This instructable outlines steps for creating your own clone of the popular ‘tube screamer’ guitar distortion stompbox. Even if you’re not keen on making tubes cry out, it’s a good introduction to the DIY effects box process (and what motivates players to make their own) –

I never really considered building my own guitar pedals. I always thought that it was best if I left it to someone else to build the tools which would build my tone.
When I first got into guitars, I played accoustic and the funny thing was that even though I had been playing for about 2 years, I still knew nothing about gutiars.
My first distortion pedal was the FAB Metal pedal. It was cheap. Thats really all I can say about it. The next pedal I got was the classic Boss DS-1. WIth the DS-1, I began to wonder about it and finally came accross a website which show me how to mod the pedal. At this point, I decided that I create my own tone and that is exactly what I will be doing in this instructional.
