I finished building a simple JFET booster over the weekend. I had to do some extra designing of a JFET amplifier to make it boost since the breadboarded version wasn’t boosting the signal. The design is only slightly more complex than previous efforts. You can check out the dedicated build page here.

Building a JFET Booster
The next in line for building is a JFET Booster. I chose a Fetzer Valve circuit. This one is a bit different, I had to go through measuring my JFET components and then go through calculating correct component values. I then breadboarded it in two different versions. It was interesting, something different, check it out.
I finished building a simple MOSFET booster today. Simple but effective pedal, clean boost with flat response and great input/output characteristics. Or check out dedicated build page for it.
I started building a simple MOSFET booster this time. BJT booster is done, and now something a bit different, but similar enough :). I chose AMZ Mosfet Booster. I’ve done analyzing it and breadboarding it, so have a look.
Finished Building LPB-1

And this is it, finally, the pedal is finished. After breadboarding it, then experimenting some with the effect, settling for final list of components to use, last time I finished the enclosure. Today, I soldered it and finally assembled it into it’s final form. Check it out.

After testing it and experimenting with simple booster pedal, I decided which components to use. Now is time to finally start putting everything together. Lets prepare some colourful enclosure for this pedal. Check it out.
Choosing components for the booster

Next step in building the LPB-1 effect is choosing components. There is a number of choices needed to finalize the design: enclosure choice, protoboard or PCB, powering the pedal, jacks, pot etc. Check it out.
Experimenting with the Booster

Following the first article, in the new article I’m going through several different transistors and trying them out in the original circuit. The whole point of having a breadboard is to be able to experiment with your creation. Have a look, and I hope to follow up soon with the next step – choosing the […]
Hello world!

Hello everybody. With everything happening in this crazy 2020, I got back into playing guitar and actually got interested into guitar effects. I tried some DIY guitar effects and thought to share some of my journey through this exciting world. Hopefully I’ll learn some more along the way and at the same time I hope […]
