Hello guys,
I have a question, does anyone know some good mod for DS-2 Turbo Distortion? I have found this pedal as sounding really nice and I am curious if there is any way to mod it and make it sound like heaven. I were searching this forum and couldn't find any mod for DS-2.
Thanks for help!! |

| i can post internal pics of my modded ds-2 if someone can explain to me whats been done. Its a SEM too. Pretty much it sounds like more gain and easy feedback. I would love to tweak it a bit but dont know how! help? |

The LED, I assume is D15, is a bit pointless unless you use a booster before the DS2. At that point in the circuit the signal level is so low that no signal will be clipped. A better place to put the LED is D8 or D9, or/and D11 and D12.
For R62, the original value is 4.7k which correspond to a highpass frequency cut-off of ~ 33Hz. Reducing this value to 1.1k will increase the cut off to 144 Hz. This will probably make the effect less fuzzy.
I can't see the new value of R14 very clearly but I can assure you it will have no significant effect on the sound of the pedal. It is used on the bypass circuit as a bias resistor for the buffer transistor.
All in all not a very effective set of modes (in my view).
Could you also post the component number of the blue capacitor near R44 ? |

The LED is D15.
blue capacitor has a symbol or logo looks like an A/triangle then says 1w8. Top of it thats visible in the photo says... haha i forget so ill just say (electrical symbol)1J100.
All i want to know is what was done to allow feedback to be produced easily. I compared to my standard ds-2 and all i can say is that the standard ds-2 at full level is equivalent to the modded ds-2 at about 6.5 level. The Modded DS-2 is a bit more clear sounding and produces feedback very easily. |

| Looks like there are some diode changes at D8 and D9. Also resistors in series around r56 and r57 |

| So can anyone tell me what part of this mod allows easy feedback to occur? please? |

Here is a mod I have just done for a customer - wanted a LOT less gain and the harshness reduced and a more valve like tone, also the ability to switch back to old pedal, with more transparency.
I'll make no apologies for the state of guitar playing - I tired and I need a beer !

PS - equipment used for demo
30 Hayden MOFO head amp- (settings 0-10) gain at 1, all tone controls at 5.

| maybe you can help scarymonsta your mod seems to be the opposite of my modded ds-2. What part of the ds-2 controls the gain. You reduced it but mine is increased. Im pretty sure the increase allowed for easier feedback which is what i want but im new to modding so im unsure what part controls this. |

Thanks Dr. Bob.
I believe it's R62 that you are going to want to change to lower/raise the gain. Stock is 4k7. Lowering it should give you more gain. Looks like you have a 1k in there. |

Experiment with the values of the combination of R54 and R56 as well.

Hi Ptak,
You can increase the maximum gain if you would reduce the value of R54.
I also would try to change the type of D8-D9 diodes as well as D11-D12 - would be intresting to try there red LEDs or faster/slower diodes.
