Uh how confusing, which one do you want, SD-1 or DS-1?

I used most of these sites for my SD-1

here's some

here's some I posted a while back ..:

SD-1 Mod 1 ... "Freak Box"

Very Tubescreamer-ish

All caps are Panasonic Metal Film, Resistors Metal Film as well.

1. Replace 4558DD with RC4558P
2.  C1,C3 - .047 ( same value just better cap - some say it makes a difference, some don't ... )
3.  C2,C7,C10 - 1uf
4.  C4 - .22uF
5.  Remove C6
6.  C8 - .1uf
7.  R4, R17 - 10K
8.  R7,R9 - 1K
9.  R16 - 100 ohm
10. R2 - 620k
11. D4 - 1n4001 and 1N34 series
12. D5 - 1N4001
13. D6 - 1N4001 and 1N34 series

The diodes arrangement comes from Brian's F&*&^ F^&^%$ mod ... the rest was taking a peak at the circuit and making it more Tubescreamer like. 

I didn't want to duplicate the TS808 circuit with this, which would require quite a few more changes, I wanted to get the sound of my Modded TS808 with a bit of that FullDrive clipping with minimal part swapping. Use 2 914/4148 diodes to get more of a TS808 clipping style.


Here's another:

SD-1 Mod 2 ... "Big Yeller Mod" Nice Fat and gainy!

All caps are Panasonic Metal Film, Resistors Metal Film as well

1. Replace 4558DD with RC4558P

2. C1,C8 - .047uf ( same values just better caps )
3. C2,C7,C10 - 1uf
4. C4 - .018uf ( same value better Cap )
5. Remove C6
6. R9 - 2.4k
7. R2 - 620k
8. C3 - .1uf
9. R6 - 2.4K

Basically sounds like an SD-1 but bigger!

have fun! ......
