Where's part two?

Incredible DIY video! You serve the community well, sir. Thank you.

Did the schematic change on FreeInfoSociety? All values are present, but component names are not. Thus the video is harder to follow.

hi wampcat, I want to get more overdrive from my sd-1. And if i understand correctly i can do that by changing the R6 and the C3. When you say by doing that you get more gain, do you mean more amount of overdrive? Sorry about my english. This is very interesting, thank you

@Wattsy97 R is resistor

@christianarestegui

depends on the sound you want, the sd1 can get a little heavier if needed

How can I install an oc44 in the clipping section (insted of a diode) with the three legs of the transistor.

[jpmnlop]

Hi, how can I install an oc44 in place of a clipping diode, since the oc44 have 3 legs and a diode 2. Thanks

hey i was just modding my sd-1 to be more like a tube screamer and now the tone knob has absolutely no effect. Do you have any suggestions

SD-1 is the clear winner in my book.

I've not found a single OD on the market at any cost that I like better...at least for Strats.
