My past few pedals have all been based on a kit that I buy. It comes bundled with all the components I need as well as a PCB board that determines where all the components go.
This pedal I built from scratch. I saw a schematic and layout online and built it based on that. I bought all the capacitors, resistors, pots, switches and wire. Its a step forward in my learning of electronics.
The pedal is called the ‘Highway 89′. It is an overdrive pedal loosly based on the Dr Z route 66 pre-amp. The first thing I did was wire it all up so that I could debug any problems that may arise. So all the pots and jacks are just hanging out attached to wires.
Once I made sure all was OK I drilled out the enclosure I bought. To do this I put masking tape over the paint of the enclosure. I then used a punch to create dimples to center the drill bit. I then drilled a pilot hole and proceeded to make it larger with a step bit.
The next step was to secure all the pots, switches, led, jacks, and power supply in the enclosure.
Finally I installed the circuit board and did all the off board wring in the enclosure.
My first impressions of the pedal are good. It is a very high gain pedal, but with the guitar volume down a little it really produced some good haronics along with a rich midrange hump for a very fat and grainy sound. After I play it for a while I may make a few modifications to it, but it works great for me now. All I need now are some knobs for it.

I cant believe you do this!!! You are amazing. Whenever i see the guts of anny kind of gizmo… it usually means i broke it beyond any means of repair. no one can void a warranty better than me. I would love a nice boss-clone overdrive distortion pedal brand “andeezy” and i want the gain control to read “off (6 o’clock) and “ITS LUMBSDEN TIME!” (CRANKED TO THE MAX)

[...] A Passionate Apathy–this is Andy Lumsden’s site. He’s a pedal builder, bassist, and guitarist. One of the best musicians you’ll meet, and also one of the most humble musicians you’ll meet. Those two normally don’t go together. Check out some of his pedal builds here: http://apassionateapathy.wordpress.com/2008/04/11/first-guitar-pedal-from-scratch/ [...]
