Relay Bypass: final code

After the crowdfunding campaign, I decided to update the relay bypass code.

Indeed, this first version was nice, but one main drawback that was feedbacked to me is that the switch was activated on release, which was not always very intuitive or easy to handle. Moreover, I wanted to add a "temporary" bypass option in the Montagne Tremolo.

In this post, I am going to explain a bit the new code and to show you how I did it.

If you have not read my post about Relay Bypass, I highly recommend you to read it before reading this post. All the basics of microcontrollers are presented there.

  Tip! The full code is available on Github. With the relayonpress.c and header.h files, you will have everything needed to code or burn chips.

If you already have a GitHub account, you can Star the project for updates, or Fork it to modify it and make your own Relay Bypass code.

Lets go!

Hakko FX888D: a $100 high quality soldering station

Let's face it: your good old soldering iron is not always the best pal to work with.

I had some troubles with mine: no support to put it when I busy doing something else than soldering, which can be quite dangerous if it falls or burn something. Moreover, the power cord was quite short and not very flexible, so it was not always easy to find a good "spot" for it in order to be perfectly comfortable. Finally, it takes a long time before getting hot enough to solder, and 30W is sometimes a bit low to solder big potentiometer or jack legs.

So I decided to invest a bit in a soldering station.

After reading a lot on the web, I have found this little gem: the Hakko FX888D, a Japanese soldering station that you can find for $96 on Amazon

Here is mine:

14 electronics suppliers for guitar effects (with pros and cons)

Finding good electronics suppliers is a key issue when building guitar effects professionally. Indeed, they play a huge role in traceability and quality of the components (where the components come from and what they are exactly), and also the price of these components. Sometimes, they can also add delays if they are bad with handling orders and shipping it quickly.

Goods electronics suppliers are the root cause of a good build quality for a pedal builder.

With my crowdfunding project, I have an intermediary position. I cannot order directly from manufacturers (because I would have to order thousands of units at least), but I can order from electronics wholesalers!

Already 95% of the components have been ordered, and I already received quite a lot of parts! Here is a picture of the switches I got this morning (more pictures will follow in a next post):

Create your own pedal company: good or bad idea?

If you already have made a few pedals yourself, you surely have thought about selling them or at least build some of them for other people. Create your own guitar pedal brand seems like a good idea on paper, however there are many pitfalls.... Lets talk about it!

Disclaimer: I make effects myself, and this post is not intended to "kill competitors" (with my 30 pedals a year...)! On the contrary, I think it is way better to be transparent and to talk about it: this is only my opinion, and feel free to express yours in the comments section :)

It is a complex matter that is not always easy to discuss peacefully because of money, and there are many different opinions on the subject. It is also the source of really long yet exciting threads on DIY forums (check this one!). The simplest option for me is to discuss it from my point of view as a builder. Thus, I will talk about Coda Effects, and well, just once will not hurt, about me, and give you some tips if you want to jump in it!

Early 2013, I started to show interest in guitar pedal building: after opening a Fuzz Face, I was quite astonished by the simplicity of the circuit (there is almost nothing in there!), and I realized that building guitar effects might be simpler that I thought.

Relay bypass with anti pop system: noiseless and clickless true bypass

Did you like my post about relay bypass? At least I did, and now I use it in almost all my pedals! Thus, they are longer lasting, and we avoid the mechanical noises of a 3PDT. However, I noticed something annoying: the relay bypass makes more "pop" noises than the 3PDT, especially with high gain circuits...

Indeed, relays tend to switch from one state to another much quicker than big mechanical 3PDT switches, which causes the "pop" noises to appear. The gainier the pedal, the more it will amplify the pop and make it louder.

So I adapted a system that I have found on Stompville that suppresses all these noises. Here is the result, with a (very) simple "before and after" video:

Ultimate guide to guitar effect wiring: how to wire DIY guitar pedals properly?

Your guitar pedal circuit is finally populated and ready to rock! However, you still have to solder all the wires... I noticed that it was during this step that beginners encounter most of the issues that go along with guitar effects making. Especially with veroboard, you can quickly get a huge mess of wires going everywhere in the enclosure, with the so-called "spaghetti wiring" that we all achieved at least once when starting to make guitar effects!
