What took you so long? :LOL:

Maybe you should have used real octopus ink. Authentic art! Our daughter had some great art teachers in high school. Two of them built a glass-blowing facility. The only high school around that had glass blowing. The students crank out some beautiful work. Each year they hold a Christmas...

There are two things that will make an opamp clip asymmetrically. 1. The output of many opamps cannot swing to either rail and the output voltage range is not centered between the rails. 2. Input bias current creates a voltage drop across the feedback resistor, causing the output to not be...

HamishR emailed me a few days ago with a mod to the Eliminator (PPCB Recycler) OD. The Eliminator bears a strong resemblance to the M.I. Audio Crunch Box, with the LED clippers deleted. Missing Link added a Vref buffer & output buffer, both of which I consider unnecessary. HamishR added the...

Here's the latest update. I added S2, C20, C21, R16, R17 & TR4. Nothing else except the notes changed on sheet 1 and nothing changed on sheet 2. If you turn Fdbk Trim up enough to cause oscillations, IT WILL GET LOUD. I might add a pair of clipping diodes in the feedback path.

Should not be noisy. There could be many causes and this is not a troubleshooting thread. ;) In other news, I tried adding feedback around the BBD like we would find in a flanger. Very interesting. It magnifies the vibrato effect and with a lot of feedback, we get that "talking thru a...

Your Low tide contains a PT2399? :oops: Mine has a V3207D BBD in it and is dead quiet.

In chorus mode, the LPG is barely noticeable. Which is how it should be. But in Vibrato mode, the LPG should do something obvious.

And here it is: The Heavy Water Modulator. I had considered some other names, such as Swamp Water, Mineral Water, Toilette Water and Bong Water. To really complete the Heavy Water motif, the enclosure should either be day-glo green or glow in the dark. The parts count is significantly reduced...

Who says ChatGPT is bullshit? It drew this for me.

Yo Fig! I'm still working on the artwork for those pedals, honest!

That post is over two years old and you are the first person to notice this, good catch! The text has now been corrected. Now I'm the one who's embarrassed. 😜

The fact that everything connected to Vdd draws current and that current contributes the voltage drop across the DYNAMICS pot.

Yes. We're starting to drift off-topic.

That's right, U2A boosts the output of the distortion stage. Comes in handy if you want to set DRIVE low enough that the circuit runs clean. That opamp could be replaced with a BJT, but I would not recommend it because we need a low output impedance to drive the Baxandall tone stack. I know...

Setting the LPG Trim is easy and a matter of personal preference. According to the Shallow Water Manual: "The recovery filter’s lowest frequency can be adjusted, to fine tune the way it will react to incoming signals. Lowering this frequency emphasises the action of the low pass filter...

It's easy enough to boost the 5V signal coming out of the TINY25V microcontroller, although it's not really necessary. The CD4046's VCO IN pin is analog and the VCO tuning range is not affected much by power supply voltage.
