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 a good sounding lower gain overdrive from Friedman. Several options with this circuit with clipping and tone options on toggle switches. Fairly transparent, as they say.
Hi, Thank you very much for sharing. Built it and works so cool, I like this. If I change caps at hi-cut section with larger value, will it cut hi more or less? Could you please teach me?
Need some help again, I can't get 1n5817 in shops, can I use 1n4001 instead, also, I just can get a B1M intead of the suggested A1M pot, can I just use the B1M pot?
Verified ..very good sound OD..Done on Perf board. Used JRC4558,HI CUT caps are, 2.2 nf instead of 22n,and 3.3n instead of 39nf. Thanks & more DIYs TO Effects Layouts..from Manila,Phils.
First of all, thank you for this blog, it´s amazing and really help me. I build this project twice, I verified everything. And with the switches in the middle position (no clipping, and no hi cut), with the gain all the way up, it sounds a noise behind the note (I don´t know how to explain it), but it´s an unpleasent noise. Someone, or everyone have the same issue?. Any idea about what could be?. I tested it with several amplifiers and guitars, with the same result. Thank you
Its true: HI CUT caps are, 2.2 nf instead of 22n,and 3.3n instead of 39nf! look at the scheme https://www.pedalpcb.com/docs/AurumDrive.pdf Nice over, tried LF 353n, JRC 4558, 4580, Opa 2604,NE 5532,TL072. Took JRC 4580. Sound like Timmy or Vemuram, only with led clipping
I'm new to the DIY scene. Can someone please give me a complete explanation and/or the values of the parts? so that I can order the right ones. There is a few that I'm unsure of, especially the capacitors. Thanks!
Built and verified (perf). Works perfect! Thanks D!
ReplyDeleteFast work! Thanks Peter.
DeleteAlright! Speedy Pete is back in action!!!
DeleteYour ability to verify has always impressed me, man. I can hardly keep up with the projects I've started to build.
Wad, first of all you have to build new garage for new pedals!
DeleteOf course!!! Great idea, Vit!
DeleteThanks a lot!!!I`ll try it!
ReplyDeleteFor volume and tone, pls kindly advise where is lug 2 connect?
ReplyDeleteLug 2 Volume goes to output. Lug 2 tone ties in to Lug 1 tone.
DeleteTone - Lug 2 connects to the 47nF cap.
DeleteVolume - Lug 2 connects to output.
And holes for these connections are already provided in both pcb and perf board images.
DeleteHi,
ReplyDeleteThank you very much for sharing. Built it and works so cool, I like this.

Oops, thanks a lot for kindly help

ReplyDeleteThanks again for help
A 4001 will work fine, as will a B1M. The sweep of the pot will just be different than the original.
DeleteThanks so much for the kindly help
DeleteSurprisingly nice sound considering the bare bones look of the circuit, gets a lot closer to a klon/timmy than you would probably expect.
ReplyDeleteHi, by what can we replace lm833
ReplyDeleteAny dual opamp should work. TL072, 4558, etc.
Deleteok thank you so much, i will test with
DeleteI love this pedal and after various tests, I prefer with 4558. Thanks

hi all, Can someone explain the meaning of the LED diodes on this pedal ?
ReplyDeleteI built the pedal and it sounds great but the LEDs don't light up. thanks
They're just being used as clipping diodes. They're not supposed to light up necessarily.
Deletesuper thanks !!!!

Deletecan i use spdt switch ??
ReplyDeleteYes, that's what it should be actually. SPST in just on/off and a typo on my part.
Deleteok, thanks a lot
