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 […]
True bypass has been an unspoken must-have in DIY pedals world and sometimes buffered switching is looked down upon (for whatever reason). I personally hate wiring up 3PDT switches … soooo many wires. What if there was an option to do all the switching with just 2 wires and add a bit of high-end feel […]
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 […]
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 […]
This is the third post about switches. I already covered some basics about switches and what true bypass is. In this post I’m covering how to wire-up 3PDT switch – the most common stomp switch used in DIY effects. As always – video first, if you want to have a closer look at the diagrams […]
In my previous post I covered some basics about switches, in the follow-up post, I’ll cover wiring up 3PDT switches. In this installment, I cover what does a true bypass means. Actually, what options do we have to wire-up our DIY effects? I cover “always on” effect … ha! Then I cover “hardwire bypass“, to […]
This is a slightly overexplained series of posts about wiring up switches. Feel free to skip this if this is too basic for you. I’m just going through how to wire up some basic switches, namely SPDT, DPDT and 3PDT. In this post I’m going to cover basics and demonstrate how to wire-up switches on […]
I did a post on how to modify circuit from using NPN to using PNP transistors, and as a bonus I added a quick note on how to do this for Fuzz Face. Now it’s time to actually do it. I’ll breadboard a Fuzz Face clone, and then I’ll swap NPN transistors with PNP transistors. […]
After spending my sweet time going through a few boosters – it’s time to make them better. Adding some sort of tone control to a guitar pedal is a great way to make it better. In this post I’ll explore some of the ways to get a useful tone stack for your build. I’ll be […]
