Perfect artwork for a perfect name :love:

Try and see here to compare diodes Vf. But D9E are totally fine, just like any schottky would by the way, do not pay attention to "harder, bright, smooth, warmer", or any other hype words Gemini is repeating from legends and myths spread over the internet about diodes, especially germanium. The...

Maybe the taper of the gain pot?

stumbled upon this post while binge searching for gear oddities: "Buckle Up: There’s A Definite Decline Coming For The Guitar Gear Industry" I did see a couple of fellow builders posting about closing down this January... Sad...

Yup, I can confirm that, I solder them on the board and mixed up with alphas there's always a tilt, I decided to embrace it and tell people this has a great influence on the sound, warmer, more dynamic, more (insert your sales keyword here)..

all at max, triangle in pink, ram's head in green, civil war in blue, green russian in orange. I'd go for ram's head and triangle just because I have never built any 😅

Tayda all day long 🤘

You should check out the diode comparison that @thomasbe86 put together. Suffice to say, the difference between the 1S1588/1N4148/1N914 probably won't be noticeable: Thanks @PedalBuilder ! I put the data in a more user friendly interface here easier to search, filter, etc. Oh and I added the...

Tube screamer was my first ever attempt, and second, and third,... Back in around 2004, a friend and I spent about 8 hours to put one together on vero board.. so excited to test the result, plugged it in, no sound, started to smoke here and there.. Had forgotten to clip the leads of every...

That is definitely the kind of haunting smell that I hate, a reminder of all my failed attempts...

That is EXACTLY the kind of thing that can hold me back! Sometimes I really start to question myself if I don't give up on these things, it really feels cursed, like no matter how simple, I will not make it work!

I love you guys but I do feel a little better knowing I am not alone :) It is a mid thing, like MF1 of the Amek Mozart MZ15-RN, just keep making silly mistakes like powering it up with 18v with 6.3v rated caps was the last straw today... WLCSP is way to small for my aging eyes, any good...

Hehe, nope, by law in Switzerland you need your business address way too visible on your website, so it is public 😉 My legal expert (wife) reminded me that I am not allowed to post full schematics though 😅 Anyways, point being, what is your nemesis project?

What is the one circuit that you have been working for way too long and keep failing at delivering what it should? I had planned to release this new model for black friday, and again, for the 20th times in 20 years, I made silly mistakes with the prototype and it sounds absolutely nothing like...

I would add that your potentiometer should be 50k, so at minimum it would be unity, anything above adds gain. or you would need to swap the resistor in the negative feedbakc loop to 500k. Have a look at how gain is calculated here: https://fr.farnell.com/op-amp-gain-calculator
