This latest post is a brief illustration of the process of a pedal build from start to finish. It covers the making / purchase of a project board, the gathering of components, the soldering and ultimately the satisfaction of the build and the results with an amp!
To start off, this is my component rack on the bench in my shed. By some builders standards this is a small unit of component drawers (40 various sized drawers), but for me just starting out its just right. The top two rows are labelled for resistors, Ive got drawers set aside for common diode types, capacitors, ICs, jacks and usual hardware bits such as switches, sockets, LEDs, bezels, hookup wire, solder etc.

I went round the office the other week looking for empty business card holders. Why? I quite liked the idea of gathering all the parts for a particular project and keeping them all in one place so when I come to work on it everything is right where I want it. These holders are just right for putting all the pots, caps, ICs etc in so stock picking at build time is pain free. This box is all set up for Madbeans Firebomb PCB. Go to the project pages here to find out more about Brians amazing work. Suffice to say Brian is a genius is this field - his understanding, depth of knowledge and expertise are second to none in my opinion. Hes developed a quality range of projects that cover some of the classic pedals, some great boutique pedals, some mystical ones and some truly innovative designs too. Take your time to look around his site and forum to get familiar with his handiwork.

This is what Ive stuffed into that box so all the parts are there in none place. Makes life much easier when youre ready to go IMHO. I source my parts from a number of suppliers but being based in the UK Ive come to rely on the great service of Doctor Tweek (aka Steve). Hes got a mass of stock, priced great, ships fast and is always on hand to help out with any questions. A very accommodating bloke, check him out here.

Parts all in one place |
Below is a perfect example of Brians handiwork in developing this double sided PCB. Its clean, compact, very clearly laid out and very well labelled. For a dummy like me its just like painting by numbers - the board tells you what to get and where to put it. Soldering by numbers really!

So heres the board with all the resistors loaded and soldered into place. Ordinarily Id solder IC sockets or transistor / cap sockets first, but there are no ICs in this particular circuit and the values of the caps and the transistor types are not too critical to the sound so you can go ahead and solder them direct in place. The next step after sockets is to solder resistors. And here they are:

Next Ive put in the capacitors and the diodes. The final bits to solder are the transistors as theyre delicate and prone to damage so you want to apply heat to them in short bursts.

Caps and diodes soldered into place |
Lastly Ive soldered the two transistors in place. This PCB is suitable for board-mounted pots which you can see here. Alternatively you could just wire in the three wires per pot for off-board wiring. Ive also soldered in all the other wires (input, output, 9v, ground, indicator LEDs and switch wiring) ready for boxing up.
NOTE: Theres a reason its a good idea to get everything as ready as you can pre-boxing up: SO YOU CAN TEST BEFORE BOXING! You want to make sure the thing works before you box it up. If it doesnt work, you can troubleshoot before its all buttoned up in place. If it works, then you box it and it stops working, your troubleshooting will be more focused to that point in time. Also trying to troubleshoot when the circuit is all neatly boxed up is not ideal, especially if you have to start unwiring, de-soldering or removing components.

All done - transistors and pots soldered onto the board with offboard wiring in position |

This is one amazing sounding board, boosting my AC15 just nicely! Ill look at other projects and different types of boards in future posts.
