Tools, Tones and Toys for Guitarists
[Updated 4th July 2014 – correction to treble control resistors] Note: A new revision of the Klon layout has been done which is smaller and makes better use of the space, so if you want to build this I’d suggest using that layout instead which will also be easier to fit in a 1590B for … Read more
This really doesn’t need an introduction, one of the most iconic and important effect pedals to have ever been produced and an essential part of Jimmy Page’s tone on at least a couple of well known Led Zeppelin albums. If you don’t have one then just build it. Get a measured set of PNP germanium … Read more
After a thread on Freestompboxes, I thought it would be interesting to try out a few layouts using inline opamps and see how they compare in board size. Tayda sell the NJM4558 which would be perfect for a lot of these effects and so I thought it would be good to see how the layout … Read more
And the other version with symmetrical clipping and slight component value variation. So this is the bufferless Tubescreamer:
Lovepedal’s bufferless Tubescreamer with asymmetrical clipping. Actually I think that makes it a bufferless Boss SD1
Update: aegert on FSB has experimented with the circuit and has found that putting a low value cap like 820pf between pins 1 and 2 of the opamp really improved the pedal. He also suggests that a 500K log pot is much better for the Gain control, so give that a go. Update 2: daz … Read more
[27th May 2014 – Revised layout posted] Info about the great sounding original: The Crunch Box Distortion is my take on the high gain British. The history of the Crunch Box actually goes back a few years. I came up with the design after careful study of the way that modern British style amps get … Read more
Note the pin layout required for the transistors. This will accommodate many modern NPN silicon transistors, but you will need to either alter the layout or twist over pins if using transistors with a different pin layout like the 2SC828s used in the original. One for a 1590BB, but I’ll do a 1590B friendly version … Read more
Another popular pedal and rightly so, this is a great sounding overdrive. Geiri’s video of his Zendrive build with AMZ MiniBooster in the same box. Thanks for the vid mate:
