Hybrid Overdrive!? "FET Hack MOD" Adds FET Clipping To An Op Amp Overdrive!

FET vs Soft Clipping • What's The Tone Differ...
Today we are looking at a fun mod idea to get that "crunchy/chewy" Marshall Plexi, Tweed Bassman type tone from an op amp based overdrive circuit.
I don't know if such a circuit exists in a pedal today, but we are adding a JFET stage at the end of an op amp overdrive, just to use it as a clipping transistor and get those FET breakup tones. If you've made your own breadboard overdrive, I invite you to do something similar and have fun exploring different tones from that circuit!
Thanks for watching, I hope you enjoy the video!

Brilliant. I will add this to the "old" breadboard overdrive and add a potentiometer to the jfet to crank it. Thanks again 🎉

Hi! Thanks for kind words! Great to hear you enjoyed the video, hope the like the FET mod! 😃

[@user-to1se1hj6g]

I just discovered your channel. I really enjoy it. You are doing some interesting and fun videos. Keep it up!

[@arito]

Thanks for watching! And thank you so much for the kind compliments! It's really nice to hear that you enjoyed the video, I appreciate it!

JFETs and MosFETs really shine in soft clipping/light overdrive circuits imo.
There is a website that has many jfet based guitar circuits. They have circuits where the jfet is used to try to get tube like distortion.

Thanks for watching! And thank you for sharing your thoughts and impressions with us! I have another video comparing discrete FET pedals against a soft clipping op amp circuit if you're interested: ua-cam.com/video/__sryGI11E0/v-deo.html

Hi arito, I'm passionate about electric guitar and electronics and your channel is fabulous. For the 5th year I wanted to bring as a project some guitar effects in order to have opamp, jfet as an argument

Thanks for watching! Great to hear you enjoyed the video! Hope your project works out!

I think I still like the MOSFET pedal more, so I'm going to be really interested to see the answers, and whether or not I was right. Still, it's pretty cool how much you can change the character of the JFET design just by altering the resistors.

Thanks for watching! If you heard a difference between the clips and have a favorite, please share your votes! I'd really appreciate it!

great video . I very like part to listening different effect, unfortunaly i 'm not a guitare player.... but i love electronique and pedales are a great experimentation subject. your explanation are great.
Question: what is voltage level at pedal input and output ? and it seems you use stereo jack , why ?

[@arito]

Thanks for watching! Great to hear you enjoyed the video! The input voltage will change depending on the guitar pickup. But, I think anywhere between 0.1V~0.3V is pretty average, although some hot pickups might output 0.5V. Output will depend on how the volume pot is adjusted, but the signal coming out of the JFET will be around ± 4.5V, for a 9V power supply.
The stereo jack was only because that's all the shop had available in that format/shape when I bought it. So, I have it connected like a mono jack. Hope this helps!
