Using Relays in Pedals

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 […]

Clíodhna – PCB Version

All the work is done for our Super Screamer, or is it? What if I do a PCB version of this, just for fun? PCBWay said they’d gonna send me some prototyping boards for free right around the time I was finishing the pedal. So I said why not, let’s design a PCB version of […]

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 […]

Clíodhna – Finalizing the Circuit Design

Let’s finish the circuit design today. The first and the second part went pretty well, I also covered tone control for the pedal. Let’s add couple more options and then finalize the design with actual switches I’ll be using. You can jump to schematic which is just below, or to the finalized circuit schematic. I […]

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 […]

Clíodhna – Tone Control

So far so good ?. The first and the second part went pretty well. Let’s plough on. In this post I’ll cover tone control. The previous parts were dealing with clipping section – clipping and frequency response shaping. I conveniently omitted tone section. Now it’s time to add the tone stage. You can jump to […]

Clíodhna – Super Screamer Pt2

I think that the first part went pretty well. Let’s continue designing our own DIY overdrive pedal. In this post I’ll cover various clipping options. The previous part was dealing with clipping section too, but it was covering frequency response shaping. This one will cover the actual clipping. You can jump to schematic, or breadboard […]

Design Our Own Super Screamer Like Pedal

After covering a lot of ground around Tube Screamer like pedals, I think it’s right time to try our hand at doing some super mod heavy design of our own pedal. In several steps I’ll try to design some DIY overdrive pedal that will have all the character of a Tube Screamer but with much […]
