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 […]

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 […]

Building a Simple Op Amp Booster – Assembly

After the introduction, analysis and breadboarding of two op-amp based guitar boosters, I’ll complete the pedal. I’ll do the final schematic and bill of material, then do the soldering layout for a protoboard. I’ll plan out the enclosure, do some artwork and finalize the enclosure. I’ll finally assemble it and do test and demo. Final […]

Building a Simple Op Amp Booster – Breadboarding

After the introduction and analysis of two op-amp based guitar boosters, let’s see how they sound. I’ll breadboard them and try them out to make sure everything works as expected. I’ll give some effect characteristics, do a breadboarding diagram, then do the actual breadboarding (with bill of material) and finally test both effects out. Characterizing […]

Building a Simple Op Amp Booster – SPICE

I went through schematics for MXR Micro Amp and my Thunder, so now I’ll go through some SPICE analysis for them. I said the circuits are similar and should have pretty similar sound. Let’s see how they look when simulated and if we can learn anything. Schematics Here are the schematics in SPICE: The schematics […]

Building a Simple Op Amp Booster – Introduction

In this final build, when it comes to simple booster effects, I am going to use Op-Amps. An op-amp is an integrated circuit (a chip) containing several transistors inside of it to achieve a very large gain. But it does so in a way that makes amplifier design very consistent and predictable. In this post […]

Completed Prototypes for Thunder Boost

Last week I finished prototyping my Thunder boost pedal. I got boards some time ago, so I got onto soldering all those SMT components. The final result looks nice I think: The finished boards look pretty much like the 3D model in KiCad which is actually great. I was freaking out about soldering the components, […]

Prototype Boards for Thunder Boost

I just got some boards for my booster pedal design. I call it Thunder Boost. I’ll do a write up on it at some stage. This is my 2nd prototype board design – this time in SMT. I’ll try to assemble it in next few days. I ordered it from Aisler, the boards look good, […]
