- In this video, we go over 5 kinds of boost circuits that are commonly used in Guitar Pedals, show how they work, and see what the pros and cons are for them.
We've already covered a few in more detail.

This new fundamental series is very educational and useful. As always, amazing content! Looking forward to more.
Amazing series of videos, before this i had to search all over the web to get this knowledge in bits. Please keep up with them! Cheers to everyone involved.
I love this building block explanations. They are very useful
Awesome! Good explanation of how circuits work. It motivates me to get my soldering iron and do some stuff
Great post! I am always interested in boosts that increase VOLUME at the expense of clipping and distortion.
Good timing, I have a distortion pedal on LTSpice and I wanted to add a boost to it. Thanks Erik
No prob!
Well done. Maybe the boss-mt2 analysis?
Fantàstic explanation!!!
Thank you sir. I'm going to spend some time going through your videos.
You may have covered it but I've yet to find a discussion on designing an expression pedal interface. Specifically I'd like to make a korg mr.multi in a Hammond box with an expression pedal jack.
CMOS circuits do make good boosts but I prefer to use them like amps, set them to low gain and run other things into them like compressors, boosts, rat etc.
quality content. thanks.
Thank you
I do like these videos as I've finally started to learn electronics. even if I don't understand the why's, the how is still fun.
No worries. Every journey starts with a single step.
Awesome stuff, it’s a good refresher to get back to the basics. You should do a video on tone controls if you haven’t already! I’m sure you could easily go through 5 different types that are commonly found in amps and pedals.
That's coming up, but I want to be more detailed on those. Lots of nuances.
You thought about the bass, THANKS MAN !!!
Wait till you see our new Bulldozer pedal. Designed around the bass.
thank you very much!
No prob
Any documentation on that kind of CMOS setup?
Would be nice if you had a link to download the circuits
cool
with the cmos schematic at 12:40 i believe the p-ch mos is upside down. was this intentional?
It was. Easier to draw in LTSpice.
Hi, I’m kind of new to making pedals and I’m confused as to why on the second Pedal/type of Pedal (J fet boost), why are there two inputs, and why is there two different circuits on the same schematic, like why are they split? Love these vids btw!
You might be referring to the voltage supply in LTSpice. I have it provide a "voltage supply" for the input that is an AC sine wave of about 0.100 volts, or 100mV at 1 KHz. 100 millivolts, because for a single string note on a decent pickup should generate about that much voltage and 1 KHz is a good benchmark frequency for guitar and bass pedals. So the "input" on the left is that. The "input" on the right is where I am "plugging in" that 1 KHz signal. This is the virtual equivalent of plugging my guitar jack into the pedal.
I hope this helps. We go over this a bit in the LTSpice videos.
@@erikvincent5846 Ok, so if I were to try to build it on a breadboard would I ignore the section on the right and just start from C2? Like input into C2 etc?
@@marcorosella88 Keep all the stuff on the right, C2, R4, Q1, R2, R3, C3, and a 100K resistor as a pull down to ground to simulate your volume pot.
@Erik Vincent Ok, thanks!
Skeletor!!!!
Why are you using a *mmbz9v1al,* (which has 2 diodes) when your only using 1? Seems like a waste!!
It's the only 9V zener SPICE model I have in LTSpice and I am too lazy to make another.
I'm waiting for you to make some videos. You got a great screen name and would love some Raspberry Pi and Arduino videos, especially some C compiled raspberry pi projects instead of Python ones. Or some good AVR-GCC tutorials on a raspberry pi, being the ultimate open-source development rig.
@@erikvincent5846 - I'm thinking of changing the name, because I mainly restore old Tube Radio's & Tube Test Equipment.
