Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
I've searched on google for an explanation but I don't really found and answer on my question: why are the letters of the transistors in an other order? Could someone please explain this clear to me? Thanx
Well spotted. That was done simply to fit the layout. The normal pin order for the 2N3904 is CBE, but the collector of Q1 needs to be directly connected to the base of Q2, and so if I'd kept the transistors in their normal layout I would have needed at least an additional two columns and extra links, whereas by simply twisting over a couple of the pins, the rest of the layout flowed logically.
Just twist the collector and base around on Q2 (the right hand transistor) and it'll work fine. If you want to you could use some small lengths of wire insulation cut offs to insulate the legs and make sure the pins don't touch each other when you do it.
I've build the pedal, but my dc jack has only two pins instead of three. I don't know which one is pos and which one is neg. There is one pin more in the middle and one pin more to the edge.
If it only has two pins then it isn't a switched jack, meaning it can't be used to disconnect a battery when the plug is inserted. I still use those all the time because I never use a battery snap in builds for myself. In terms of which pin is which, it totally depends on the actual jack, so there's no consistent answer. Mine have one pin slightly longer than the other and that is the positive side, but to be certain I'd suggest using a multimeter in a resistance or continuity mode, and see which lug is connected to the centre pin. Whichever is will be the negative side.
Hey guys.I'm an absolute newbie on making pedals.I tried this circuit but with no success.The signal passes through the circuit and i can hear it on the guitar amp,but no fuzz going on there.Also there is a hum (that i supose is ground problem).I built this on a perf board.Can any brother help me out and send me a clean picture of their built?I want see what board you used and how you used it.Thank you!
Hey man thanks for this layout its sweet. Here is one that I built up http://asobernewt.blogspot.com/2010/10/mamoth.html
ReplyDeleteNo problem, glad it was useful to you. And thanks for linking the pic, I love to see the results when people have used the layouts. Cheers
ReplyDeleteHere's a stupid question. What are the values of the potsV
ReplyDeleteSorry, I do forget to put in the fundamentals sometimes! :o) The pots are:
ReplyDeleteWool - 2K lin
Pinch - 500K lin
EQ - 10K lin
Output - 10K lin

ReplyDeleteOk, thanx, and a happy new year!!!
