In the last post we covered how to measure variable resistance of the NSL-32 optocoupler. Now it’s time to use it. In this post I’ll cover using it in the pre-existing breadborded Phase 45 clone, and I’ll replace JFETs in it. What started as a simple Phase 45 like adventure is now the 8th post […]
What I’ll cover here is using opto-couplers as variable resistors, because that’s what we do in pedals, right? Why use them for their intended purpose? Well, this NSL-32 optocoupler I’ll be using, in fairness, has “passive resistance output” as a feature. CLM6000 was commonly used in pedals, but that one is long obsolete. NSL-32 is […]
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 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 […]
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 […]
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, […]
