DIY mod for DS-1 successful.

[sepultura]

Had some spare time last week and played around (yet again) with the DS-1. I think I finally got the tone I wanted: a round fat tone with mild to moderate distortion and none of the ugly thin tinny sounds you get from the stock DS-1.

Btw, if anyone wants to try it out, you can drop by my place and bring along a stock DS-1 to compare. It is very different. Articulation is excellent, and it is very responsive to picking intensity. The range of distort varies from almost nothing to mega distortion, unlike the stock DS-1 which gives you between mild fart to loud fart.

Some of the changes are:
R39 : 15K, 1%
47pF cap in parallel with D5
R35 : 1K2, 1%
R14 : 1K5
R13 : 3K2
D5 : LED
C14 : 1uF
C12 : 0.047uF
C11 : 0.047uF
C8 : 1uF
C5 : 0.22uF
C3 : 0.1uF
C2 : 0.68uF
C1 : between 0.047-0.1uF

The danelectro daddy-o is another nicely moddable pedal. The TL072 can be replaced by other op-amps with different characteristics.

Congrats on the mod.
Wondering if anything can be done to the G2.1u, it sucks that it can't be connected to stompboxes.

You can get a white LED too. I installed one for a daddy-o, which takes a big fat LED. Looks really nice.

You need to be real careful while soldering blue LED's, since they are generally more delicate than red ones. It's easy to blow them.

haha where to get those cool LEDs?im intending to change my pedal's LEDs soon.
