Airmed – My Take on a Simple Phaser

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 […]

Simple Phaser – Playing with LFO

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 […]

Simple Phaser – Experimenting with All-Pass Filter

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 […]

Simple Phaser – Going Back Full Circle

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 […]

Simple Phaser – Choosing Components

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 […]

Breadboard a Simple Phaser

I like watching That Pedal Show on youtube from time to time. Their video What Guitar Pedals Should I get First? is suggesting that my first three pedals should be some sort of distortion, modulation and time based pedals. I should’ve said – spoiler alert … too late now. As suggestions go, they are matter […]

Reverse Polarity Protection

Here’s another post in the “basics” series. This one is about reverse polarity protection. Guitar pedals have a peculiarity: they are powered by a center negative supply . I only encountered this with guitar pedals, vast majority of other power adapters have center positive supply (it’s just how the cable is wired, I’m sure there […]

Wiring up Battery

This is a short post about how to wire up battery for a DIY pedal project (if you wish to do so). Here’s the wire-up diagram: Guitar cable is mono cable – there are only 2 wires. Tip is carrying the signal and sleeve is grounded. If we were not using battery – just omit […]

Modding MXR Zakk Wylde Overdrive

Continuing coverage of Tube Screamer like pedals – I’ll cover a sort of a Boss Super Overdrive clone. I’ll be covering MXR’s Zakk Wylde overdrive (ZW44). This post continues building on previous posts: breadboarding the pedal, how it shapes the tone and I even did an alternative version. I have already covered SD-1 too. I’ll […]

Tube Screamer Like Pedals

Now, let’s talk about Tube Screamer like pedals. Maybe not in the sound but more in the circuit topology. In this one I’ll be covering Boss Super Overdrive – SD-1. This post continues building on previous posts: breadboarding the pedal, how it shapes the tone and I even did an alternative version. To be honest, […]
