MXR Distortion Plus on Breadboard

MXR Distortion + pedal has been around since 70’s and featured in many 70’s and 80’s rock and metal recordings (and many more modern ones). A true icon, used by likes of Dave Murray, Randy Rhoads, Slash, Tom Morello and many many others. Iconic, sounding great, yet simple, great for DIY effort 😆. Let’s build […]

Silicon Fuzz Face – PNP Version

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. […]

Building a Fuzz Face Clone – Assembly

After the introduction and analysis, then breadboarding and experimentation, 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, and finalize the enclosure. I’ll finally assemble it and do test and demo. Final Schematic Trying out different things last […]

Building a Fuzz Face Clone – Experimenting

After the introduction and breadboarding it, let’s see if we can get a bit different sound. Fuzz Face had lots of different versions throughout time, a testament just how tweakable the design is. I’ll explain some possible experimentation that can be done with the effect first and I’ll just jump straight into trying various options […]

Building a Fuzz Face Clone – Breadboarding

After the introduction let’s see what’s the sound of the clone is. I’ll breadboard it and try it out to make sure everything works as expected. I’ll do a breadboarding diagram, bill of material and then do the actual breadboarding. Finally I’ll test the effect. Breadboard Diagram Here’s the Fuzz Face diagram once more: It […]

Building a Fuzz Face Clone – Intro & Analysis

In the next couple of posts, I’ll build a guitar fuzz pedal. More specifically – a Fuzz Face clone. It is a simple, yet, iconic pedal. It’s been out there since ’60s. Used most famously by Jimi Hendrix, but essentially used by many others like Gilmour, SRV etc. Even more specifically 🙂, I’ll be doing […]

Why Boosters and What Next?

After finishing four different DIY boosters, natural question is – what’s the fascination with them? After all, they just boost guitar signal, not much more. Come to think of it, maybe I should’ve asked myself this question before I started building them, but here we are and better late then never. There are several reasons […]

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 […]
