my...

I finished redrawing the component foot prints that were bothering me. Added a capacitor and reworked the layout to make it cleaner. While I was at it I also redid my 3PDT bypass board. I'm hoping it works better with the crimped connectors I have been making. I'm going to sleep on it and...

That makes sense looking at it and with the explanation. I think I want to start to learn some of the simulation software so I can better understand some of the filtering stuff. I appreciate the reply.

I have been thinking about trying CircuitLab to help with a few things I’m working on. Do you have any more feedback on how the month has gone for you?

Not that it matters here as the low pass is set at a pretty high frequency and the filter is there also. Does the order of the resistor and cap affect the following high pass filter. Would I calc it as a 2k5 into 3n3 with a cut off of 19.2Khz if the resistor comes last and a 1k5 into 3n3 with...

Today's chapter is research. I found as many Rat schematics as I could. It appears the biggest difference is the order of the capacitor and resistor following the OP amp. Any idea if it makes a difference? Aside from that I may add one resistor before the volume pot. In case anyone is...

The blue is my favorite, then yellow. I don’t dislike the red but it is more subtle. Need a green and black for all the YATS and Rats.

Got my the prototype working. I somehow botched the volume knob layout and it works opposite the direction I intended but other than that it works and sounds fine. The noise floor is decently low for what it is. I used my new crimpers to make the connections throughout. I think I will...

Yeah I think I may size them down a bit and make the resistor holes a little bigger.

I think the rat might be my favorite pedal. I want to like all the kooky or fancy pedals but at the end of the day I always go back to the rat. It into a peavy classic 50 was my sound in my 20s. I built a rat with a ton of switching options https://forum.pedalpcb.com/threads/hella-rats.20070/...

I thought that looked like a jumper. Is it an LED?

I’m not 100% sure but I think you leave the LED unpopulated if you’re not using it. I think the way it is now might be dumping + to ground. Is it when it touches the enclosure at all?

I agree with @Nostradoomus . I think it’s right here. Sometimes if it’s a tight fit I will turn that jack 180 to make the input closer to the center. I think jacks like this are easier as they are not exposed on the sides...

Mine took a bit to get going right also. I initially had all the ICs in with the notch up and one of the charge pumps in the wrong spot. It’s a cool pedal once it’s going.

Well I mush have been good this year. Santa left me these along with some other tools in my stocking. these work 10x better than my old crimpers and get pretty perfect connectors in 1 go. I need to fine tune the stripped length and process some but this is the 3rd crimp I made on 24 gauge...

https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-low-pass-and-high-pass-filter With that you can calculate the corner frequencies for high and low pass filters. I found a lot of the electro smash articles very helpful to learn what everything does. Then you...
