This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.
Here's the grey spec DOD Overdrive 250 that fits in a 1590a enclosure. You could also build a yellow spec 250 or the MXR Distortion + with this layout. Just compare the schematics and value swaps.
Verified It works!!! Perfect tone ! Remember me about Danelectro T bone distortion, a Smootly and Warm tone. But you should use 3pdt eady wiring system, (is the same as General Layout Notes, but without the jumper starting from the pin #1). Thanks for this gift!
Por acaso alguem pode me mostrar um esquema simples para o ligamento dos potenciometro, sa chave lida e desliga da entrada do plug da guitarra o led etc....
I'm checking it, when ready I'll notify.

Sorry * 3PDT easy wiring system.
DeletePlease show the list components details, voltage, capacity. Thanks!
ReplyDeleteFunciona excelente el pedal +10
ReplyDeleteI think...
ReplyDeletenear input 2n2(capaitor) to 2m2(resistor)
LM741 2pin 4n7 to 47n , 47k to 4k7
22u to 4u7
2n2 parallel diode to1n
I MADE THIS PEDAL AND IT WORKS THANK YOU VERY MUCH!
ReplyDeleteI can't find the C500K pot, only C250K and C1M, can I use any of them in place of C500K? If so, do I need to make any mod? Thanks!
ReplyDeleteC1M would probably be ok.
Deletecan you replace the 4.7nf with 6.8nf
ReplyDeletegreat
Deletewhat about level pot is it lin or log
and the 10uf can it be replaced wit 22uf
Yes it can. Level pot is log as it says in the layout.
Deletesoz my mistake
Delete25pf with 100pf by any chance
Yes, or just omit it.
Deleteomit?
DeleteYeah, don't populate it.
Deleteok
Deletewill it work with c50k
DeleteNot well.
Deletei know it probably wont work but b500k?
DeleteIt will, but the sweep won't be great.
Deletesweep?
Deleteonce again sorry for all the questions
Hi, can I replace 25pF with 24pF or 27pF. and if so, which one(24 or 27) would be better?(sorry for my English)
ReplyDeleteEither one is fine. I'd go with 24pF
DeleteThanks!
Delete
Deleteit would be bad to occupy one of 30pf?
Verified
ReplyDeleteShould I plug the jacks into the free terminals on either side of the ground?
ReplyDeleteHow to turn on the 3pdt key?
ReplyDeleteWorks pretty well! Thanks from Brazil!
ReplyDeleteGain connection incorrect!!!!
ReplyDeletewhere is the distort? is it ? so clean
ReplyDeleteReplace the 47k resistor going to lug 3 of the gain pot with a 4.7k
