Changing 1 resistor made my DS-1 useable

    for other than a doorstop.

    You guys have been holding out. I found out yesterday that changing R9 to a 1k dramatically drops the gain and harshness in the pedal. I actually ran the DIST knob at at the 2:00 area after the mod and it sounded darn nice.

    It's actually a 2 resistor mod, but since Radio Shack didn't have a 150k for R6 I just did the 1 resistor mod and don't really feel changing R6 may even be necessary.

    Fun stuff!

    Ya, that's a great mod. There isn't really much that needs to be done to a lot of the kinda mediocre sounding Boss circuits to make them way better and more useable. Great designs, there just seems to have been a couple of odd choices for component values.

    ok - so now what are you gonna do about the tone suck on the DS-1.
    Much easier to just buy a good pedal to begin with hehehe

    Well, used for $25 and a resistor for a few cents isn't bad. Plus it's enjoyable to get out the soldering iron and desoldering braid and have at it.

    I've had my share of high dollar pedals and aren't they just variations of what's out there?

    I will probably use it as a boost with the level up and DIST to for volume. It wasn't really even useable in this way before.

    NOOB alert!!!
    ok, I got some resistors at my local RS, but the colored lines do not match the old ones, will they work?

    The one in the ds-1 is: Red, Red, Black, Gold
    the one(s) I bought is: Brown, Black, Red, Gold,

    tha package on the new ones say 1k-ohm 1/4 watt

    The colored lines on resisters are a code to tell you their value. The replacement resistors SHOULD have different colored lines, because they are a different value. No worries, go ahead and mod!

    thanks romo! I just talked to a buddy of mine who knows this stuff. He said the same thing.

    EDIT: Just did it, Sounds like OP said less gainy and more useful as a boost/od. I have another stock DS-1 so I A/B ed
    The stock is much harsher (ice picky). You do sacrifice some gain but the overall tone and Od is nicer.

    Thanks Jack for making the info available. BTW does changing R6 to 150k make a noticeable difference from 100k?

    Changing R6 does make a difference but it will be slight. You can get a good sound with just the change of R9 to 1k.

    regards, Jack

    Just thought I'd pop in and say I still have the modded pedal and it works great as a boost - cranking the Level and using the Dist. knob for volume. Wasn't even usable (for me) before the mods.

    BTW, I did get the 150k for R6.

    ^^ Amen, on that. I did this mod thanks to your thread and you (soCalSteve was so kind as to send me a few 150k to put in my DS-1!!) it makes it a very usable od!
    I still have mine.

    Thanks soCalSteve (and amz-fx)

    Just bought a $30 DS-1. Gotta mod it when I get it.

    Alot of mods for these out there, for sure.

    This particular mod drastically reduces the gain, which you may or may not want. I'm basically using it like an OD instead of a Dist. unit (I probably should have got an SD-1 to begin with LOL).

    150k is a less common value resistor, so they may not have them at Radio Shack. If there are any local computer electronics stores in the area give them a try.

    ^ thanks, but check Post #16. I dont have any computer electronic stores near by though.
