Here’s my take on a simple two stage phaser similar to Phase 45. I called this pedal – Airmed – The Healer. For previous posts have a look here. As usual you can skip to the video and come back later for diagrams. The Healer? Airmed was an Irish goddess associated with healing. When king […]
And in true spirit of overdoing it, after playing with our phaser components, let’s look into LFO. For previous posts have a look here. As usual you can skip to the video and come back later for diagrams. In this article I cover some modding options for LFO, I do some SPICE simulation and then […]
This is getting a bit complex for a simple Phaser 😀. After a long way coming back to the original schematic, it’s time to do some experimentation. In this article I cover what might be useful to try out modding, I do some SPICE simulation and then I breadboard another version of the phaser so […]
It’s time to go back full circle … and actually go back nearly to Phase 45 clone. Well, turns out I was more off than I normally like to be on the original pedal 😅. If this picked your interest, keep reading, or as usual just jump to the video and come back for details […]
In the previous post I covered some details of the circuit similar to MXR Phase 45. A relatively simple circuit … but still with a lots of components😊. Ultimately it has only a couple of circuit blocks/components that we really need to look into. This time around I’ll be looking into choosing JFETs and tweaking […]
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.
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.
