Tutoriel: how to prototype with a breadboard

Prototyping is not always an easy task with guitar pedals. One solution is to heavily mod an existing pedal. But what if you want to start from scratch? How to test things before designing a circuit and solder everything?

Well, we have a simple solution for that: using a breadboard!

Let's go! In this blog post, we'll see why the breadboard is such a cool tool and how you can use it to design and test your own circuits.


Make your own DIY power supply: yay or nay?

Let's be honest: buying a power supply is not the funniest thing ever.

It is quite expensive (and I have to admit that I would have prefered to add another fuzz that I do not need a nice pedal to my pedalboard than a power supply! 😁) and differences between the several models on the market is not very obvious...

So I asked myself: is it possible to make a DIY power supply?

In this blog post, I will explain how a power supply work, what are the good criterias to choose one from an electronics point of view and if it is a good idea to make one yourself. Let's go!

JHS Superbolt clone PCB and the missing JFETs

Hello solderers and pedal maniacs!

Here is my last build: a JHS SuperBolt clone! As you may know, I have already did a clone of this pedal, but I have finally designed a PCB for it!

Here are some pictures:

I used a Supro logo that was laser-cut with some double tape to make the "Supro" sticker. I think it makes a really nice look!

Why I publish my circuits schematics (and why you should do the same!)

When I made my first commercially available pedals, I chose to publish the circuit schematic online. Transparency always has been a missing thing in the guitar pedal marketing world, so it was a very natural move for me.

However, when I spoke about it with friends or colleagues, they all said to me: "why would you do this? You undermine your business by publishing everything!"

So here are my answers about why I think being transparent is a must when making guitar pedals, and why I think you should do the same if you build guitar pedals.

The different types of diodes

There is a very common marketing point that we see all the time with "boutique" guitar pedals: the famous vintage ultra-rare licorn-made type of diodes! Germanium diodes are often associated with a vintage and warm tone, whereas silicium diode sound harsher and fuzzier...

Time for a blog post about it!

What is a diode? How do they work? Which one should I use when making guitar effects?

Univox Superfuzz (from the 70s): history (post 1/2)

People say that I worship the Univox Superfuzz a bit too much, but they are wrong. If I could, I would already have started a sect about this pedal!

It is simply my favorite pedal of all times! First because of its amazingly cool look with the huge "Super Fuzz" rubber pad, and also for its sound that is crazy loud and heavy. Seriously, best-fuzz-out-there!

After seeing Fu Manchu live in March, I could not resist buying one. After selling a kidney on the black market, I was quite lucky because I found a non-working unit on ebay that I could repair by replacing a few electrolytic capacitors.

The Super Fuzz is really the ultimate fuzz for me, so I decided to honor it by writing the most complete article about it. Here is the first part!
